Die deutsche Luftfahrt Industrie war vor dem Krieg enorm kreativ! Ich kannte schon einige Projekte, aber dieses noch nicht. Herzlichen Dank für diesen Bericht!
@@georgebarnes8163 No, they had a system to make them drop down at a certain time, which is at least questionable in its accuracy and reliability, but it IS an early guidance system. It was very vulnerable though, tipping the V1´s wings caused them to fall already, a method the pilots defending Britain due to them shooting the V1 caused mid-air explosions easily damaging their fighters. An early cruise missile is a good definition for the Vergeltungswaffe, especially when you take the V2 into context as well.
@@georgebarnes8163 you might want to read up on that. Per Wikipedia: The V-1 guidance system used a simple autopilot developed by Askania in Berlin to regulate altitude and airspeed.[15] A pair of gyroscopes controlled yaw and pitch, while azimuth was maintained by a magnetic compass. Altitude was maintained by a barometric device. Two spherical tanks contained compressed air at 6.2 megapascals (900 psi), that drove the gyros, operated the pneumatic servomotors controlling the rudder and elevator, and pressurized the fuel system. The magnetic compass was located near the front of the V-1, within a wooden sphere. Shortly before launch, the V-1 was suspended inside the Compass Swinging Building (Richthaus). There the compass was corrected for magnetic variance and magnetic deviation. The RLM at first planned to use a radio control system with the V-1 for precision attacks, but the government decided instead to use the missile against London. Some flying bombs were equipped with a basic radio transmitter operating in the range of 340-450 kHz. Once over the channel, the radio would be switched on by the vane counter, and a 120-metre (400 ft) aerial deployed. A coded Morse signal, unique to each V-1 site, transmitted the route, and impact zone calculated once the radio stopped transmitting. An odometer driven by a vane anemometer on the nose determined when the target area had been reached, accurate enough for area bombing. Before launch, it was set to count backwards from a value that would reach zero upon arrival at the target in the prevailing wind conditions. As the missile flew, the airflow turned the propeller, and every 30 rotations of the propeller counted down one number on the odometer. This odometer triggered the arming of the warhead after about 60 km (37 mi). When the count reached zero, two detonating bolts were fired. Two spoilers on the elevator were released, the linkage between the elevator and servo was jammed, and a guillotine device cut off the control hoses to the rudder servo, setting the rudder in neutral. These actions put the V-1 into a steep dive. While this was originally intended to be a power dive, in practice the dive caused the fuel flow to cease, which stopped the engine. The sudden silence after the buzzing alerted people under the flight path to the impending impact.
This is correct. The guidance was iffy and subject to local intelligence, but it was absolutely the first. It was horribly inefficient, but that's got nothing to do with timing.
@@georgebarnes8163 had gyroscopic guidance with predetermined distancing programmed that was determined by aerial intelligence which in the 1940's would not have been the most reliable
Pulse jets are an amazing phenomena. See Colin Furz's pulse jet build. I knew that vibration would be a problem with the pulse jet but resonance vibration between two of them had not occurred to me. Good episode.
You have my humble thanks for this video. I was unaware of this aircraft. I will be watching your channel daily now as I just found you. I am pleased at what I have found so far. Again, please accept my compliments on the video and I look forward to reviewing all your videos!
I'm surprised that I've never heard of this project until now. Everyone knows about the ME-163 and the NE-262. How many folks knew about this plane before this video. Very interesting video.
I read of these as being a single design. The vibration problem is so new to me. A British TV series, Junk Heaps Challenge, had four men building a go kart fitted with their a copy of the engine. They were successful,
The resonant low frequency vibration would incapacitate a pilot very quickly. Having worked on the flight deck of an aircraft carrier, when an S-3 Viking had a hung start, the ground crew would suffer. Nausea and, uh, various other symptoms were horrible. Being strapped into an aircraft with 2 or 4 engines doing it non-stop could prove lethal.
I learned about this plane from buying the old Airfix Do 217+Me 328 Mistel kit back when I was a youngster. It is interesting that it is not featured almost in any WW2 aviation-themed books at all.
Fascinating stuff new to me, thanks. I'd never heard of manned pulse jets before, but as a musical instrument maker, I realized right away that they would have enormous problems with vibration and resonances. cheers from cool Vienna, Scott
Studio Ghibli’s Castle in the Sky showed a pulsejet-driven airplane, and seemed to show it operating on a spring-damper, presumably sparing the passengers some of the vibrations.
Detonation-based engines do exist in a more modern form.en.wikipedia.org/wiki/Pulse_detonation_engine. If you have a lot of small detonations very close together, then the effective thrust can be made to approximate a continuous push. Of course, this is not an option for a WW2-era pulsejet. If you have more than one engine and they are off-centreline, then - since there is no realistic way to synchronise the engines - they would put tremendous stress on the airframe and cause heavy vibration as it was pushed rapidly from one side to another by unbalanced thrust.
@@worldofwarbirds There was an american plane, the Screamjet i think it was called, that did produce sounds making people around the plane sick too, it had a supersonic propeller, forgot the proper designation though.
it’s 3 times worse, noise and vibration. You can’t pilot something like that. It also made for the impossible use of instruments that were so sensitive in those days.
Actually Russia built a twin pulsejet prototype fighter or 2 1st, back in 1940. It was a twin boom fighter like the P38, which also had all the guns & cannons in the nose, together with a nosewheel. However each boom was made up of a pulsejet in the middle of each boom, with a V12 engine in the middle of the aircraft, behind the pilot & a pusher propellor. It was designed to use the traditional aero engine & pusher prop for normal flight, with the option to uses the pulsejets for climbing &/or combat. Problem was Barbarossa got in the way as did the policy of transferring factories East of the Urals, plus another policy of cancelling all projects that couldn’t be completed with 3 months
It always astonishes me how just how many of the warring nations were willing to try just about anything to get the edge. Of course, many of the ideas were crackers, but some were war winners!
@@worldofwarbirds I always strikes me that a lot of the crazy Wunderwaffe ideas came about from a strong desire of the engineers to not be sent to the Eastern Front.
The Fieseler Fi-103 a.k.a. "V-1" was a cruise missile. The precursor of cruise missiles was the 1917 U.S. experimental "Kettering Aerial Torpedo" a.k.a. "Bug".
Good explanation of why vibration ruled out its effective use as a piloted plane. Would have been interesting to hear what sort of fuel efficiency it achieves compared with conventional engines of similar power - just how much does this limit the range. The pulse jet concept appears to have been revived in Ukraine as a fast drone for one way use against Russian airfields and supply depots.
“Segelflug” doesn’t mean “sail plane” in English. That’s just the literal translation. What it really means is “gliding”. Therefore, that’s the German Institute for Glider Research.
There are lots of RUclips videos of remote controlled model airplanes powered by pulsejets. They are loud! It's funny to watch their owners trying to get them started. Some use a landscaping blower. The airplanes sure go fast but not faster than the speed of sound, so piloting a plane powered by a pulsejet would sure give you a headache pretty fast.
It's still astonishing to think that Germany was almost 2 Decades ahead of the Allies in Technology. Some major development in early computing was achieved as well but Hitler showed no interest. One of the Engineers, Conrad Zuse would see his successes after the War; in America.
The Japanese Navy didn't like the Kamikaze idea either, originally. It took the catastrophe of the Philippine Sea campaign in June 1944 to convince the admirals that conventional attack was a hopeless tactic against the Allied navies.
The MXY-7 Ohka wasn’t originally intended to be a suicide weapon. There were several infrared seeker and radio guidance projects, and the Japanese had been given plans for the Henschel HS-293. There was the Kawasaki Ki-148 and the Ke-Go. Unfortunately for them, the projects hadn’t progressed satisfactorily and at they changed the design of the MXY-7 to include a cockpit and controls for a Kamikaze pilot rather than a guidance system.
@@The_Conspiracy_Analyst - That's interesting. I have never learned much about the Ohka, and of course, much of the evidence was likely destroyed during 1945, or is stuck in the National Archives.
The first kamikaze wave happened DURING that battle. Literally the day after the embarassing standoff of the main Japanese battleship fleet by the puny Taffy 3 force. One of the US escort carriers that survived that ordeal was destroyed by a kamikaze that day.
I wonder if the Me 328's engine had a throttle. It would be possible to fly around at just one power setting, but it would put the aircraft at a great disadvantage against anything else.
I've often wondered why there were so few experiments using ramjets. I also wonder why no one tried using a ramjet as a pulsejet with the one way valve over the intake of a ramjet to allow it to function at low speed and then retract the valve and shut off the spark ignition when it was up to ramjet operating speed.
I was on vacation and used a public bus with ICE for 40 minutes. So much noise and vibration. I wondered how the bus driver can bear this the whole day.
Buzz bomb meh in thinking could be considered and i believe it is so the first cruise missile although missiles are guided as rockets aren't so i suppose would make it a cruise rocket however wasn't rocket powered
Pulse jet 'Economy, high thrust and low weight'. Economy - in construction, yes. In fuel consumption absolutely not - much of the fuel gets tossed out the back and burns as a trail of fire. High thrust - only at low altitude, as air pressure decreases, so does efficiency. Low weight - yes.
I personally LOVE the idea of a submersible aircraft carrier. The logistics of such a thing in WWII are difficult at best. Ive heard of the I-400's but they used piston driven strike craft. This using pulse jet is a new concept to me!. Love it! Ok so we know we sunk all the 400's to prevent Russian investigation. Id bet the US has some form of submersible drone carrier now. If they don't they are fools. We could launch them now like we do missiles underwater ejecting with air breaching the surface to be ignighted for launch. Id suspect the craft would have to rise to accept returning craft.
Given the quality of your research and presentation, you should produce videos on V1's or anything you want. I'll be watching. Keep up the great work. Thank you!
I think the plan was to have the pilot cut the fuel and bail out just before reaching the target and having the "missile" glide in to the target so it wasn't really a suicide mission, just a near suicide mission and considering that during the cold war, one of the Canadian mission plans was to have a fighter carry a single nuclear bomb to a target and then have the pilot bail out at a safe distance to spend the rest of the war hiding, the concept really isn't as shocking as the kamikaze pilots. As to the two or more pulse jets firing at different intervals causing dangerous resonance that endangered the plane's structure, I'm surprised they didn't mechanically or electrically synchronize the air inlet valves or have multiple combustion chambers sequencing the valves so the explosions smoothed out much as a multi cylinder combustion engine does with the explosions especially as the company's history involved car piston engines... It's not as if they didn't already have expertise with timing chains and distributors to synchronize the valves and spark ignitions of a number of combustion chambers into a controlled order or have the expertise in different lengths of pipes in an exhaust manifold to merge the outflow from multiple explosions into a smoother exhaust...
And the horrific inefficiency. Much of the fuel is thrown out the back and burns outside the engine, generating no useful thrust. This the trail of fire that can be seen behind V1s in flight.
How fast was it? With 2 or even 4 pulse jets it could be significantly faster than a V1. Despite the noise and vibration it potentially would have been very successful as a kamikaze against shipping. Troop ships off Normandy for example (assuming they still had some true believer pilots).
Some days ago i wondered why i have never seen a twin pulse jet aircraft, then this video pops up Some of the issues could probably be at least partially mitigated, but the power part would be a real issue without a compressor attached, and without power and speed you would have a pretty poor fighter. Still my questions have been answered and i didn't even need to look it up myself =) do you have a video on the coal powered ram-jet Lippish made?
Hence operation LUSTY: "Luftwaffe Secret Technology" (my favourite operational codename!) It was the United States' effort to evaluate German aeronautical technology during and after World War II.
@@GBOAC honestly i dont know exactly why, i do know the ones germany built didnt have a throttle, and the home built versions, ive nvr seen throttle, the way the engine works is similar to a solid rocket motor
@@clarkbutler there's a big difference between it being impossible and just very hard. it was the latter, so for the V1 they simply didn't bother but for the Me328 they did manage to implement a very crude throttling that allowed a ballpark range of 20-30% reduction before the engine would cut out. obviously greatly hindering its practical use but it was not equivalent to a solid rocket booster by all means, not to mention those can't be stopped and started while pulsejet obviously could (with difficulty nonetheless but still possible).
About the problem of reduced power at higher altitude, could it have been useful in close air support? And would having the 2 pulsejets stacked one above the fuselage and one below have improved the thrust syncing?
Crazy to think had the germans developed missles and not flak units or bombers with flak cannon attached and all b17 smoked the war would have stopped... Minus maybe russians overrunning on ground?
The advantage of the V1-derived Fi103 over the Me328 in the suicide role is obvious. It solves the two-pulsejet vibration problem, and it's already designed to hold a big warhead. Conversely, it's a terrible airplane and useless as a fighter. The British later calculated that the production cost of the V1 using slave labor was about 290 pounds sterling. The Fi103 would cost more, but that production cost tells us that it was a far smaller drain on resources than any properly-designed manned aircraft. The fundamental problem is shared with the Japanese. You can build more of them, but you can't train enough pilots who can crash into a target accurately at those speeds.
I saw heard in your video you respond to every comment, what is your opinion on the new quantitive tightening measures instituted by the Japanese central bank in an attempt to strengthen the yen?
The Bank of Japan (BOJ) has recently initiated quantitative tightening (QT) measures, marking a shift from its historically ultra-loose monetary policy. These changes aim to strengthen the yen and address inflation dynamics that have shifted in Japan after decades of near-zero inflation. The BOJ raised its short-term interest rates to slightly above zero for the first time in years, signaling a departure from its negative interest rate policy. This move is designed to address persistent yen weakness, which has raised import costs and contributed to inflationary pressures. Japan has faced challenges in balancing inflation targeting with economic growth, as inflation rates are still approaching, but not fully anchored at, the 2% target. The BOJ’s tightening measures aim to create a more stable environment for the yen and address structural changes in inflation and wage dynamics The tightening strategy also reflects growing concerns about capital outflows and currency volatility as other central banks, such as the Federal Reserve and European Central Bank, have maintained higher rates. By increasing its policy rates and scaling back its asset purchases, the BOJ seeks to align with global monetary trends while safeguarding domestic economic recovery However, the policy carries risks. Tighter monetary conditions could dampen domestic demand, which has shown moderate growth, and increase the cost of borrowing, potentially affecting corporate investments and household spending. The BOJ's approach suggests cautious optimism, with further adjustments likely dependent on inflation stability and global economic conditions
Thanks for the critique. AI is a new toy/tool for me and I’m still figuring out if, how and where to use it. The narration is all me though, as can be ascertained when I goof up!
@@worldofwarbirds But it would be easy to replace the reed valves with a rotating disc, that has a hole that uncovers each tube in turn. If the pulse from each pulse jet overlapped with the previous, and subsequent pulses, the vibration and noise would be significantly lower, compounded with the affect of having 6 small pulses, instead of one really big pulse, it would be a more more practical solution.
Really really interesting. Thank you very much. But as interesting as the aircraft itself is, it also got me thinking: did anyone during The Second World War ever consider towing standard fighters behind bombers during raids? After all, one of the Luftwaffe's big problems during The Battle of Britain was the range of it's escort fighters. Would there have been some way to attach a Bf. 109 to the back of a bomber, have it take of under it's own power, then once cruising altitude had been reached, switch off the engine and glide the rest of the way until the combat area was reached? I wonder if this was ever considered.
Not sure about the war, but the US played with the idea a few years after with an aircraft dubbed the "Goblin" that was supposed to be carried by bombers and dropped to provide air defense, before being picked up again for the flight home. The project was canned because the aircraft wasn't very good at being a fighter, and successfully reattaching itself to the mothership proved difficult and dangerous.
If the Luftwaffe had asked the Japanese they may have got some Zero's. Zero's could easily defeat the Spitfire (as proven in the battles over Northern Australia) and had around 8 hours endurance.
Was the V-1 an aircraft or a weapon? You asked the question. I'll take a stab at it, based on a little knowledge and lots more ignorance. (grin) It all depends on whether you consider a Tomahawk cruise missile an aircraft or not. The V-1 was on of the first successful cruise missiles. It wasn't especially accurate, but it was accurate enought to hit a city at range, which was good enough for the Germans' purposes. I don't consider it to be any more of an aircraft than any other long range self-guided missile. But then, I'm just a grumpy old fart. Love your channel. Keep it up.
Pulse jets really can’t handle any g-forces, fuel flow gets interrupted by even moderate g-forces, and any fuel interruption means engine cut off. So, a totally useless idea.
Your explanation of a pulsejet engine is way off, and inaccurate. you are describing two types of engines as one type. Your first diagram shows a VALVELESS pulse jet engine (2:18) then you switch to a PULSE Jet engine.
Thanks for pointing that out. I published an errata on the description and on the screen at the image. RUclips does not allow editing after publishing.
I cant help thinking What junk! But I bet using todays tech for perfect ignition synch? it could work vastly better? Lots of old designs can work much better with todays tech,,,,like old racing vehicles getting modern tires brakes and suspension for example could run circles around stuff of their day
😊 putting 2 jets close together😊 reduces the😊 combined power output to😊less than one.....😊,... a little disappointing😊and the reason why it😊 and a😊 failed anti-aircraft double pulsejet missile project by Zeppelin 😊 also failed😊
The AI images really don't contribute anything to this video. I wish creators would stop using them like this. You could use all of your other images like one second longer each and you'd more than make up the time.
@@worldofwarbirds as i said i had to stop. that bothered me because i really wanted to learn about a plane i knew very little about. but when you know some of whats presented is fake how can you trust the rest?
You can trust because I clearly label any instance of its use. Also, I haven't been able to use it for the actual aircraft yet, as AI so far can't tell the difference between a Me109 and a Lanc. But its quite good at: " black-and-white image of 1930s German technicians brainstorming futuristic aircraft ideas on a blackboard"

I would class the V1 as the world's first cruise missile

Supposedly the harmonizing vibrations could actually make the pilot ill.

That was a testplane to improve the V1, no computerised probes or detectors at that time.
It was a prototype but was banned by Hitler.
V1 was flown in a piloted version by Hannah … She'd fly almost ANYTHING. So yes, it's a warbird.
Yes! She was an amazing pilot.
Many thanks. I love learning about subjects totally new to me.

Pulsejets generate major vibrations that cannot be synchronised. Two jets were destructive and unworkable. So, yeah. Stupid idea.
I'm sure you could put dampers
@@The_Conspiracy_Analyst Well, maybe they tried and maybe they didn't. But the *designers* decided it was unworkable after some test flights.

The Japanese Navy didn't like the Kamikaze idea either, originally. It took the catastrophe of the Philippine Sea campaign in June 1944 to convince the admirals that conventional attack was a hopeless tactic against the Allied navies.
The MXY-7 Ohka wasn’t originally intended to be a suicide weapon. There were several infrared seeker and radio guidance projects, and the Japanese had been given plans for the Henschel HS-293. There was the Kawasaki Ki-148 and the Ke-Go. Unfortunately for them, the projects hadn’t progressed satisfactorily and at they changed the design of the MXY-7 to include a cockpit and controls for a Kamikaze pilot rather than a guidance system.
@@The_Conspiracy_Analyst - That's interesting.
@@The_Conspiracy_Analyst - That's interesting. I have never learned much about the Ohka, and of course, much of the evidence was likely destroyed during 1945, or is stuck in the National Archives.
The first kamikaze wave happened DURING that battle. Literally the day after the embarassing standoff of the main Japanese battleship fleet by the puny Taffy 3 force. One of the US escort carriers that survived that ordeal was destroyed by a kamikaze that day.
I wonder if the Me 328's engine had a throttle. It would be possible to fly around at just one power setting, but it would put the aircraft at a great disadvantage against anything else.
I've often wondered why there were so few experiments using ramjets. I also wonder why no one tried using a ramjet as a pulsejet with the one way valve over the intake of a ramjet to allow it to function at low speed and then retract the valve and shut off the spark ignition when it was up to ramjet operating speed.
Actually I know very little about ramjets- something to look at in the future!
Thank you for showing this.,Idea solid booster rocket in a slightly redesigned Me-163 instead of licquid rocket engine?
The osolations reminds me of the bridge that shook it self apart.
I was going to say that the Bachem Ba 349 Natter was solid fuel, but I think had a liquid fuel sustainer…I’ll have to research it!!
I was on vacation and used a public bus with ICE for 40 minutes. So much noise and vibration. I wondered how the bus driver can bear this the whole day.
V1 was a crude cruise missle
Отличная работа 👍
"Storch" isn't prounced as "starch", but "Shtorkh"
Sorry!
Buzz bomb meh in thinking could be considered and i believe it is so the first cruise missile although missiles are guided as rockets aren't so i suppose would make it a cruise rocket however wasn't rocket powered
Pulse jet 'Economy, high thrust and low weight'. Economy - in construction, yes. In fuel consumption absolutely not - much of the fuel gets tossed out the back and burns as a trail of fire. High thrust - only at low altitude, as air pressure decreases, so does efficiency. Low weight - yes.
I personally LOVE the idea of a submersible aircraft carrier. The logistics of such a thing in WWII are difficult at best. Ive heard of the I-400's but they used piston driven strike craft. This using pulse jet is a new concept to me!. Love it! Ok so we know we sunk all the 400's to prevent Russian investigation. Id bet the US has some form of submersible drone carrier now. If they don't they are fools. We could launch them now like we do missiles underwater ejecting with air breaching the surface to be ignighted for launch. Id suspect the craft would have to rise to accept returning craft.
Oh this reminds me that I’ve GOT to do the Aichi M6A Seiran aircraft that was designed and built for the I-400!!
Very interesting. I seen aircraft I never hear or see before.
I’m glad you liked it!
Fine video !
Thank you very much!
Given the quality of your research and presentation, you should produce videos on V1's or anything you want. I'll be watching. Keep up the great work. Thank you!
Thanks so much!
I think the plan was to have the pilot cut the fuel and bail out just before reaching the target and having the "missile" glide in to the target so it wasn't really a suicide mission, just a near suicide mission and considering that during the cold war, one of the Canadian mission plans was to have a fighter carry a single nuclear bomb to a target and then have the pilot bail out at a safe distance to spend the rest of the war hiding, the concept really isn't as shocking as the kamikaze pilots.
As to the two or more pulse jets firing at different intervals causing dangerous resonance that endangered the plane's structure, I'm surprised they didn't mechanically or electrically synchronize the air inlet valves or have multiple combustion chambers sequencing the valves so the explosions smoothed out much as a multi cylinder combustion engine does with the explosions especially as the company's history involved car piston engines... It's not as if they didn't already have expertise with timing chains and distributors to synchronize the valves and spark ignitions of a number of combustion chambers into a controlled order or have the expertise in different lengths of pipes in an exhaust manifold to merge the outflow from multiple explosions into a smoother exhaust...
How aviation changed so much from 1907 to 1945. How incredible that the Germans really brought so much technology to teh forefront.
not a war bird. its a weapon in its entirety. the first "cruise missile"
It all comes down to the lack of thrust achievable from a pulsejet.
And the horrific inefficiency. Much of the fuel is thrown out the back and burns outside the engine, generating no useful thrust. This the trail of fire that can be seen behind V1s in flight.
That opening song gave me cadets ptsd
Ooops sorry about that!
How fast was it? With 2 or even 4 pulse jets it could be significantly faster than a V1.
Despite the noise and vibration it potentially would have been very successful as a kamikaze against shipping. Troop ships off Normandy for example (assuming they still had some true believer pilots).
Some days ago i wondered why i have never seen a twin pulse jet aircraft, then this video pops up
Some of the issues could probably be at least partially mitigated, but the power part would be a real issue without a compressor attached, and without power and speed you would have a pretty poor fighter.
Still my questions have been answered and i didn't even need to look it up myself =)
do you have a video on the coal powered ram-jet Lippish made?
Not yet!
So I guess that's why there were no multi-engine pulse bombs.. wouldn't want to resonate a payload or it's carriage.
Yes, I guess that is the case!
Not really a war bird, however a war drone🤔
A cruise missile?
3:45 Yes as there were versions with a pilot . 👍
The genius of the Germans is astounding: how they keep pushing the boundaries!! So far ahead of everyone else!
Hence operation LUSTY: "Luftwaffe Secret Technology" (my favourite operational codename!) It was the United States' effort to evaluate German aeronautical technology during and after World War II.
Ford.
what was the thrust of the argus pulse jet, and how would you throttle it, im pretty sure it cant be throttled
2.2 to 3.6 kN, why would you think you couldn't throttle them via fuel flow, like most engines?
@@GBOAC honestly i dont know exactly why, i do know the ones germany built didnt have a throttle, and the home built versions, ive nvr seen throttle, the way the engine works is similar to a solid rocket motor
@@clarkbutler there's a big difference between it being impossible and just very hard. it was the latter, so for the V1 they simply didn't bother but for the Me328 they did manage to implement a very crude throttling that allowed a ballpark range of 20-30% reduction before the engine would cut out. obviously greatly hindering its practical use but it was not equivalent to a solid rocket booster by all means, not to mention those can't be stopped and started while pulsejet obviously could (with difficulty nonetheless but still possible).
Hello, if you have pictures, dimensions, and more information about the Argus As 044, please send them to me.
Did you mean Argus As 014?
@worldofwarbirds No, I mean the Argus as 044, or rather the Paul Schmidt sr 500.
A note : German ch sound is no k! It is similar to the noise an angry cat makes.
Thank you. I have been working on my non-English pronunciation, but tbh languages are not my forté.
Better than the 'piloted V-1'.
V1 has wings so it flies like a bird. It was used in war. Sooooo!
About the problem of reduced power at higher altitude, could it have been useful in close air support?
And would having the 2 pulsejets stacked one above the fuselage and one below have improved the thrust syncing?
The thing was unflyable, so how does it get to do CAS?
I guess he just meant that it was “more flyable” at low levels
ty
The first X-craft.
After WW2 "wanted to talk to the American and Russian scientists, but couldn't speak German"
Crazy to think had the germans developed missles and not flak units or bombers with flak cannon attached and all b17 smoked the war would have stopped... Minus maybe russians overrunning on ground?
Silly idea Pulse jets feature Heavy fuel burns...basically run Only at one throttle openining and Are slower than a Turbine jet.
The V1 was the first long range missle. It wasn’t piloted so it wasn’t a War Bird. At least that’s my opinion.
Except for the piloted version (Fieseler Fi 103R Reichenberg)! I think it'll get an ep one day!
I love your chnnel🙂🙂
Thank you!
Great ! ❤
Thank you! 😊
The advantage of the V1-derived Fi103 over the Me328 in the suicide role is obvious. It solves the two-pulsejet vibration problem, and it's already designed to hold a big warhead. Conversely, it's a terrible airplane and useless as a fighter.
The British later calculated that the production cost of the V1 using slave labor was about 290 pounds sterling. The Fi103 would cost more, but that production cost tells us that it was a far smaller drain on resources than any properly-designed manned aircraft. The fundamental problem is shared with the Japanese. You can build more of them, but you can't train enough pilots who can crash into a target accurately at those speeds.
Very true observations.
I saw heard in your video you respond to every comment, what is your opinion on the new quantitive tightening measures instituted by the Japanese central bank in an attempt to strengthen the yen?
The Bank of Japan (BOJ) has recently initiated quantitative tightening (QT) measures, marking a shift from its historically ultra-loose monetary policy. These changes aim to strengthen the yen and address inflation dynamics that have shifted in Japan after decades of near-zero inflation.
The BOJ raised its short-term interest rates to slightly above zero for the first time in years, signaling a departure from its negative interest rate policy. This move is designed to address persistent yen weakness, which has raised import costs and contributed to inflationary pressures. Japan has faced challenges in balancing inflation targeting with economic growth, as inflation rates are still approaching, but not fully anchored at, the 2% target. The BOJ’s tightening measures aim to create a more stable environment for the yen and address structural changes in inflation and wage dynamics
The tightening strategy also reflects growing concerns about capital outflows and currency volatility as other central banks, such as the Federal Reserve and European Central Bank, have maintained higher rates. By increasing its policy rates and scaling back its asset purchases, the BOJ seeks to align with global monetary trends while safeguarding domestic economic recovery
However, the policy carries risks. Tighter monetary conditions could dampen domestic demand, which has shown moderate growth, and increase the cost of borrowing, potentially affecting corporate investments and household spending. The BOJ's approach suggests cautious optimism, with further adjustments likely dependent on inflation stability and global economic conditions
@ chat GPT ahh response
Haha
Sorry but your intake pipe pulsejet drawing is wrong. That is the valveless type, completely different.
Yes. I’ve realized that now! Thanks for pointing it out!
Yes. I have added a correction to the video and a disclaimer to the description. Thanks for pointing this out.
Some constructive cristism I think the Ai images detract and look out of place with the majority of rest of video. Is the narration also Ai?
Thanks for the critique. AI is a new toy/tool for me and I’m still figuring out if, how and where to use it. The narration is all me though, as can be ascertained when I goof up!
I wonder if a pulse jet could be split into 6 or more in a ring, firing sequentially, to reduce vibration.
The timing of firing seems random, so I don't know how!
@@worldofwarbirds A car distributor from a 6 cylinder car, driven by an electric motor.
Once the pulsejet was running, the sparkplug no longer did anything. It was self-sustaining and self-timing from what I saw.
@@worldofwarbirds But it would be easy to replace the reed valves with a rotating disc, that has a hole that uncovers each tube in turn. If the pulse from each pulse jet overlapped with the previous, and subsequent pulses, the vibration and noise would be significantly lower, compounded with the affect of having 6 small pulses, instead of one really big pulse, it would be a more more practical solution.
Really really interesting. Thank you very much. But as interesting as the aircraft itself is, it also got me thinking: did anyone during The Second World War ever consider towing standard fighters behind bombers during raids? After all, one of the Luftwaffe's big problems during The Battle of Britain was the range of it's escort fighters. Would there have been some way to attach a Bf. 109 to the back of a bomber, have it take of under it's own power, then once cruising altitude had been reached, switch off the engine and glide the rest of the way until the combat area was reached? I wonder if this was ever considered.
Hi- apparently that was one of the ideas for the 328 parasite fighter.
@@worldofwarbirds Yes I recall from your video. That's what got me thinking about applying that concept to more conventional aircraft.
Not sure about the war, but the US played with the idea a few years after with an aircraft dubbed the "Goblin" that was supposed to be carried by bombers and dropped to provide air defense, before being picked up again for the flight home. The project was canned because the aircraft wasn't very good at being a fighter, and successfully reattaching itself to the mothership proved difficult and dangerous.
@@crudboy12 Before the war the US played with using airships as carriers
If the Luftwaffe had asked the Japanese they may have got some Zero's. Zero's could easily defeat the Spitfire (as proven in the battles over Northern Australia) and had around 8 hours endurance.
Was the V-1 an aircraft or a weapon? You asked the question. I'll take a stab at it, based on a little knowledge and lots more ignorance. (grin)
It all depends on whether you consider a Tomahawk cruise missile an aircraft or not. The V-1 was on of the first successful cruise missiles. It wasn't especially accurate, but it was accurate enought to hit a city at range, which was good enough for the Germans' purposes. I don't consider it to be any more of an aircraft than any other long range self-guided missile.
But then, I'm just a grumpy old fart. Love your channel. Keep it up.
I have a model kit of this aircraft.
Have you built it or is it waiting in the stash?
@worldofwarbirds It's among the waiting, sadly.
Pulse jets really can’t handle any g-forces, fuel flow gets interrupted by even moderate g-forces, and any fuel interruption means engine cut off. So, a totally useless idea.
When someone on the ground can hear you coming from miles away thats bad. When someone in another aircraft can hear you approaching thats epic.
the Fiesler Storch - ch does not sound like sh in English. It sounds like and almost K without the tongue totally blocking air
Still, not as bad as the SS rocket plane, Natter.
Yes, that one was crazy! I'll have to profile it someday.
Your explanation of a pulsejet engine is way off, and inaccurate. you are describing two types of engines as one type. Your first diagram shows a VALVELESS pulse jet engine (2:18) then you switch to a PULSE Jet engine.
Yes. I have added a correction to the video and a disclaimer to the description. Thanks for pointing this out.
Images of a shutterless pulse jet in this video should be deleted. Not relevant to the Me 328 program.
Thanks for pointing that out. I published an errata on the description and on the screen at the image. RUclips does not allow editing after publishing.
I cant help thinking What junk! But I bet using todays tech for perfect ignition synch? it could work vastly better? Lots of old designs can work much better with todays tech,,,,like old racing vehicles getting modern tires brakes and suspension for example could run circles around stuff of their day
That's a good question!

The AI images really don't contribute anything to this video. I wish creators would stop using them like this. You could use all of your other images like one second longer each and you'd more than make up the time.
Point taken.
I do not look american WWII videos - the half is a total lie.
This one is Canadian 🇨🇦! I try to be neutral, so I would prefer if you’d give me a chance and let me know how I did.
ai images too distracting (uncanny valley stuff), i had to stop watching.
There were only two images in the whole video!
@@worldofwarbirds as i said i had to stop. that bothered me because i really wanted to learn about a plane i knew very little about. but when you know some of whats presented is fake how can you trust the rest?
Get a life, 'I don't like it so nobody else can watch it' you're main player syndrome is showing. Now fk off
Stop whining, the world does not revolve around your silly complaints, grow up!
You can trust because I clearly label any instance of its use. Also, I haven't been able to use it for the actual aircraft yet, as AI so far can't tell the difference between a Me109 and a Lanc. But its quite good at: " black-and-white image of 1930s German technicians brainstorming futuristic aircraft ideas on a blackboard"
Concept that = bull shit 😂
Its stupid!!!
