Nice one!

Nice one!

He didn't invent it its historically incorrect and bolloks. He has no patents before 1939, the master patent was the Whittle one. If you look at the original Whittle drawings you can see where the Nazis got their ideas. At a Symposium von Ohain collared an RAF officer and told him the idea was Whittles. The only German jet engine patent before the war was one with Max Hahn and Ernst Heinkel. If you look at the performance and flight prfile of the Gloster E28/39 it was far superior to the early German jets. That jet only flew in a straight line for six minutes and that was it.
This myth was created by the Americans after WW2 for some obscure reason. People should check the facts before making assumptions.

Inventing the Jet engine does not necessarily mean he is attributed the invention (as probably most people generally think).
These are super rare interviews with Von Ohain, recently digitized at Pinewood Studios from 16mm film.
On the channel, we also have Whittle's complete interviews (one part is still missing). Also digitized from 16mm film.
If you watch both of them, you can easily make up your mind.
Personally, I absolutely think that not only is Whittle the true inventor of the turbojet, but he had a profound understanding of the temporal downside of his centrifugal solution. but at the same time, he also understood, at the end of the 20s, that the axial turbojet would require years and possibly decades to be developed into a viable turbojet, which is precisely what happened.
It looks like you commented without even watching the video, which is a pity, as you would have simply added precious details to what you already know.
I invite you to watch Von Ohain's complete interview (below), as well as Whittle's interviews (starting from part 1).
There is much to learn from them.
By the way A.A. Griffith, Whittle's nemesis, the very person that was most responsible for delaying Whittle by at least six years, was coincidentally the author of a seminal paper on axial compressors (1926). so you can easily see why he had every interest in dismissing Whittle, who thanks to him went largely ignored for too many years.
It was only thanks to a small private investment in mid-1935 that Whittle could push to build his turbojet. He achieved that in less than two years, in April 1937.
If Griffith, Whittle's sole judge, had green-flagged his project in 1929, and rather than a small investment, he had been supported by the Air Ministry, you can safely say that Whittle's engine would have been properly operational well before the beginning of the war.
We also know that the He 178 (Von Ohain) was mix powered, also incorporating Whittle's ideas, which had conveniently been copied and distributed across German universities, as Whittle did not have the money to renew his patent, and the British government had not protected with secrecy, still thanks to Griffith.
Despite being one of the fathers of the turbojet, Griffith made one of the most egregious mistakes of pre-WW2, most likely for a mere blatant conflict of interests, or simple jealousy, but you can hear all that from Whittle's own words.

I really urge you to watch them, as the stark difference between Whittle and Von Ohain is obvious, including the German engineer admitting he did not have the slightest clue about the true benefits of a turbojet, other than comfort and sound, a very limited understanding of the topic.
On the contrary, Whittle, in his thesis as a student (1920s), has a profound understanding of the topic, as well as of other key aviation factors, including the necessity of pressurization.

Great stuff!-but the best publication is the report by Stern for the 1920-21 Technical REPORT OF THE AERONAUTICAL RESEARCH COMMITTEE FOR THE YEAR 1920-21.
(With APPENDICES). In it is
The internal combustion turbine —By W. J Stern, B Sc ,
A R C Sc , D I C , of the Air Ministry Laboratory, South
Kensington Presented by the Director of Research ... Page 690, this paved the way for the turbine for aircraft use. As early as 1918 Beardmore were looking at a steam turbine for the Handley Page V1500. Unfortunately the boiler was the length of the fuselage. But simply put Whittle did it first.

Interesting!
By the way, according to Whittle, an inspiring book as a young student was: "Steam Turbines" by Dr. A. Stodola, published in 1905 by Archibald Constable and Company LTD. in London, and D. Van Nostrand Company in N.Y.
It also had an appendix on "Gas turbines and the future of heat engines."
Stodola, at the time, was a professor at the Polytechnic in Zurich, Switzerland.
He was a Slovak engineer.

Thanks for posting. This leads to the turbine work by Brown Bouverie, but the reality of it all is for aircraft Whittle did it first

I agree; ultimately, what matters is who invented a working turbojet.
There are other notable examples of people who theorized but never made one.
Considering that Whittle had to face all possible obstacles, ranging from Griffith's blatant dismissal of an excellent invention to complete lack of funding, which led Whittle to be unable to renew his patents, shamefully not even secreted by the British government, and therefore handing them on a silver platter to Germany, which duly copied his work and distributed it across German universities, crucially and conveniently landing on the desk of the pampered and fully funded Hans Von Ohain (he initially denied that fact, but later both him and his assistant both confirmed it).
The celebrated He 178 was mix-powered, which was perhaps not a coincidence.
Von Ohain's axial turbojet was as flawed as it could get at the time, like all other examples from Germany and Britain.
As correctly predicted by Whittle in late 1920, it would take decades to build a viable axial turbojet.

This is the fifth and last part of the interviews. Perhaps the most interesting:
