First off Gerhard Neumann Had absolutely nothing to do with German turbine engine development in WW2. The rest of your post is non-sense.

Duske,
You're making some pretty bold claims and yet you consistently refuse to provide any evidence to back them up. Where is the evidence that Rolls Royce copied any German jet engine technology to enable testing of an axial flow jet engine before the end of WW2?
The title of this thread is "first real jet engine" and yet you are focused solely on German axial-flow engines which, although operational, were hardly robust nor were they significantly advanced, technically, from other developments elsewhere.
Please start backing up your claims with something other than your own opinion.
Many thanks,
The Rest of Us

I think you are missing the point.
An axial flow engine is not automatically better just because it uses axial flow than straight through
Literally tens of thousands of engines using two stage centrifugal compressors have been built after the designers had seen the axial flow straight though engines.

QUOTE="Duske, post: 1375443, member: 73718"] Then a simple guard told me: The German
axial engine was the better one. So you better come down from your high nosed opinion.
The guard did know why - because he is confronted day by day with the same Problem.[/QUOTE]

Sorry to tell. The GE J 79 was the base - since today. At least during the last 50 years this one was the basic one.
At the end of all crashed F 104 GE stated the mistake. During air combat at low Level for escaping the Pilot activated the afterburner.
After less of one Minute he did shut off the afterburner. This did lead to a flame out - as the engine was not at full power - no Chance ever. As you may know at high altitude you have only one Chance left to restart a engine. I am a Pilot since 60 years.

You are completly right ! England missed the Chance to create an axial Jet engine. Germany was forced to do so.
The Germany of does days was a misled Nation and a Herr Hitler was an Idiot. But we have shown better by now.

Sorry to tell, but the B-52 used the Pratt & Whitney J57, not the GE J79 which was used in B-58 and F-104 just to name a few. Neither one of those engines traces its lineage to the German issue of WWII.
I'm still confused that you stated that there were no British engines "in the game". The hell does that even mean?

The GE J 79 I catched from Wikipedia. But you are right it was the GE J 57 - constructed by the German Neumann as I said, the director of
General Electric of does days. Well known in the States as Herrmann the German. He became director of GE because the J 57 he designed became so famous. Some air-museum museum in Germany are named after him. So the J 57 traced ist lineage to the German axial Jet engine as Neumann was one of the heads of BRAMO. Just ask Hanns to learn more about
England does not exist in the discussion it is the UK. It didn't "miss a chance" it was developing engines of both axial and centrifugal types.

Where is your problem - by just naming facts[/QUOTE]
How about you answer the question that's been asked at least 3 times now...what evidence do you have that Rolls Royce copied German jet technology during WW2? If the UK wasn't aware of axial technology, as you're claiming, surely it would take more than a few months for RR to reverse engineer the German engine AND then enhance it to provide better thrust. So where's your evidence of such events?

Uh... Gerhard Neumann did work at General Electric and helped design the J79, again, the J57 in the B-52 was a Pratt & Whitney design. Also, you do know that Gerhard Neumann never worked on German jet engines during the war right? He was in China when the war started and ended up working for the U.S.A.A.F.
He was in China solely because he did not want to be in Germany. I wonder if Gerhard liked being called "Herman the German".

Website with list of German F104 crashes.
916 Starfighter
after reading over 40 of them less than 25% are engine related at all, let alone afterburner related.

Gerhard Neumann was a German, born in Germany. He worked with BRAMO till 1939 by receiving the knowlegde of constructing jet engines. At that time BRAMO did produce the radial one of von Oheim. In october 1938 Messerschmitt received order building a Jet. Messerschmidt had worked on that project long before - it received the order number P 1065. He then contacted BRAMO for a slim Jet engine.
Neumann was a part of it.
Thats why he was able constructing within a short time the J 57. He did not help constructing the J 57 - he was the leader of the J 57 programm. Due to the great success he reached with the J 57 he became the director of General Electric. His last visit to Germany he made in 1997 by being invited opening up 2 air.museum under his name. In China he worked for the US on radial egines only.
Everyone in US-Aviation knows about Hermann the German regardless whether you like it or not. I did live in the States for six years.
Why did you people send the week Whittle one to the US when having a good running axial Jet engine in spare ? NONSENSE !

Odd that his biography doesn't mention P&W....
The newlyweds drove across Asia in a Jeep that Neumann had cobbled together from two wrecked vehicles. Still restless, they departed on a 10,000-mile journey to the Holy Land and the Middle East.
Neumann mailed an application to G.E.. What followed has become aviation industry legend. Neumann devised ways to make GE aircraft engines stronger and more efficient. He subscribed to the "dirty fingernails" school in which all engineers must physically delve into their engines. Jets were his passion and he spent hours studying how air passed through an engine's fan blades. His management style was frequently described as precise and uncompromising, and he was known to berate employees he deemed incompetent while frustrating his superiors with his freewheeling antics.
