Germany goes for centrifugal flow turbojet engines? (1 Viewer)

Well, both the USA and Germany had the same kind of government interference. Heinkel wanted to build a jet fighter complete with engines but the Nazi govt told them they were NOT an engine company, so they could not. Lockheed wanted to build a jet fighter complete with engines and the US Govt told them they already had a full plate, so no. Heinkel ended up buying the Hirth company, just so they could say they were an engine company. And of course Whittle struggled under the control of an automobile company and things did not really pick up there until RR traded their Meteor engine factory for Powerjets.

This stifled innovation, all over the place. Today SpaceX builds not only their boosters but the engines; at one time that would have been unacceptable to the US Govt.

Quoting from the book about the Pegasus jet engine, A.A. Griffith poo-pooed Whittles ideas in the 1930s. Guess hat that was not helping either :\

HeS30 does indeed look very impressive on paper. But hard to say they wouldn't have ran into similar issues that subsequently seriously delayed the 003 and 004?

Further, lack of exotic materials might imply a seriously limited lifespan for the hot parts? Unless they had invented something like film cooling?

In any case, considering how promising it was, canceling it was arguably a big mistake.

The HeS30 addressed and improved on the HeS8's issues and was performing reliably by Fall of 1942.
It's development had been delayed several times due to typical infighting, which seemed to be a typical condition within the German aircraft industry, existing at both the design level and with the RLM itself.

The HeS30's design incorporated less exotic materials than the Axials as well as being simpler in construction.

It was also capable of longer operation between refit as well as being capable of rapid RPM changes without a violent reaction, which plagued the 003 and 004 engines.

And again, it operated on Kerosene, which was yet another plus in it's favor.

What about Junkers?

And now a quiz! The winner is the one who finds the centrifugal compressor in the HeS 30.

A special prize to the person who can point out what exactly HeS 8 and HeS 30 have in common - apart from the company abbreviation and the general principle of getting thrust.
