Flexible connection rotor cabin helicopter

Abstract

A flexible connection rotor cabin helicopter is characterized in that a rigid beam is connected with a helicopter body cabin, a flexible component of a rotor cabin and a flexible component of a tail rotor cabin; the flexible connection rotor cabin helicopter comprises a helicopter body cabin, a plurality of rotor cabins, a rigid beam and a flexible component, or a rigid beam is connected with the flexible component of the helicopter body cabin and the flexible component of the plurality of rotor cabins, wherein the left rotor wing and the right rotor wing are identical in size and opposite in rotating direction, and a vertical tail is arranged at the tail of the flexible connection rotor cabin helicopter, or the rigid beam is connected with the flexible component of the helicopter body cabin and the plurality of rotor cabins. The two rotors with the same size and opposite rotating directions are arranged in the transverse direction, the two rotors with the same size and opposite rotating directions are arranged in the longitudinal direction, transmission shafts are not arranged between the rotors for linkage, and the weight of a transmission device is reduced; due to the arrangement of the flexible components, mutual transmission of harmonic vibration generated by flapping of the blades of the rotors is blocked, resonance is prevented, and the unmanned aerial vehicle has the advantages of being large in load capacity, simple in structure and flexible to operate and is suitable for the fields of transportation, agricultural operation, aerial photography and the like.

Description

Technical field[0001]The present invention relates to a flexible connecting spin wrap helicopter that does not rely on vertically and rises from the airport, hover, and around left and right.Background technique[0002]It is currently known to achieve a helicopter, a helicopter, a helicopter, a helicopter, a helicopter, and a single-spin-helicol helicopter, and a single rotor helicopter has a simple manipulation of a simple manipulator, but a single rotor helicopter. The torque is completely tail propeller perpendicular to the rotating surface, the propeller does not produce the lift of the vertical direction, the power consumption, the linear double-rotor helicopter, due to the same pair of positive and negative rotation of the same as the equation, the anti-torque of the rotor Cancel, saving the power consumption of the tail propeller, but the two dimensions are the same, and the opposite rotor must participate in pitch, roll, and the manipulation of the direction, the manipulation ...

AI Technical Summary

Problems solved by technology

[0002] At present, the known successful methods of helicopters that can realize vertical lift, hovering, front, rear, left, and right flight include single-rotor helicopters and tandem dual-rotor helicopters. The torque is completely balanced by the tail propeller which is vertical to the rotating surface. This propeller does not generate lift in the vertical direction and consumes power. The tandem dual-rotor helicopter adopts a pair of forward and reverse rotors with the same size at constant speed, and the counter torque of the rotors interacts with each other. Offset, the power consumption of the tail propeller is saved, but two rotors with the same size and opposite directions must participate in the control of pitch, roll and heading, and the operation is complicated. A pair of forward and reverse rotors needs to be reversed synchronously, and the transmission power Large, complex transmission components, heavy weight, and difficult shock absorption
