Problems solved by technology

The disadvantage is that in order to obtain a large lift, the size and weight of the rotor increase, the shimmy Coriolis force generated by the blade waving increases, the vibration increases, and the centrifugal force increases, which increases the difficulty of manufacturing the hub and rotor.

Abstract

The invention discloses a parallel helicopter which is characterized in that a first single-rotor helicopter is connected with a second single-rotor helicopter through a connecting cross beam on the basis of the first single-rotor helicopter, and the longitudinal axis of the connecting cross beam is overlapped with or parallel to the projection of a connecting line of rotating centers of rotors of the first single-rotor helicopter and the second single-rotor helicopter on a horizontal plane; a warehouse fuselage is arranged near the midpoint of the connecting cross beam, the rotating directions of rotors of the first single-rotor helicopter and rotors of the second single-rotor helicopter are the same, in order to further increase lift force, a propeller is arranged at the top of the warehouse fuselage, and the rotating direction of the propeller is opposite to the rotating directions of the two rotors of the parallel helicopters; the control load of a tail propeller is reduced, more propellers are additionally arranged on the two sides of the warehouse fuselage to achieve re-increase of lift force, the engine driving rotors, the warehouse fuselage top propeller, the warehouse fuselage two-side propellers and the tail propeller are driven by the engine driving the rotors through transmission shafts, and the transverse arrangement is suitable for wide agricultural operation occasions.

Description

Technical field[0001]The present invention relates to a parallel helicopter that does not rely on vertical hemps, hover, and left and right, and left and right.Background technique[0002]It is currently known to achieve a vertically illegal, hover, and a single-round helicopter, which has a single rotor helicopter, which waits the device on the paddle on the hub, eliminating the front roller lobe to increase, and the row of paddle is reduced. The lift does not symmetrically, it changes the torrential angle of the rotating blade paddle controller, changing the rotary force of the rotating force, and changes the pitch and roll of the helicopter, and the tail propeller peripheral rotating surface is removed. The torque of the rotor and manipulates the flight. The disadvantage is to obtain large lift, the size, weight of the rotor increase, the rumor wave is increasing, the vibration is increased, the vibration is increased, the centrifugal force is increased, and the hardware manufactur...
