The Flettner Fl 265 was an experimental helicopter designed by Anton Flettner.
Design and development
This helicopter, developed in 1938 with the support of
synchropter, had two intermeshing rotors 12 m in diameter, powered by a 160 hp (119 kW) BMW-Bramo Sh 14 A radial engine in the nose of the fuselage, fitted with a fan to assist cooling. Six helicopters were constructed, but series production was curtailed in favour of the Flettner Fl 282.[1]
In 1939 the helicopter was tested by test pilot Richard Perlia. A second test pilot alongside Perlia unfortunately had a fatal accident during a test flight.[2]
