METHOD OF CONTROLLING THE RESULTANT AERODYNAMIC FORCE PRODUCED BY A PROPELLER AND A DEVICE FOR CARRYING OUT THE SAID METHOD

摘要

The present method consisting in deflecting the vector of the resultant aerodynamic force from the direction of the propeller axis, is characterized by that while the propeller blades move to a circle azimuth, the various angles of the blades are set on portions from O to pi radians and from pi to 2 pi radians. A device for carrying the method into effect comprises a propeller with one or more blades (4), and a blade angle control mechanism shaped as a cylinder (5) encompassing a propeller shaft (1) and carrying concentric bushings (8 and 9) adapted to interact on the one side with the cylinder (5) through drives (10 and 11), and on the other side, through a roller (12) and a return mechanism (13), with the blade (4). The ends of the bushings (8 and 9) contacting the roller (12) are stepped in shape. The cylinder (5) has its own drive (6) and comprises stops (7). <MATH>
