1938 Leduc Thermopropulse powered Stratospheric Aircraft

[Archibald]

"thermopropulser" in the title doesn't mean anything.
It should be
- "thermopropulsé" (passive)
- "thermopropulseur" (name, propulseur = engine)
- or "thermopropulsive (adjective, applied to "tuyère" "nozzle" = tuyère thermopropulsive".
