Abstract
FIELD: aeronautical engineering. SUBSTANCE: method consists in deviation of vector of resultant aerodynamic force from direction of axis of rotation of propeller; in course of motion of propeller blades in azimuth, circles set different blade angles in sections from 0 to π radians and from p to 2π radians. Device for realization of this method has propeller with one or more blades and mechanism for changing the blade angle made in form of cylinder embracing the shaft of propeller on which concentric bushes are mounted. These bushes are engageable by means of drives with cylinder on one side and by means of roller and return mechanism (which is connected with blade) on other side. Ends of bushes which are engageable with roller are stepped in shape. Cylinder is provided with individual drive and stops. EFFECT: enhanced reliability. 3 cl, 8 dwg
