Synchronous switching adjusting device of coaxial double-oared self-spinning wing aircraft

Abstract

The invention discloses a synchronous steering adjuster of coaxial dual-screw self-spin aircraft, which is formed by power driving device, power transmission device, and adjust controller, wherein the power transmission device comprise an inner axial universal joint formed by spherical universal joint and annular universal joint, and inner and outer axles connected to the upper and lower rotors; the adjust controller comprises an adjust control handle, a taper steering tooth, reducing damper, and the inner and outer axial tooth discs that rigidly connected to the inner and outer axles and meshed with steering tooth; since the rotation speeds of upper and lower wings are controlled by the reducing damper, and the invention uses aforementioned synchronous steering operation as coaxial, sheathed inner axial universal joint and straight meshing, the inventive device has simple structure, small volume, and high transmission efficiency. With said invention, the aircraft can vertically fly to any height for long time, without direction deflection.

Description

technical field [0001] The invention relates to a flight control device, in particular to a synchronous reversing control device suitable for a coaxial dual-blade self-rotor aircraft. Background technique [0002] Popular aircraft in the world today mainly contains the fixed-wing aircraft that needs to have the special-purpose runway of considerable length to cooperate when taking off and landing and the rotary-wing helicopter that does not need to fix the special-purpose take-off and landing ground to cooperate two big classes. The characteristics of fixed-wing aircraft are that the fuselage is relatively large, the flight is relatively stable, safe, quiet, and fast, and the number of passengers is as few as one or as many as several hundred. Rotor helicopters are characterized by relatively small fuselage, high flexibility and maneuverability, can take off and land in various places, and can also perform various special flights such as vertical flight in the air, hovering,...

AI Technical Summary

Problems solved by technology

Rotor helicopters are characterized by relatively small fuselage, high flexibility and maneuverability, can take off and land in various places, and can also perform various special flights such as vertical flight in the air, hovering, side flight, inverted flight, circling flight, etc. , its shortcomings are that the structure is very complex, the operation is difficult, the maintenance work is heavy, and the cost of use is high. In addition, due to structural limitations, this aircraft has no emergency escape facilities and gliding functions, so in case of mechanical accidents during the flight In the event of a breakdown, it is difficult for the crew to survive

But so far, the power transmission control mechanisms developed by countries all over the world have very complex structures, large volumes, low transmission efficiency, complex manufacturing processes, and great difficulty in processing and assembling, so the production costs are very high.
