FIELD: rotary-wing flying vehicles, autogyroes in particular.
SUBSTANCE: proposed head has rotor hub unit connected with swivel joint of hub and aerodynamic surface connected with hub axle. This surface is so positioned that rated point of application of resultant aerodynamic force is shifted towards tail section of autogyro from axis of longitudinal swinging of hub. Aerodynamic surface is mounted on member rigidly connected with hub axle. Aerodynamic surface may be provided with device for change of its angle, may be located on either side from longitudinal plane of symmetry and may be symmetrical relative to this plane of symmetry.
EFFECT: enhanced aerodynamic stability of autogyro in flight; reduced level of vibrations of rotor head.
