That is partially correct because oxygen does technically decrease because the molecules spread out and that results in oxygen content being depleted in each breath and also it would be at a higher pressure not lower.
Its less oxygen in the measured amount. If you measures the oxygen atoms in the air at sea level and measured the amount at the edge of space there would be less atoms of oxygen
Did you forget that jet engines need oxygen? The lack of oxygen is an issue for the pilots starting around 14,000 feet. So it’s not an new issue, and on board system work basically the same at the higher altitudes.

While rolling, move the stick hard right, I could count seconds before any roll to the right. I was told by many the math models for the simulator were very accurate. The IPs, many Vietnam pilots, for the 1st German Air Force said the sum was pretty accurate in replication. It would also be very prone to flat spin at this altitude. Many times I it didn’t recover (with a nose down engine air-restart) until about 15k AGL. This was not using drag chute deployment as is prescribed to recover.

@@15Hours_ago What an incredible stupid comment. Less oxygen molecules but contains the same amount of oxygen? No! Less molecules of oxygen is the same as less oxygen. Period.
@@213BRANDONP I’m pasting this straight from google (The percentage of oxygen in the air is same at sea level as it is at high altitudes, which is around 21%. However, at high altitudes the pressure is lower and air is more spread out. This leads to less oxygen availability for the body in each breathe.) look it up I hope you were drunk when you wrote that.
The phantom had unique issues the primary one being their engines would likely either flame out or light on fire at those altitudes. Also, with the pilots not having pressure suits, any problems and the pilot would be dead in short order.
That is also why scramjets and ramjets work well in the less dense air above 40,000 ft. The air is less dense for less over pressure in the combustion chamber.
The Grumman F-14 Tomcat is an American carrier-capable supersonic, twin-engine, two-seat, twin-tail, all-weather-capable variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics-Grumman F-111B project. A large and well-equipped fighter, the F-14 was the first of the American Teen Series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War. The F-14 first flew on 21 December 1970 and made its first deployment in 1974 with the U.S. Navy aboard USS Enterprise (CVN-65), replacing the McDonnell Douglas F-4 Phantom II. The F-14 served as the U.S. Navy's primary maritime air superiority fighter, fleet defense interceptor, and tactical aerial reconnaissance platform into the 2000s. The Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) pod system was added in the 1990s and the Tomcat began performing precision ground-attack missions.[1] The Tomcat was retired by U.S. Navy on 22 September 2006, supplanted by the Boeing F/A-18E/F Super Hornet. Several retired F-14s have been put on display across the US. Having been exported to Pahlavi Iran under the Western-aligned Shah Mohammad Reza Pahlavi in 1976, F-14s were used as land-based interceptors by the Imperial Iranian Air Force. Following the Iranian Revolution in 1979, the Islamic Republic of Iran Air Force used them during the Iran-Iraq War. Iran claimed their F-14s shot down at least 160 Iraqi aircraft during the war (only 55 of these confirmed, according to historian Tom Cooper),[2] while 16 Tomcats were lost, including seven losses to accidents.[2][3] As of 2024, the F-14 remains in service with Iran's air force, though in low numbers of combat-ready aircraft due to a lack of spare parts. Development Background The F-111B was designed to fulfill the carrier-based interceptor role, but had weight and performance problems, and was not suited to the types of aerial combat that were predominant over Vietnam. Beginning in the late 1950s, the U.S. Navy sought a long-range, high-endurance interceptor to defend its carrier battle groups against long-range anti-ship missiles launched from the jet bombers and submarines of the Soviet Union. They outlined the idea of a Fleet Air Defense (FAD) aircraft with a more powerful radar and longer range missiles than the F-4 Phantom II to intercept both enemy bombers and missiles at very long range.[4] Studies into this concept led to the Douglas F6D Missileer project of 1959, but this large subsonic aircraft would have limited ability to evade supersonic fighters or defend itself once it fired its missiles, and the project was cancelled in December 1961.[5] The Navy still sought long-range defensive aircraft, but with higher performance than the Missileer. The Navy was directed to participate in the Tactical Fighter Experimental (TFX) program with the U.S. Air Force (USAF) by Secretary of Defense Robert McNamara, who favored versatile aircraft that could be shared by both services, reducing procurement and development costs. To this end, he had already directed the USAF to buy the F-4 Phantom II-which was developed for the Navy and could serve both as a fighter-bomber and an interceptor aircraft-instead of buying more F-105 Thunderchief and F-106 Delta Dart aircraft to fill each respective role.[6] The TFX had adequate speed, range and payload for the FAD role, but was designed primarily as a fighter-bomber and interdictor that lacked the maneuverability and overall performance that the Navy expected. The Navy strenuously opposed the TFX as it feared compromises necessary for the Air Force's need for a low-level attack aircraft would adversely impact the aircraft's performance as a fighter. Their concerns were overridden, and the project went ahead as the F-111B. Lacking recent experience in naval fighters, the F-111's main contractor, General Dynamics, partnered with Grumman to provide the experience needed to develop a naval version. Weight and performance issues plagued the program, and with the F-111B in distress, Grumman began studying improvements and alternatives. In 1966, the Navy awarded Grumman a contract to begin studying advanced fighter designs. Grumman narrowed down these designs to its 303 design.[7] The name "Tomcat" was partially chosen to pay tribute to Admiral Thomas F. Connolly, as the nickname "Tom's Cat" had already been widely used within the program during development to reflect Connolly's involvement, and now the moniker was adapted into an official name in line with the Grumman tradition of giving its fighter aircraft feline names. Changing it to Tomcat associated the aircraft with the previous Grumman aircraft Wildcat, Hellcat, Tigercat, and Bearcat propeller fighters along with the Panther, Cougar, and Tiger jet fighters. Other names considered were Alley Cat (considered inappropriate due to sexual connotations) and Seacat.[8][9] VFX Through this same period, experience in Vietnam against the more agile MiG fighters demonstrated that the Phantom lacked the maneuverability needed to win in any engagement. This led to the VFAX program to study new fighter aircraft that would either replace or supplant the Phantom in the fighter and ground-attack roles while the TFX worked the long-range interception role.[10] Grumman continued work on its 303 design and offered it to the Navy in 1967, which led to fighter studies by the Navy. The company continued to refine the design into 1968.[7] Around this time, Vice Admiral Thomas F. Connolly, Deputy Chief of Naval Operations for Air Warfare, flew the developmental F-111A variant on a flight and discovered that it had difficulty going supersonic and had poor carrier landing characteristics. He later testified before Congress about his concerns against the official Navy position and, in May 1968, Congress stopped funding for the F-111B, allowing the Navy to pursue an answer tailored to its requirements.[11] Free to choose their solution to the FAD requirement, VFAX ended in favor of a new design that would combine the two roles. In July 1968, the Naval Air Systems Command (NAVAIR) issued a request for proposals (RFP) for the Naval Fighter Experimental (VFX) program. VFX called for a tandem two-seat, twin-engine air-to-air fighter with a maximum speed of Mach 2.2.[12] It would also have a built-in 20 mm M61 Vulcan cannon and a secondary close air support role.[13] The VFX's air-to-air missiles would be either six AIM-54 Phoenix or a combination of six AIM-7 Sparrow and four AIM-9 Sidewinder missiles. Bids were received from General Dynamics, Grumman, Ling-Temco-Vought, McDonnell Douglas, and North American Rockwell;[14] four bids incorporated variable-geometry wings.[13][N 1] Full-scale development Grumman's VFX entry was designed around the TF30 engine, AWG-9 radar and AIM-54 missile intended for the F-111B; this eventually became the F-14A. McDonnell Douglas and Grumman were selected as finalists in December 1968. Grumman's 303E design was selected for the contract award in January 1969.[15] The design reused the TF30 engines from the F-111B, though the Navy planned on replacing them with the Pratt & Whitney F401-400 engines under development for the Navy, along with the related Pratt & Whitney F100 for the USAF.[16] Though lighter than the F-111B, it was still the largest and heaviest U.S. fighter to fly from an aircraft carrier, a consequence of the requirement to carry the large AWG-9 radar and AIM-54 Phoenix missiles (from the F-111B) and an internal fuel load of 16,000 lb (7,300 kg). The design service life was 6,000 flight hours, although this was later extended to 7,200 hours.[17] Upon winning the contract for the F-14, Grumman greatly expanded its Calverton, Long Island, New York facility for evaluating the aircraft. Much of the testing, including the first of many compressor stalls and multiple ejections, took place over Long Island Sound. To save time and avoid cancellation by the new presidential administration, the Navy skipped the prototype phase and jumped directly to full-scale development; the Air Force took a similar approach with its McDonnell Douglas F-15 Eagle.[18] The F-14 first flew on 21 December 1970, just 22 months after Grumman was awarded the contract. The fighter reached initial operational capability (IOC) in 1973. The United States Marine Corps was initially interested in the F-14 as an F-4 Phantom II replacement, going so far as to send officers to Fighter Squadron One Twenty-Four (VF-124) to train as instructors. The Marine Corps pulled out of any procurement when the development of the stores' management system for ground attack munitions was not pursued. An air-to-ground capability was not developed until the 1990s.[18] Firing trials involved launches against simulated targets of various types, from cruise missiles to high-flying bombers. AIM-54 Phoenix missile testing from the F-14 began in April 1972. The longest single Phoenix launch was successful against a target at a range of 110 nmi (200 km) in April 1973. Another unusual test was made on 22 November 1973, when six missiles were fired within 38 seconds at Mach 0.78 and 24,800 ft (7,600 m); four scored direct hits, one broke the lock and missed, and one was declared "no test" after the radar signature augmentation in the target drone (which increased the apparent radar signature of the tiny drone to the size of a MiG-21) failed, causing the missile to break track. This gave a tested success rate of 80% since effectively only 5 missiles were tested. This was the most expensive single test of air-to-air missiles ever performed at that time.
Alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2). PAO2= (PB−PH2O)FiO2−(PaCO2÷R) where PB is the barometric pressure, PH2O is the water vapor pressure (usually 47mmHg for moist air but in our case 0, as the pilot would have to breathe dry O2), FiO2 = fractional concentration of oxygen inspired by the pilot. The max FiO2 is 1 but no one can breathe 100% oxygen, it would give the pilot a bad headache. For practical purpose, lets say the pilot breathes an FiO2 of 0.6. PaCO2 is the exhaled CO2 ~ 40 - 45 mmHg in healthy adults. R is the gas exchange ratio (0.8 for mixed diet consumers) PB = 82 mmHg at 50000 ft (from 760 mmHg at sea level) Solving the equation PAO2= (82-0)x 0.6 - (45÷0.8) = (82x 0.6)- 56 = 49.2 -56 = -6.8 PAO2 cannot be -6.8, the pilot would be dead. So the only thing we can change in this equation is increasing the barometric pressure (PB), which is done by pressuring the O2 supplied and giving dry oxygen, so that the PH2O is near 0. The higher alveolar oxygen makes it easier for O2 to latch on to the hemoglobin in the RBC's. In reality, as the aircraft scales height, the barometric pressure keeps dropping, making it harder and harder for the pilot to breathe.... Thats why a pilots pulmonary fitness is of utmost importance.
These might be limiting factors for some planes, but with bottled oxygen and enough power, this is more than possible. The real reason fighter jets and even the Concorde are capped at 60k is because the pressure outside is so low that your blood would boil at body temperature. So in the event of a depressurisation above 60k, occupants would experience severe hypoxia, and die or have significant brain damage (which has happened to some U2 pilots). This is the reason U2 and SR-71 pilots use pressure suits as they fly above the coveted 60k ft.
So a plane that May climb to 100000ft shot down a sat that is orbiting from 250miles to 3000 miles above earth? Traveling from 7000 to 17000 miles per hour. Which is faster than any known missile even as of now. In other words bs and propaganda at best. I’m sure the gov said it so it must be true right.
Which is why a scram jet is needed, like the SR-71 blackbird, which had typical jet engines, but with a twist: once it got to altitude, its engines redirected air and tightened all its nozzles, and became a scram jet, in essence. Not a specific, dedicated scam jet, but for all intents and purposes, that's what it was and altitude going mach 3.5-4. it could theoretically reach above mach 5, but that would have run the risk of the jet being torn apart from air drag, which is pretty impressive, considering how thin it was at that altitude.
Some Russian MiGs fly up to 100,000ft. Watched a video of this exact thing. They launch from a base in Siberia on a runway made of ice. There's video of it on RUclips. They offer civilian flights, in which they have to test and pass physicals.. it was a good watch.
Military aircraft have Liquid Oxygen Systems (LOX) and pressurized cockpits so that pilots have plenty of breathable air at high altitudes. The main thing that affects an aircraft’s service ceiling or absolute ceiling is the lower ambient air pressure causing engines to develop less power/thrust as they ascend.
Have you ever heard of the bens, that’s why SR71 pilots wear space suits, and the less dense air is like trying to make a watercraft fly in the air above the water. Not dense enough to support it. In that rarefied air is the realm of the hypersonic aircraft, where the compression of the air molecules is enough to create lift, and combustion better than at lower altitudes. The problem is that as the speed increases it creates heat trama and structural compression of the airframe beyond safe limits for piloted aircraft. That is why the SR71 is revolutionary, they created a hypersonic aircraft with slide rules and drafting paper!!! Simplified explanation but that is what it is.
I think the records are also different in case of zoom climbs and sustained flights on a certain high altitude. The engines also need dense enough oxygen not to flame out, so you would need onboard oxygen for combusting fuel up there as well. That is another reason.
also don't forget about "coffin corner" which is a certain point in altitude where your speed has to just be increasing constantly to be able to even make it in that environment; but if you have something like a scramjet engine or an engine that's actually meant to go that fast; it won't be a problem; but flying something like the U2 which really has to be kind of high and it still kind of slow is has only a very narrow window of margin where the speed will either be so fast it will destroy the aircraft or too little speed will make the aircraft fall out of the sky!!!! so only certain jets can get to Or above 70,000'ft.!!
Pilots have good enough oxygen. It's the engines that are suffocating. No oxyygen means no burn, and bo burn means no engine. That's why space rockets have oxidizer mixed with their fuel, otherwise they wouldn't work.
I'm pretty sure it boils down to engine flameouts and such... The engines provide compressed oxygen in most cases, and there's sometimes an oxygen tank onboard for the pilot if that has any issues.
Along with the thinner air comes reduced lift capabilities, because the plane has less and less to support it at the speeds they travel. You'd have to go faster and faster(more than you gain by less air resistance) to maintain a flight profile. That's why the wings on a rocket are so small- because of their tremendous velocity, if they were bigger they'd interfere with air flow and destabilize the whole shooting match.
It’s usually limited by the engine as it provides for the environmental systems among others. Also the air is too thin for the wing and control surfaces to be effective. It is possible to zoom climb above max alt but will not have any aileron nor elevator control and then you don’t want the engine giving up as well.
The English Electric lightning during an exercise overtook a British Airways Concorde and then accelerated skyward to 80,000+ feet in the late 70s … Different class!
The engine dont died they runned out of oxygen intake mean they cant burn fuel so they engine shut down if the jet goes down and enought oxygen goes in the engine the pilot can restart the engine
Yes, less dense air produces less lift, but the bigger problem is that it also causes the engine to produce less power. Less power means you go slower, which means even less air through the engine, which means less power, which means you go slower.... and so on. Until inevitably there is not enough power to keep the plane in the air.
If you tied a Cessna to a balloon in such a way that would allow you to have the throttle wide open and you wore a space suit here is what will happen. You’d have to adjust the fuel/air mixture to a leaner setting to keep the gas/air mixture proportional. As a result your rpms will gradually drop. Eventually there wouldn’t be even enough breathable air to keep the engine turning and it would idle on the edge of a stall until finally the propeller stops entirely. You could release the plane and as you get down to denser air you could then finally start the engine again and land the aircraft safely with full power again.
They can't get lift beyond max altitudes due to air density issues, but if they switch to rocket fuel they can continue to ascend (but fighter jets don't use rocket fuel). Pilots in fighter jets use liquid oxygen tanks or LOX, not bleed air from engines at high altitudes, so they can still breathe and perform.
50-60k Ft? However atleast two aircraft that I know of went well above that on a regular basis, the U-2 & SR -71 oh and the A-12 and BTW all Kelly Johnson aircraft! That absolutely says something about the man and his men & women that worked along side him!

Yeah I think it has more to do with the lack of oxygen at higher altitude which the engines need to operate. This is the main reason rockets don’t use traditional combustion engines that rely on the oxygen in the air to function properly.
LOL! If that was the case, you could solve it simply by having a relatively small oxygen storage for the time the jet is over the critical altitude for the pilot. The one thing you cannot solve with jet engine (as opposed to rocket engine, where oxidant is liquid or solid) is the oxygen for burning the fuel!
You can fly at high altitudes as long as you are going fast enough for enough airflow for the engines Its one reason why scramjet technology works more efficiently at super high altitudes
Pilots usually can wear pressure suits and have breathing oxygen for such conditions, and someone already mentioned, it’s not a lack of oxygen, it’s a lack of pressure that makes it impossible to get oxygen into the lungs.
The English Electric Lightning was recorded as reaching 88,000 feet, and had to stop the climb because the pilot wasn't wearing a 'g' suit. This happened in 1984. Recorded fact.
Ultimately, it's not the lack of oxygen or lift, since any jet could be pressurized or make a parabolic flight, but rather that in insufficient air density the aircraft would become uncontrollable and potentially unrecoverable.
@@dekka888 , the Soviets never have tendered their claims before the international officials documenting for the record such events. They can boast, but they cannot corroborate independently.

Thank you
On December 6, 1959 US Navy Commander Lawrence E. Flint set a new world’s record when he zoom climbed his YF4H-1 Phantom II prototype to an altitude of 98,561 feet or 30,041 meters.

Thanks for answering the question.
I took the F-15,C to 82,000 ft, and the record for the plane is about 105,000 feet. These are zoom climbs however, and do require partial or full pressure suits.
I could watch these beautiful works of art dance in the sky all day long and never get bored.
Also, the less oxygen at higher altitude can create a flameout in the engines.
Less oxygen molecules but it still contains the same amount of oxygen at all altitudes buddy

@@213BRANDONP I’m pasting this straight from google (The percentage of oxygen in the air is same at sea level as it is at high altitudes, which is around 21%. However, at high altitudes the pressure is lower and air is more spread out. This leads to less oxygen availability for the body in each breathe.) look it up I hope you were drunk when you wrote that.

One and only Reason: The Jet engine looses it's power due the lack of oxygen.
Wouldnt the human body be inflated when the airpressure goes to zero?
@@elpoiken 1. you're in a g-suit, it's already squeezing you.
2. you breath, so you don't hold your breath from sea level to 130,000 feet...
F4 Phantom built in the late 50's made it to 98,000.
The phantom had unique issues the primary one being their engines would likely either flame out or light on fire at those altitudes. Also, with the pilots not having pressure suits, any problems and the pilot would be dead in short order.
Facts‼️ Well Spoken 💥👍💥
That is also why scramjets and ramjets work well in the less dense air above 40,000 ft. The air is less dense for less over pressure in the combustion chamber.
Among all the American jets in the video, the flanker stands out. Such a marvel in aircraft. Flanker fans like
You forgot about the air breathing engines.
Jet engines are compression engines so they aren't limited by air density. The engine blades can spin faster at altitude.
Thanks for explaining
The jets carry LOX - liquid Oxygen tanks for the pilots. If there is 1 pilot and 1 RIO they each get a LOX tank like on a EA-6B
The Grumman F-14 Tomcat is an American carrier-capable supersonic, twin-engine, two-seat, twin-tail, all-weather-capable variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics-Grumman F-111B project. A large and well-equipped fighter, the F-14 was the first of the American Teen Series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War.
The F-14 first flew on 21 December 1970 and made its first deployment in 1974 with the U.S. Navy aboard USS Enterprise (CVN-65), replacing the McDonnell Douglas F-4 Phantom II. The F-14 served as the U.S. Navy's primary maritime air superiority fighter, fleet defense interceptor, and tactical aerial reconnaissance platform into the 2000s. The Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) pod system was added in the 1990s and the Tomcat began performing precision ground-attack missions.[1] The Tomcat was retired by U.S. Navy on 22 September 2006, supplanted by the Boeing F/A-18E/F Super Hornet. Several retired F-14s have been put on display across the US.
Having been exported to Pahlavi Iran under the Western-aligned Shah Mohammad Reza Pahlavi in 1976, F-14s were used as land-based interceptors by the Imperial Iranian Air Force. Following the Iranian Revolution in 1979, the Islamic Republic of Iran Air Force used them during the Iran-Iraq War. Iran claimed their F-14s shot down at least 160 Iraqi aircraft during the war (only 55 of these confirmed, according to historian Tom Cooper),[2] while 16 Tomcats were lost, including seven losses to accidents.[2][3] As of 2024, the F-14 remains in service with Iran's air force, though in low numbers of combat-ready aircraft due to a lack of spare parts.
Development
Background
The F-111B was designed to fulfill the carrier-based interceptor role, but had weight and performance problems, and was not suited to the types of aerial combat that were predominant over Vietnam.
Beginning in the late 1950s, the U.S. Navy sought a long-range, high-endurance interceptor to defend its carrier battle groups against long-range anti-ship missiles launched from the jet bombers and submarines of the Soviet Union. They outlined the idea of a Fleet Air Defense (FAD) aircraft with a more powerful radar and longer range missiles than the F-4 Phantom II to intercept both enemy bombers and missiles at very long range.[4] Studies into this concept led to the Douglas F6D Missileer project of 1959, but this large subsonic aircraft would have limited ability to evade supersonic fighters or defend itself once it fired its missiles, and the project was cancelled in December 1961.[5]
The Navy still sought long-range defensive aircraft, but with higher performance than the Missileer. The Navy was directed to participate in the Tactical Fighter Experimental (TFX) program with the U.S. Air Force (USAF) by Secretary of Defense Robert McNamara, who favored versatile aircraft that could be shared by both services, reducing procurement and development costs. To this end, he had already directed the USAF to buy the F-4 Phantom II-which was developed for the Navy and could serve both as a fighter-bomber and an interceptor aircraft-instead of buying more F-105 Thunderchief and F-106 Delta Dart aircraft to fill each respective role.[6]
The TFX had adequate speed, range and payload for the FAD role, but was designed primarily as a fighter-bomber and interdictor that lacked the maneuverability and overall performance that the Navy expected. The Navy strenuously opposed the TFX as it feared compromises necessary for the Air Force's need for a low-level attack aircraft would adversely impact the aircraft's performance as a fighter. Their concerns were overridden, and the project went ahead as the F-111B. Lacking recent experience in naval fighters, the F-111's main contractor, General Dynamics, partnered with Grumman to provide the experience needed to develop a naval version. Weight and performance issues plagued the program, and with the F-111B in distress, Grumman began studying improvements and alternatives. In 1966, the Navy awarded Grumman a contract to begin studying advanced fighter designs. Grumman narrowed down these designs to its 303 design.[7]
The name "Tomcat" was partially chosen to pay tribute to Admiral Thomas F. Connolly, as the nickname "Tom's Cat" had already been widely used within the program during development to reflect Connolly's involvement, and now the moniker was adapted into an official name in line with the Grumman tradition of giving its fighter aircraft feline names. Changing it to Tomcat associated the aircraft with the previous Grumman aircraft Wildcat, Hellcat, Tigercat, and Bearcat propeller fighters along with the Panther, Cougar, and Tiger jet fighters. Other names considered were Alley Cat (considered inappropriate due to sexual connotations) and Seacat.[8][9]
VFX
Through this same period, experience in Vietnam against the more agile MiG fighters demonstrated that the Phantom lacked the maneuverability needed to win in any engagement. This led to the VFAX program to study new fighter aircraft that would either replace or supplant the Phantom in the fighter and ground-attack roles while the TFX worked the long-range interception role.[10] Grumman continued work on its 303 design and offered it to the Navy in 1967, which led to fighter studies by the Navy. The company continued to refine the design into 1968.[7]
Around this time, Vice Admiral Thomas F. Connolly, Deputy Chief of Naval Operations for Air Warfare, flew the developmental F-111A variant on a flight and discovered that it had difficulty going supersonic and had poor carrier landing characteristics. He later testified before Congress about his concerns against the official Navy position and, in May 1968, Congress stopped funding for the F-111B, allowing the Navy to pursue an answer tailored to its requirements.[11]
Free to choose their solution to the FAD requirement, VFAX ended in favor of a new design that would combine the two roles. In July 1968, the Naval Air Systems Command (NAVAIR) issued a request for proposals (RFP) for the Naval Fighter Experimental (VFX) program. VFX called for a tandem two-seat, twin-engine air-to-air fighter with a maximum speed of Mach 2.2.[12] It would also have a built-in 20 mm M61 Vulcan cannon and a secondary close air support role.[13] The VFX's air-to-air missiles would be either six AIM-54 Phoenix or a combination of six AIM-7 Sparrow and four AIM-9 Sidewinder missiles. Bids were received from General Dynamics, Grumman, Ling-Temco-Vought, McDonnell Douglas, and North American Rockwell;[14] four bids incorporated variable-geometry wings.[13][N 1]
Full-scale development
Grumman's VFX entry was designed around the TF30 engine, AWG-9 radar and AIM-54 missile intended for the F-111B; this eventually became the F-14A.
McDonnell Douglas and Grumman were selected as finalists in December 1968. Grumman's 303E design was selected for the contract award in January 1969.[15] The design reused the TF30 engines from the F-111B, though the Navy planned on replacing them with the Pratt & Whitney F401-400 engines under development for the Navy, along with the related Pratt & Whitney F100 for the USAF.[16] Though lighter than the F-111B, it was still the largest and heaviest U.S. fighter to fly from an aircraft carrier, a consequence of the requirement to carry the large AWG-9 radar and AIM-54 Phoenix missiles (from the F-111B) and an internal fuel load of 16,000 lb (7,300 kg). The design service life was 6,000 flight hours, although this was later extended to 7,200 hours.[17]
Upon winning the contract for the F-14, Grumman greatly expanded its Calverton, Long Island, New York facility for evaluating the aircraft. Much of the testing, including the first of many compressor stalls and multiple ejections, took place over Long Island Sound. To save time and avoid cancellation by the new presidential administration, the Navy skipped the prototype phase and jumped directly to full-scale development; the Air Force took a similar approach with its McDonnell Douglas F-15 Eagle.[18] The F-14 first flew on 21 December 1970, just 22 months after Grumman was awarded the contract. The fighter reached initial operational capability (IOC) in 1973. The United States Marine Corps was initially interested in the F-14 as an F-4 Phantom II replacement, going so far as to send officers to Fighter Squadron One Twenty-Four (VF-124) to train as instructors. The Marine Corps pulled out of any procurement when the development of the stores' management system for ground attack munitions was not pursued. An air-to-ground capability was not developed until the 1990s.[18]
Firing trials involved launches against simulated targets of various types, from cruise missiles to high-flying bombers. AIM-54 Phoenix missile testing from the F-14 began in April 1972. The longest single Phoenix launch was successful against a target at a range of 110 nmi (200 km) in April 1973. Another unusual test was made on 22 November 1973, when six missiles were fired within 38 seconds at Mach 0.78 and 24,800 ft (7,600 m); four scored direct hits, one broke the lock and missed, and one was declared "no test" after the radar signature augmentation in the target drone (which increased the apparent radar signature of the tiny drone to the size of a MiG-21) failed, causing the missile to break track. This gave a tested success rate of 80% since effectively only 5 missiles were tested. This was the most expensive single test of air-to-air missiles ever performed at that time.
Astronauts take over from there on😁👍
I NOW THIS !!!😂😂😂 BUT OTHER PEOPLE NOTHINK !!! GOOD MAKE FOR BEGINNERS !!! 😉😉😉
Also Jet Engines need Oxygen for combustion of the Fuel for thrust.
Alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2).
PAO2= (PB−PH2O)FiO2−(PaCO2÷R)
where
PB is the barometric pressure,
PH2O is the water vapor pressure (usually 47mmHg for moist air but in our case 0, as the pilot would have to breathe dry O2),
FiO2 = fractional concentration of oxygen inspired by the pilot. The max FiO2 is 1 but no one can breathe 100% oxygen, it would give the pilot a bad headache. For practical purpose, lets say the pilot breathes an FiO2 of 0.6.
PaCO2 is the exhaled CO2 ~ 40 - 45 mmHg in healthy adults.
R is the gas exchange ratio (0.8 for mixed diet consumers)
PB = 82 mmHg at 50000 ft (from 760 mmHg at sea level)
Solving the equation
PAO2= (82-0)x 0.6 - (45÷0.8)
= (82x 0.6)- 56
= 49.2 -56
= -6.8
PAO2 cannot be -6.8, the pilot would be dead.
So the only thing we can change in this equation is increasing the barometric pressure (PB), which is done by pressuring the O2 supplied and giving dry oxygen, so that the PH2O is near 0.
The higher alveolar oxygen makes it easier for O2 to latch on to the hemoglobin in the RBC's.
In reality, as the aircraft scales height, the barometric pressure keeps dropping, making it harder and harder for the pilot to breathe.... Thats why a pilots pulmonary fitness is of utmost importance.
also there isnt as much oxygen for the engine to breath.
4th comment
correct
Exactly the first thing that came to my mind
It's real good that you'll put shorts out without having a clue in the world
These might be limiting factors for some planes, but with bottled oxygen and enough power, this is more than possible. The real reason fighter jets and even the Concorde are capped at 60k is because the pressure outside is so low that your blood would boil at body temperature. So in the event of a depressurisation above 60k, occupants would experience severe hypoxia, and die or have significant brain damage (which has happened to some U2 pilots). This is the reason U2 and SR-71 pilots use pressure suits as they fly above the coveted 60k ft.
Actually it's the engine compression of air. It's too thin
Great one
The f15 has shot down a satellite
So a plane that May climb to 100000ft shot down a sat that is orbiting from 250miles to 3000 miles above earth? Traveling from 7000 to 17000 miles per hour. Which is faster than any known missile even as of now. In other words bs and propaganda at best. I’m sure the gov said it so it must be true right.
Amazing
WTF???? How about less oxygen for the F-ing engines to burn.
Bro forgot that the engines need enough Air to keep working💀💀💀
Haha you missed out on the most important point....
The foxbat went into mofo space what a badass..!! 💪🏾💪🏾
Beside for defensive maneuver against incoming missile they go low close to the ground.
Which is why a scram jet is needed, like the SR-71 blackbird, which had typical jet engines, but with a twist: once it got to altitude, its engines redirected air and tightened all its nozzles, and became a scram jet, in essence. Not a specific, dedicated scam jet, but for all intents and purposes, that's what it was and altitude going mach 3.5-4. it could theoretically reach above mach 5, but that would have run the risk of the jet being torn apart from air drag, which is pretty impressive, considering how thin it was at that altitude.
The mig 25 can reach 37 000 m
So.. how did they solve the icing problem? LOL!
Some Russian MiGs fly up to 100,000ft. Watched a video of this exact thing. They launch from a base in Siberia on a runway made of ice. There's video of it on RUclips. They offer civilian flights, in which they have to test and pass physicals.. it was a good watch.
WAOOO BEAUTIFUL JET ❤
Military aircraft have Liquid Oxygen Systems (LOX) and pressurized cockpits so that pilots have plenty of breathable air at high altitudes. The main thing that affects an aircraft’s service ceiling or absolute ceiling is the lower ambient air pressure causing engines to develop less power/thrust as they ascend.
Have you ever heard of the bens, that’s why SR71 pilots wear space suits, and the less dense air is like trying to make a watercraft fly in the air above the water. Not dense enough to support it. In that rarefied air is the realm of the hypersonic aircraft, where the compression of the air molecules is enough to create lift, and combustion better than at lower altitudes. The problem is that as the speed increases it creates heat trama and structural compression of the airframe beyond safe limits for piloted aircraft. That is why the SR71 is revolutionary, they created a hypersonic aircraft with slide rules and drafting paper!!! Simplified explanation but that is what it is.
I think the records are also different in case of zoom climbs and sustained flights on a certain high altitude.
The engines also need dense enough oxygen not to flame out, so you would need onboard oxygen for combusting fuel up there as well. That is another reason.
That's why complimentary fighter drones will be that much more effective😮
also don't forget about "coffin corner"
which is a certain point in altitude where your speed has to just be increasing constantly to be able to even make it in that environment;
but if you have something like a scramjet engine or an engine that's actually meant to go that fast;
it won't be a problem;
but flying something like the U2 which really has to be kind of high and it still kind of slow is has only a very narrow window of margin where the speed will either be so fast it will destroy the aircraft or too little speed will make the aircraft fall out of the sky!!!!
so only certain jets can get to Or above 70,000'ft.!!
300,000 ft for X15A2 rocket fueled and launched from B52. Max speed Mach 6.7 still holds record for highest manned flight
Not an air breathing engine... rocket power
Never was a problem for Blackbird SR-71'/!!!
Pilots have good enough oxygen. It's the engines that are suffocating. No oxyygen means no burn, and bo burn means no engine. That's why space rockets have oxidizer mixed with their fuel, otherwise they wouldn't work.
A bigger issue is the engines can not produce enough power at altitude due to the combustion being oxygen starved.
Crew oxygen is independent of outside air.
Engine efficiency and lift are the limiting factor.
❤❤❤❤...
I'm pretty sure it boils down to engine flameouts and such... The engines provide compressed oxygen in most cases, and there's sometimes an oxygen tank onboard for the pilot if that has any issues.
Along with the thinner air comes reduced lift capabilities, because the plane has less and less to support it at the speeds they travel. You'd have to go faster and faster(more than you gain by less air resistance) to maintain a flight profile. That's why the wings on a rocket are so small- because of their tremendous velocity, if they were bigger they'd interfere with air flow and destabilize the whole shooting match.
Great vid

True but a fighter can fire its missiles higher than the airframe ceiling. Also,
Ramjets are being designed that will allow fighters to fly higher.
There was one that reached 90,000. The f4 phantom was the one I was thinking about, 90,000 ( + ).
Mig-25?
It’s usually limited by the engine as it provides for the environmental systems among others. Also the air is too thin for the wing and control surfaces to be effective. It is possible to zoom climb above max alt but will not have any aileron nor elevator control and then you don’t want the engine giving up as well.
The English Electric lightning during an exercise overtook a British Airways Concorde and then accelerated skyward to 80,000+ feet in the late 70s … Different class!
"It's over Anakin, i have the high ground!"
-some random pilot that reached a higher altitude
Nf-104 is a modified f-104 that al most reached space as it had an extra solid rocket motor that propelled it when the engine died
The engine dont died they runned out of oxygen intake mean they cant burn fuel so they engine shut down if the jet goes down and enought oxygen goes in the engine the pilot can restart the engine
@@azurlaneayanami7447 say that again but in English please
And here comes the SR-71 - hold my beer. I know it isn't a fighter
Very cool
Yes, less dense air produces less lift, but the bigger problem is that it also causes the engine to produce less power. Less power means you go slower, which means even less air through the engine, which means less power, which means you go slower.... and so on. Until inevitably there is not enough power to keep the plane in the air.
The title should be " the maximum altitude fighter jet PILOT can reach"
MIG-25 in the corner: let the kids play
If you tied a Cessna to a balloon in such a way that would allow you to have the throttle wide open and you wore a space suit here is what will happen. You’d have to adjust the fuel/air mixture to a leaner setting to keep the gas/air mixture proportional. As a result your rpms will gradually drop. Eventually there wouldn’t be even enough breathable air to keep the engine turning and it would idle on the edge of a stall until finally the propeller stops entirely. You could release the plane and as you get down to denser air you could then finally start the engine again and land the aircraft safely with full power again.
They can't get lift beyond max altitudes due to air density issues, but if they switch to rocket fuel they can continue to ascend (but fighter jets don't use rocket fuel). Pilots in fighter jets use liquid oxygen tanks or LOX, not bleed air from engines at high altitudes, so they can still breathe and perform.
The Mig25 Foxbat was one of the few aircrafts across the globe that could reach 90000ft.
50-60k Ft? However atleast two aircraft that I know of went well above that on a regular basis, the U-2 & SR -71 oh and the A-12 and BTW all Kelly Johnson aircraft! That absolutely says something about the man and his men & women that worked along side him!
Thats why the guys that flew the SR71 were always wearing space suits
The highest ever altitude reached was done by the MiG-E266M at an astonishing altitude of 123,523ft.
USAF Major Robert W. Smith, flying F-104A 56-0756, set an unofficial world altitude record of 118,860 ft (36,230 m) on 15 November 1963, and on 6 December 1963 he flew the same aircraft to another unofficial altitude record of 120,800 ft (36,800 m).
Yeah I think it has more to do with the lack of oxygen at higher altitude which the engines need to operate. This is the main reason rockets don’t use traditional combustion engines that rely on the oxygen in the air to function properly.
A rocket engine also needs oxygen to function.
But the oxygen is simply just mixed into the fuel.
How magnificent
LOL! If that was the case, you could solve it simply by having a relatively small oxygen storage for the time the jet is over the critical altitude for the pilot. The one thing you cannot solve with jet engine (as opposed to rocket engine, where oxidant is liquid or solid) is the oxygen for burning the fuel!
"The maximum altitude depends on the type of aircraft" well thank you for stating the obvious.
The F15 that shot down an Satellite in space 👀
You can fly at high altitudes as long as you are going fast enough for enough airflow for the engines
Its one reason why scramjet technology works more efficiently at super high altitudes
Mig31 is record holder of all time 🇷🇺💪🏻💪🏻
Like they landed on moon 60 years ago but today in 2023 they can't find a jet goes too high
In 1959, the F-4 flew above 98,000 feet
Pilots usually can wear pressure suits and have breathing oxygen for such conditions, and someone already mentioned, it’s not a lack of oxygen, it’s a lack of pressure that makes it impossible to get oxygen into the lungs.
During WW2 there were propeller driven aircraft that were amazing for altitude
The F22 can exceed 60,000 feet.
The main problem is that THE F22 PILOT DOES NOT WEAR A PRESSURE SUIT.
He isn’t a U2 pilot or SR71 pilot.
Pressure suit only required in non-pressurized cockpit.
russian pilot: hold my vodka
The English Electric Lightning was recorded as reaching 88,000 feet, and had to stop the climb because the pilot wasn't wearing a 'g' suit. This happened in 1984. Recorded fact.
Ultimately, it's not the lack of oxygen or lift, since any jet could be pressurized or make a parabolic flight, but rather that in insufficient air density the aircraft would become uncontrollable and potentially unrecoverable.
Fighters carry their own oxygen. The alt is limited because there is not enough O2 for the engine.
The record about which I had read was in 1976, a McDonnell Douglas F-15A Eagle USAF Test Aircraft exceeded 104,000 feet.
