Very interesting design and far ahead of similar ''inventions''.
Mr. de Chappedelaine also worked on a helicopter in the USA and what strikes me was the strong similarity in the fuselage lines. Reportedly this helicopter was built around 1946-1947 by or on behalf on American Die & Tool Company. It was a so called cold jet type with hollow rotor blades and engine driven compressor.
I never found out whether it was actually completed and/or flown and miss info on engine, dimensions etc.
