sempre senz' offesa - guarda anche questo, quant'éra avanti ai suoi tempi, il 1° thermojet, un misto de turbina e motore alternato, e funzionava -- nel 1910 :

Coanda-1910

solo che "il mondo" ci capiva un...tubo

Funzionare... parola grossa...

"Decades later, after the practical demonstration of motorjets and turbojets, Coandă asserted that his turbo-propulseur was the first motorjet engine complete with fuel combustion in the air stream.
He also said that he had made a single brief flight in December 1910, crashing just after take-off, the aircraft destroyed by fire. Two aviation historians countered Coandă's version of events, saying there was no proof that the engine had combustion in the air stream, and no proof that the aircraft ever flew."
