3-wing rotor of model helicopter using elastic force of rubber band

摘要

The present invention relates to a structure of a model helicopter, in which a real helicopter drives a rotor located at a tail portion of a fuselage to prevent the fuselage from rotating due to rotation of the rotor due to rotation of the rotor located at the upper end of the fuselage, A 3-wing rotor of the same size as a 3-wing rotor located at the upper end of the fuselage at the lower part of the fuselage without the rotor of the tail part is mounted so that the direction of the wing of the rotor is opposite and the center of the two rotors is connected by a single rubber band. The generated restoring force acts on each of the rotors located at the upper and lower ends in the same direction and rotates in the directions opposite to each other, thereby canceling the rotational forces of the rotors on the helicopter's fuselage to cancel each other so that the fuselage of the helicopter does not rotate, To increase the number of
