Based on Frank Whittle's patent, as von Ohain admitted. He got his engine to run before Whittle did, thanks to massive funding from Heinkel, but it was a failure. Whittle's engine was developed on minimal funding, and made it to combat during WW2 in the Gloster Meteor
@@scootergeorge9576 Had politics not got in the way, the British jet program would have come to fruition 1 1/2 to 2 years earlier. It was a proper development program, with supporting development of materials such as high-temperature alloys. The engines were safe and durable, before they entered service. The Ohain / Heinkel engine was a failure, because the design was poor, and like all the other German jet projects, they lacked supporting technologies such as high-temperature alloys. None of the German jet engines had a life-cycle beyond 12 hours, and they were unsafe in use - prone to flame-outs, and could not be throttled up or down rapidly. Quite simply, all the German jet programs were rush projects, and far from combat-ready when they were put into production and active service. They needed a lot of expert servicing, and an expert to fly them - neither in good supply at the end of WW2.
@@paulstandeven8572 - You are mostly correct, Paul. The RAF could have had jet aircraft much sooner had Whittle received the funding his ideas deserved. There were a couple of issues with the German jet engines. One, as you stated was rapid throttle movements were not possible. But based upon my experience with jet engines in the USN, this was because of the crude fuel controls early jet engines used. By the fifties, if not sooner, jet engines used automatic fuel controls that allowed for maximum engine acceleration without overtemp and or compressor stall. As a backup, in case the complicated, mechanical mechanism failed, was an emergency, "manual" setting. When tested on the ground, I was a mechanic, throttle movements had to be slow and gradual. What the Germans did, as in the 004, was install a pilot controllable variable exhaust nozzle to vary thrust and turbine inlet temp independent of throttle position. The lack of airframe speed brakes also hindered Me 262 ops. Another problem German engineers faced was a shortage of high temp resistant metal alloys such as nickel. To work around this, the Jumo 004 used hallow, air cooled turbine vanes. By the end of the war, engine life improved from 10 hours to about 50 or more.
@@paulstandeven8572 he HeS 8 was only very loosely "based" on Whittle's design, and it's development did not receive "massive" funding. The V16 variant of the HeS 8 was running fairly reliably by the autumn of 1942. The fact that it was not ordered into mass production does not make it a failure.
Equilibrage dynamique d'une turbine (joli banc!), alors qu'une virole est déjà installée en sandwich. C'est délicat mais faisable. L'aéronautique se permet souvent des solutions que la grande série refuserait pour leurs couts et risques. Dynamic balancing of a turbine (nice bench!), while a ring-assembly is already sandwiched into. Delicate but feasible. Aeronautics often allows solutions that the big series would refuse for their costs and risks.
This is Hans von Ohain's attempt to make a jet engine. As he admitted, he closely looked at Frank Whittle's patents on the principle of the jet engine, before beginning his own design - uniquely with centrifugal compressor and turbine.. He got lots of funding from Heinkel. His engine ran before Whittle's did - but it gave little power, and was very inefficient. It failed - but it is interesting to see this video
Nah. Never happened. Whittle copied Maxime Guillaume's 1921 jet engine patent. Ohain's engine was centrifugal flow, which is an inferior but simple design. The German's dropped the centrifugal flow engine and Anselm Franz invented the vastly superior axial-flow engine used in the 262. Meanwhile, the British were stuck with centrifugal flow engines. The British failure to develop an axial-flow engine is directly linked to the failure of the Meteor, which was never used in WWII combat. Hope this clears things up for you!

Как рабочая модель - такой двигатель интересен. Но в целом, особенно для сверхзвуковых скоростей - тупиковый. Слишком большое внутреннее сопротивление из-за многих поворотов потока, а для сверхзвука - центробежный компрессор, как стена. Хотя в целом это была революция - тепловой двигатель непрерывного цикла и такой вариант двигателя надо было пройти для понимания дальнейшего развития. Ведь всё же он полетел. Да и нынешние модельные в основном подобной компоновки. As a working model - this engine is interesting. But in General, especially for supersonic speeds - a dead end. Too much internal resistance due to many turns of the flow, but for supersonic centrifugal compressor as the wall. Although in General it was a revolution - heat engine cycle and this version of the engine had to go through for further development. After all, he flew. And the current model is basically the similar layout.

Werden da am Anfang der Kompressor und die Turbine gewuchtet ?
Michael Meineker ja
Excellent moi!!👏🌠🛩️💫🌐
Give a German a tin can and he will make a cannon no other nation possess this inguenity execpt of course the Japanese who are not too far behind.
Or the americans who just copied......
Germans just copied British jet engines.

We had TV at first, we had jets at first, we had rockets reaching space at first, we had the first car, but the British had steam-engines at first.
