Anton Flettner, well known for his helicopters in Germany emigrated to the USA in 1947 and
founded the Flettner Aircraft Corporation. There he designed a heavy lift helicopter with
gas powered intermeshing rotors. Forward propulsion was given by two propellers, the rotors
should turn freely during forward flight and only be powered for take-off and landing, or low
speed flight. Rotor diameter was 23.5 m, length25.8m and payload about 3 tons. The compound
helicopter was desiganted Model 201.
(Information and drawing from vertiflite Summer 2003)

Another project shown in that article, but just as a sketch, was the model 200, proposed
to the USN. It was a one-man helicopter, with a two-bladed rotor powered by two pulse jets,
mounted on beams perpendicular to the rotor blades.
