Somebody please tell me the aircraft of which nation were routinely capable of speeds in the region of 550 mph in level flight by war's end?
But, once again, I will ask what Allied aircraft had equivalent performance to the Me262 as of VE Day?
Although the above is really just a red herring being repeated, as it doesn't address jet engine technology specifically, instead changing the subject to jet aircraft, the answer is:
The US P-80, Britain's Vampire and Meteor, Bell's XP-83. All were flying before VE Day.
All you counter with is "so what", "irrelevant" etc.
No sources to counter the ones that I refer to.
Your posts have the value equivalent to a six year old throwing a tantrum.
They are not worthy of my time and effort conducting pertinent research.
Another fallacy diversion, this time an appeal to authority rather than responding to what was presented coupled with ad hominin. I answered the questions you asked, but apparently you don't like the answers.
The problem wasn't so simple as just metallurgy. There were issues with uneven heating, lubricants, and a plethora of other issues that had to be worked out. Superior metallurgy helped, but it wasn't the be-all, end-all of the issue.
For example, Vickers on their F2 Freda (later variants were named Beryl) engine (roughly analogous to an improved Jumo 004) first flew in June 1943 on a Avro Lancaster as a test bed. This same engine was fitted to a Meteor and flown in November 1943. The Freda produced about 2,000 lbs thrust versus 1,600 for the Whittle engine.
The reason it wasn't early adopted was the engine was considered unreliable and Vickers continued to work to improve that. But the point stands. The British had jet engine technology equal to or superior to that of Germany, just as the US did in 1945.
Were there any Metropolitan Vickers turbojet engines in production as of VE Day?
The F2 Beryl was production ready but the British choose not to introduce since they were winning the war
and thought they could do much better with further development. That was the correct decision on their part.
In May 1945 the Germans realistically had two engines in production, the BMW 003 and the Jumo 004. They had one in a state of development similar to the US GE J35 and British Vickers F series, the Henkel 011. The Henkel was really a throwback however, being a compound compressor engine with a centrifugal stage followed by a three-stage axial compressor.
Postwar, it became clear that centrifugal turbojets were not the future and their development was curtailed in favor of axial designs.
The Germans, in wartime, pressed by the situation and nearing defeat rushed their jet engines into production and service accepting the limitations of short engine life and poor reliability because of that. The Allies, with equally advanced technology weren't so pressed as they were winning and they knew it. They had the luxury of taking more time to develop reliable systems, but that doesn't mean they were behind in technology, they weren't.
