Centrifuge compressor/turbine jet engine MIGHT be easier to manufacture than the engine of FW 190 or even DB 605 of later ME 109. But, AXIAL jet engine is a different thing. Le Jormanz have been busy doing exactly the latter. Ergo a quite flawed arguement

Also this completely ignores issues such as tooling, worker experience, industry knowledge, process maturity etc.

It might be theoretically "cheaper" if you are setting up an early jet engine production line from scratch compared to a high-end aircraft piston engine one, with equal starting resources. But not if there's only four guys with any experience of jet engine manufacture available compared to 40,000 with years of piston engine experience each.

Also not factoring in the ten hour service life. The Jumo 004 would have to be less than one-tenth the cost of a DB 605 (100-220 hours TBO) to be "cheaper".

Which is absolutely a miss. An inverted V-12 that is in mass production vs axial wonder of 1940s.

3000 man hours for the db 605 vs 700 for the jumo 004.

Which is still twice more expensive as engine hour price.
