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

Способ, заключающийся в отклонении вектора результирующей аэродинамической силы от направления оси вращения винта, характеризуется тем, что в процессе движения лопастей винта по азимуту окружности задают различные углы установки этих лопастей. Устройство для осуществления этого способа содержит винт с одной или более лопастью и механизм изменения угла установки лопасти, выполненный в виде цилиндра, охватывающего вал винта, на котором установлены концентричные втулки, взаимодействующие при помощи приводов с цилиндром с одной стороны и посредством ролика и механизма возврата, соединенного с лопастью, - с другой стороны. Торцы втулок, контактирующие с роликом, имеют ступенчатую форму. Цилиндр имеет индивидуальный привод и содержит упоры. 2 с.п. ф-лы, 8 ил.The method, which consists in deviating the vector of the resulting aerodynamic force from the direction of the axis of rotation of the screw, is characterized in that during the movement of the rotor blades along the azimuth of the circle, different angles of installation of these blades are set. A device for implementing this method comprises a screw with one or more blades and a mechanism for changing the angle of installation of the blade, made in the form of a cylinder, covering the shaft of the screw, on which concentric bushings are mounted, interacting by means of drives with a cylinder on one side and by means of a roller and a return mechanism, connected to the blade, on the other hand. The ends of the bushings in contact with the roller are stepped in shape. The cylinder has an individual drive and contains stops. 2 s.p. f-ly, 8 ill.
