The Focke Achgelis Fa 61 was the first fully controllable helicopter.
It first flew in 1936. It is more properly known as the Fa 61 as it was a research
aircraft of the Focke Achgelis company.
Prof. Heinrich Focke and engineer
Gerd Achgelis started the design for this helicopter in 1932. The airframe was
based on that of a well tried training aircraft, the Focke-Wulf Stieglitz. A single
engine drove twin rotors, set on outriggers to the left and right of the fuselage
the counter rotation of the two rotors solved the problem of torque reaction as
also shown by Louis Bréguet Only a prototype was produced. In February
1938 it was demonstrated by Hanna
indoors at the Deutschlandhalle sports stadium in Berlin, Germany.
It subsequently set several records for altitude, speed and flight duration
culminating, in June 1938, with an altitude record of 3,427 m and a straight line
flight record of 230 km.
