    Jet-powered aircraft are so central to our modern world that we hardly give them a second thought. However, like many things we take for granted, they have their origins in warfare. We plan to cover many other wartime inventions on this channel, but what's your favourite?

      The development of IFF (Identification, friend or foe) was an important yet massively overlooked wartime invention, saving countless airmen from friendly fire. The British development of the Perfectos device which allowed their night-fighters to hack German aircraft's IFF and hunt them down also makes for an interesting story.

      Radar, hands down. Radar completely changed the world in ways that make most of the other wartime inventions comparatively insignificant. It's even in bathroom faucets these days. Allied progress in Radar was simply astounding and formed the basis of the entire modern electronics industry. And the great friendly rivalries between the various US and UK research programs all vying to one-up each other while not losing sight of the main goal makes for some interesting stories.

    Chris from Military Aviation History channel has researched the infamous Me 262 demonstration. He concluded there is something of a myth about it. After all, the 262 was ready for service six months later (the demo was in November 1943, not August). In fact, all German fighters were stressed to carry bombs. The delays were down to difficulties with engine manufacture..

      @@frenzalrhomb6919the main point here is that Whittle’s jet engine idea was paused while more tested ideas where made by the 1,000. The Gloster Meteor flew in 1943 and was in service with 616 squadron by July 1944. There was never a real chance for Germany to jump ahead. In 1943 speed trials showed that Spitfires could handle 800 kmh in a dive so yes the bombers might have been sitting ducks, but the idea of Garland that these early trials put them far beyond prop fighters is based on lack of knowledge of their enemy. The maximum speed recorded for a Spitfire in 1944 was mach 0.92 (1,000kmh) btw, though that did rip off the propeller and almost the wings, everything else landed safely (by gliding).

    • @_ArsNova
      @_ArsNova Год назад +7

      I haven't seen this video, but agree with the conclusion. German fighter aircraft were under increasing pressure to adopt bomb payloads as the war progressed. Bombers were being lost, the Ju 87 was aging, the new ground attack/tactical bomber (Me 210) was plagued with design trouble. This is what let to the Bf 110 and Fw 190 being increasingly used in the fighter-bomber role, and pressure placed on engineers to make newer airframes capable of tactical bombing. The Me 262's production bottleneck was always engine procurement.

    It’s a myth that the inclusion of two hard points for bombs delayed the introduction of the ME262A, the main reason was the availability of reliable engines. The short supply of engine manufacture caused this, and their inherently unreliable status caused the biggest delays. The British design was a radial jet engine that didn’t need as much high temperature alloys as the axial flow type that the Germans used. The German Jumo 004 engine life was typically only 10 hours. Whereas the Gloster meteors Rolls-Royce RB.23 Welland engine was 180 hours! Whittle knew that an axial flow engine had some advantages, but life time and reliability were not as good at that time.

    While the Heinkel He 178 and the Gloster E.28/39 are often credited as the world's first jet-powered aircraft, there's a lesser-known contender that deserves mention. In Italy, Secondo Campini, an Italian engineer, developed an experimental jet-powered aircraft called the Campini Caproni CC.2 in the late 1930s. What makes this airplane particularly interesting is that it used a unique type of jet propulsion known as a "thermojet" or "jet engine with a heating chamber." Instead of the traditional jet engine design, which relied on exhaust gases for propulsion, the thermojet design used a piston engine to compress incoming air, heat it in a combustion chamber, and then expel it at high speed through a nozzle.

    • @WorldWarTwo

    The negative aspect of bomb carrying capacity on the development time of the ME-262 is grossly overstated. At the time, fighter aircraft were more and more used to drop smaller bombs in a tactical ground support role. It was thus a logical question to insure that the new jet fighter would be able to provide such a ground support role also. For a specific bomber role, the Arado234 was in development. The only limiting factor that a jet bomber request could have had was the limited supply of the jet engine that both of the mentioned aircraft shared.

    "... the maiden flight of one of the first jet planes in the world, the German made He-178..."
    The Heinkel He-178 was the first aircraft designed to be powered by a gas turbine
    It was powered by Hans von Ohain's Heinkel-Hirth HeS-3, the first gas turbine to be the sole power plant of any aircraft.
    It flew for the first time on 27 August 1939, before any other aircraft powered only be jet propulsion.
    It's first flight was followed by that of the Heinkel He-280 jet fighter (30 March 1941) and the British Gloster E.28/39 (15 May 1941)

    With the way the story often gets told (visionary inventors ignored by stuffy higher-ups), I do wonder what might have happened had either main country here gone 'all in' from the first instance. Would jet aircraft have been the wonder-weapons to win the war early, or would difficulty in pilot training and logistics (after all, you can't reuse any existing factory tooling or manufacturing expertise) have meant ultimately less success than sticking with piston power for as long as they did?

      That is indeed one of the great "what ifs" of the war. My opinion is, it would have given Germany a tactical advantage, but a small and fleeting one. By the time the first 262 squadrons were ready for action, France had already been invaded and Germany's overall material situation was in marginal and progressively worse shape. In the end, the allies still would have won in the same way, by essentially overwhelming Germany with men and material, it just maybe would have taken a little longer.

    A jet engine is an internal combustion engine. The definition of an IC engine is to use the fuel and the air mixture themselves to generate power (compared with the steam engine, which uses an external source i.e. water to channel the energy to generate power. Which is an external combustion engine).
    A jet engine has all the processes a piston engine has. But it is separated into 4 different components (compressor, combustor, turbine and exhaust) to perform them simultaneously, rather than doing them in the same chamber one after the other as in a piston engine.

      On a minor level, wrong fuel/air mix could cause hot spots in the combustion chamber and severely shortens the lifespan or even burns out the turbine.

    Many people who ask “why didn’t the Allies in WWII jump at the chance to use jets?” tend to ignore the complexities of making major changes like that during a war. All the Boring But Important stuff would be affected: production lines would have had to be re-tooled, workers re-trained, supply chains altered, and raw materials reallocated. Pilots would have had to be re-trained and even after their basic training would lack experience with the new planes. Mechanics and support crews, just as important to flying as the pilots, would also need complete re-training. Of course I'm not denying that it's possible to do that, there are many examples of rapid technological change during the war; but given that they were doing fine without them, the Allies correctly saw jets as something that would be important in a future war, not the current one.

    In Germany and the UK the internal politics of the air ministries held up jet development. Unknown to Whittle there was another gas turbine project underway in the UK in the hands of A A Griffith. Griffith was an engineering scientist of such great reputation that he was asked for an opinion on Whittle's simple design which he rejected as not able to produce enough thrust. Whittle was completely unaware of A A Griffith's involvement. There were other delays in the Whittle engine program particularly the squabble between Whittle and Rover.

      This was in the early 1930s though. There are two things about Griffith: (1) He had earned the respect. He was the country's leading expert on turbines and he, not Whittle, had worked out most of the mathematical theory of a turbojet; and (2) he was actually right at the time. There were no alloys that could stand the temperatures at the turbine inlet in Whittle's design. But Waspalloy, which could, appeared just a few years later - it was the metallurgists, not the engineers, that made the critical breakthrough.

    While in the Army, I studied German at the Defense Language Institute in Monterey, CA in 1974. One of our teachers was one of the a chief aircraft designer in the Air Minstry in Berlin, during the war, and had to meet Hitler daily towards the end of the war. He said that they had tried to convince Hitler that it was better suited as a bomber interceptor. They even had Hanna Reitsch try to convince Hitler, but he was adamant. Towards the final months of the war, he said that no one countered anything Hitler said or you could disappear. He escaped Berlin from the roof of the Air Minstry Building, which was not bombed during the war and still stands today, in an experimental one-man helicopter in the middle of the night. He basically flew from one roof top to the next to avoid all of Russian night fighters that filled the sky. He finally reached the British lines and was interrogated by two British officers, who asked him which planes he had worked on. He answered - ".... mainly the jet aircraft". They then asked him, "What's a jet?" He explained and they said that he was obviously lying, because there's "....no such thing as a plane that can fly without propellers!" This news was so top secret that the only people who knew about jets were Allied bomber crews and fighter pilots. This was later confirmed, by an old friend who was the Flight Engineer/Top Turret Gunner on a B17. He said that he was in the turret one day and saw a dot in the sky, obviously a German fighter. As he turned his guns to fire he thought he had plenty of time, when all of a sudden the jet flew right over the bomber, barely missing them. The jet pilot had miscalculated his attack, but what shocked my friend was the incredible speed. He had thought that he had plenty of time to turn his guns to fire, but the ME262 was on him in flash. Then there was the fact that there were NO propellers. Nobody in his crew who saw it could believe their eyes! When they returned to their base, they were ordered during debriefing not to discuss this with anyone or face a courts martial and time in the brig. He said that he had almost messed himself when the jet first flew by, but was happy just to be alive. ME262 jets then started to shoot B17 bombers out of the sky in increasing numbers. For the life of me, I can't remember the German teacher's name, but my friend, Alan Morton, later worked for NASA and met Werner von Braun in person numerous times.

    • @renegadeleader1
      @renegadeleader1 Год назад +2

      Straight wings provide better lift at lower speeds versus increased drag at higher speeds. The reduced drag of a swept wing would not have helped the P-51 or Tempest at the speeds they operated at, and would have actually hurt their performance. It was only the advent of jet aircraft with speeds reach 500-600mph+ range that made the swept wing a viable option.
      As for the ME-262's swept wing it wasn't developed with aerodynamics in mind, rather instead it was done to maintain the aircraft's center of balance once the decision was made to shift the engines to the wings instead of the fuselage.
      It was only during late and post war testing that the true effect of swept wings on highspeed aircraft became understood and were integrated into designs like the F-86 Sabre which began life in 1944 as a straight wing design spun off of the FJ-1 Fury, which itself came from an attempt to create a jet engine variant of the P-51.

      Are you kidding? The 262 was undeveloped rushed together desperate junk. *The Meteor was a proper fully developed jet plane, not a thrown together desperate effort as the me262 was.* The me262 fuselage was similar to a piston plane with the pilot over the wings obscuring downward vision, while the Meteor was a proper new design fuselage specifically for jet fighters with a forward of the wings pilot position with superior vision, as we see today. The cockpit was very quiet. The high tail was not to impede the rear jet thrust. The partial sweptback wings of the me262 were to move the engines further back for better weight distribution, not for aerodynamic reasons as is thought the case. The 262 balancing problem would be exasperated when firing the guns as the weight of the bullets exiting suddenly made the the air-frame unbalanced.
      The Meteor was deliberately designed to have an air-frame of known qualities, as if there were problems it would be down to the jet engine not the airframe. In WW2 British went for the centrifugal engine design as it was quicker to get operational reliably. In 1943 the Meteor ran with axial-flow engines. The first proper and reliable _axial flow_ engine was the RR Avon in 1950.

    The Gloster Meteor did have it's World War II uses. They intercepted many V-1 flying bombs for example which it's high speed allowed it to do much more easily that it's piston powered contemporaries, although they did have trouble with the guns jamming but that was not exactly the fault of the jet engines themselves. However the Meteor and it's technology were so closely guarded by the RAF that a directive was made prohibiting it's deployment outside of the British isles so there was no way a Meteor could fall into enemy hands whether by crashing or being shot down behind their lines.
    Adolf Galland it's also worth noting flew with the Argentinian air force after the war too and they were equipped with Gloster Meteors which he got to fly himself. To paraphrase his opinion on the aircraft, the Me262 was a better aircraft but the British engines were far superior, probably due to war time shortages faced by the designers of the German engines in the 262.

    The Me262 had swept wings. Swept wings may seem very common nowadays, as present on every major commercial jet around the world. But it was a revolutionary innovation in WW2.
    An aircraft can only fly so fast before it reaches critical Mach number. Normally on an aircraft with unswept wings, that's 60% of the speed of sound. By then the faster airflow on the wing's upper surface reaches the speed of sound, and start forming shockwaves and vastly increases drag for the aircraft and makes it very difficult to go faster.
    When air hits a swept wing, it passes over the wing at an angle. The velocity component of the flow parallel to the chord is reduced (rather than 100% as on an unswept wing). So even with the same airspeed, a swept wing aircraft would have lower chordwise airflow speed -- the speed that goes supersonic and create shockwaves.
    Hence an Me262 could reach critical Mach at 70% the speed of sound, compared with 60% as with most unswept wing aircraft of its time.
    Nowadays airliners so a the "supercritical aerofoil" wing profile -- with a flat top and curvy bottom, to further delay the critical Mach to up to 90% speed of sound.

    The Mk XIV Spitfire was only about 34 mph slower than the 262 in level flight and faster in a dive. The 262 only went to around 450 mph, or the pilot was in trouble. The makers said it went to 550 mph, no one else reached that. 262 pilots were told not to go over 450 mph as stability was affected.

    • @wanderschlosser1857
      @wanderschlosser1857 9 месяцев назад

      I highly doubt that. The 262 became tricky above Mach 0.8 and uncontrollable above 0.86. As we know the Spitfire indeed could reach higher Mach numbers in a steep and long dive becoming uncontrollable closer to 0.9. Which wasn't really a property with a lot of use in a practical combat engagement against a 262. In level flight no prop driven fighter came anywhere near a 262. The dive properties only helped in a surprise attack from above to get close to a 262. Out of a high speed level flight a 262 would accelerate much faster to a higher dive speed than a Spit. Even if a Spit could technically reach a higher speed in a dive, until then the 262 would be long gone. And German jet pilots flew certainly much faster than 450 mph in level flights when required without difficulties in controllability. 800-850 kph or 500-530mph could be reached in level flight and were far below the max Mach No., especially below 8000 m altitude (thicker air = lower Mach No.for equal above ground speeds). Spits and Mustangs wouldn't reach such speeds above that altitude anyway because they would have to dive quite a bit first to get to such speeds.

    There's an almost forgotten moment in the history of jet engine design that happened in Spain just before the Spanish Civil War.
    Military engineer Virgilio Leret had a prototype of the jet engine by 1935. He was killed by the fascists in the early stages of the fascist coup that lead to the war. His wife, Carlota O'Neill, was able to smuggle the designs to British commander James Dickson in 1940, hoping it would help the allied war effort against the nazis.

    *Jet facts:*
    • To a thermodynamicist, jets aren't too different from piston engines. Both have a thermodynamic cycle (suck, squeeze, bang, blow) in which air is compressed, fuel injected and ignited, and the resulting high-pressure combusted gas pushes the engine along. Indeed, jet engines have a compression ratio, as do car engines, and just like in cars, the higher it is the more efficient.
    • The bypass ratio is the proportion of the air accelerated by the engine which bypasses the compressor. Since the thrust increases only linearly with the speed added to the air by the engine, but the energy needed to do so increases quadratically, it's more efficient to increase the thrust by accelerating more air than by accelerating the same amount of air to a greater speed. So a higher bypass ratio is more efficient. However, it is inappropriate in supersonic jets, and it requires bigger turbine blades which can withstand greater centrifugal forces/stress. This is why old jets and supersonic jet engines are thinner than modern civilian jets.
    • Because the turbine and compressor blades have to be so strong (with high temperatures and pressures, plus centrifugal forces), one of the main limitations to jet design is materials science. Nowadays, each blade is typically made from a single metal crystal/grain.
    • Civilian jet engines are often rented out nowadays, instead of being just another part bought with the plane.

      @@vksasdgaming9472 Of course. Still, by following a volume of air through either engine as it is compressed, combusted and used to push the engine along, you can see a thermodynamic cycle which is fundamentally quite similar. You'd typically draw this as graph showing cycles of pressure and volume or temperature and entropy, and the graphs would look fairly similar (albeit stretched differently) in both cases.

    Noteworthy is the somewhat unintuitive assessment of production cost and time: It was less than a third of the cost of the Junkers 213 piston engine and needed only 375 man hours to manufacture as opposed to 1400. I call this unintuitive since this was a state of the art prototype still and piston engines were proven and optimized technology. Had development started only 2 years earlier it's likely the germans would have pumped out a lot of these engines. As mentioned their fuel requirements are also lower. So far jet engines have been converted to almost any fuel, the only thing that didn't quite work out is coal dust due to the ash content eroding the fan blades.

    I believe the great appeal of jet engines was they ran on kerosene and offered at the time the same performance of piston engines which ran on highly refined distillates. Logistically that is a team come true and having worked around 130 octane Avgas its volatility is always in the back of your mind.
