Sud-Est SE-3101

The purpose of this experimental single-seater was to study the placing of auxiliary rotors intended simultaneously to provide torque correction and longitudinal control. Two rotors, with compressed wood blades 1.6m in diameter, were placed symmetrically at 45°, one on each side of a V-shaped beam at the end of the fuselage, which was made of soldered tubes without a skin covering. These variable-pitch airscrews enabled the aircraft to be steered by varying their pitch differentially.

This helicopter flew for the first time on 1st June 1948.
