Fronn Wiki again.
The engine was extremely simple, made largely of sheet metal. Construction started late in the summer of 1936 and was completed in March 1937. Two weeks later the engine was running on hydrogen, but the high temperature exhaust led to considerable "burning" of the metal. The tests were otherwise successful, and in September the combustors were replaced and the engine was run on gasoline for the first time. Ohain had at last, albeit five months after
Frank Whittle, working in parallel in England, run a self-contained turbojet.
There was also an Italian turbine aircraft that usea a piston engine to drive the compressor.
