Big wide smile watching this. ❤

[@rexididia6624]

Beautiful

[@alejandroneri8782]

Amazing video

[@longlivelouis]

They would make cute car rims , in another world they would also make cool car tire engines ,like riding on air lol

[@longlivelouis]

Some mix of air , hydro, steam ect power , the more the merrier right lol

[@tar244you8]

what about the ultra fan ?

[@Dakshgamerig]

Give me

[@PhillipMorton]

Can you hold the camera still please? Motion sickness here

Watching while walking is much better.

U sound Weak

[@danielbigtiger]

If Trent engines have a serrated blades.

Everything has a margin of error except Rolls Royce engines.

Looks like they learnt from qf32.

Kachre wala Rolls-Royce 1920 ke

[@YT_Lofi_Studio]

Mere paas itni power hai ki Rolls Royce mere pass notification bhejta hai😂😮🎉❤😊

[@HughNeylan]

Great video. Do you employ any women?

[@Fc_Verstappenz]

First

[@gazza2933]

No you're not. Rolls Royce are 1st. 👍

[@anonymously241]

How much this big electric fan cost? 🤦‍♂️🤦‍♂️

[@mazelme]

My kitty just farted a tiny, little cat-fart.

Germany invented jet engines (or at least flew them first)

[@grahamj9101]

No! Germany did not! Frank Whittle's UK patent of 1930/31 predated that of Hans von Ohain by several years. Whittle's patent was published and distributed to both industry and technical institutions in Germany by the Patent Office in Berlin in 1931, and it is quite possible, therefore, that von Ohain may have seen it. In any case, a Belgian by the name of Maxime Guillaume was granted a French patent for a crude form of axial flow jet engine in 1921. Heinkel's He178 first flew for six minutes with von Ohain's engine in August 1939. It was certainly the first true jet aircraft to fly, but the engine could only be run for a few minutes at a time: it certainly wasn't airworthy by British standards. Frank Whittle's W.1 engine, in the Gloster E.28/39, did not fly until May 1941: however it was airworthy and, after an uneventful first flight of seventeen minutes, the aircraft was put into its hangar with no attention given to the engine. The W.1 was very conservatively cleared for 10 hours of flight, which it comfortably achieved and, on inspection, the one small defect observed was a small crack in a combustion chamber. Having been replaced with the improved W.1A, engine, the W.1 went on to do many more hours of ground running, before suffering a turbine failure. The engine is still to be seen in the Science Museum in London. You may be interested to know that, in 1944, the Jumo 004B in the Me262 had efficiency, performance and fuel consumption figures that were inferior to those of the W.1 in 1941. The handling of the 004B was also abysmal: any rapid movement of the throttle could induce a surge and flameout. At the end of the war, the British centrifugal engines were significantly superior, in terms of both performance and reliability, to any axial flow engines in existence at the time. It took until the end of the 1940s for axial flow engines to supplant centrifugal engines. Even then the Klimov VK-1, a reverse-engineered Rolls-Royce Nene, which powered the MiG-15, was competitive with the axial flow GE J-47, which powered the F-86 Sabre. The VK-1 was marginally less efficient, with slightly less thrust, but was significantly lighter than the J-47. The Sabre was a better fighter plane than the MiG because it was superior aerodynamically, not because it had a better engine.
