FIELD: aviation.
SUBSTANCE: invention relates to the field of aviation, in particular to the constructions of autogyros. The device for rotor prespinning of unmanned autogyro comprises a drive shaft and pulley with a coiled cord, a free end of which is designed to be mounted on the launcher. Pulley by means of the threaded connection is screwed on the lower end of the drive shaft passed through a spherical bearing. The upper end of the drive shaft is connected to a two-stage joint transmitting the rotation to the shaft of the rotor of autogyro. Between the body of the autogyro and the pulley the slip-clutch is installed on the drive shaft.
EFFECT: with the help of the invention the decrease of flight weight and of aerodynamic drag is achieved.
