Djinn completed at Toulouse

A team of volunteers from Ailes Anciennes Toulouse, led by former French Army helicopter mechanic Claude Trainier, has recently completed the restoration of an SO1221 Djinn. This minuscule French helicopter relied on compressed air, ejected from blade-tip nozzles, to drive its main rotor. Using this concept, no mechanical link between the rotor and the engine existed, eliminating torque and thereby the need for a tail rotor. Directional stability was maintained by a rudder placed directly behind the turbine. Powered by
