A tilt-rotor aircraft and its driving method

Abstract

The invention discloses a tilt-rotor aircraft and a driving method thereof, belonging to the technical field of small aircraft. The tilt-rotor aircraft includes three rotor shafts, five rotors, a motor and a mixer. The three rotor shafts are arranged in an inverted triangle and can rotate around the plane of the fuselage; a lift rotor is installed on the tail rotor shaft; it is located in the front A pair of coaxial tilting rotors are respectively installed on the two rotor shafts, that is, the upper and lower rotors are installed on the same rotor shaft, and the upper and lower rotors rotate in opposite directions and rotate at the same speed; and the two pairs of tilting Among the rotors, the two rotors on the same layer rotate in opposite directions, and the two rotors on different layers rotate in the same direction. In the present invention, the aircraft can still work stably under the conditions of dynamic performance changes; the present invention adopts a coaxial structure, which is still controllable as long as the two tilt rotors on one side do not fail at the same time; the volume of the aircraft and the key power are reduced. For the unit impact area, only two sets of tilting mechanisms are required.

Description

technical field [0001] The invention belongs to the technical field of small aircraft, and in particular relates to a tilt-rotor aircraft and a driving method thereof. Background technique [0002] Tilt-rotor aircraft is a new type of aircraft that integrates fixed-wing aircraft and helicopters. It has both the vertical take-off and landing and aerial hovering capabilities of ordinary helicopters, and the high-speed cruise flight capability of fixed-wing aircraft. [0003] A tiltrotor is a rotorcraft with unique performance. It is similar to the two wingtips of a fixed-wing aircraft wing, each with a set of rotor tilting system components that can be rotated between a horizontal position and a vertical position. When the aircraft takes off and lands vertically, the rotor shaft is perpendicular to the ground, in a horizontal helicopter flight state, and can hover in the air, fly back and forth, and fly sideways. After the tiltrotor takes off and reaches a certain speed, the...

AI Technical Summary

Problems solved by technology

[0005] 1. During the transition from vertical take-off and landing mode to horizontal flight mode, the dynamic performance of the aircraft itself is changing, which has a certain impact on the stability of the aircraft itself, which makes this type of aircraft have certain hidden dangers in safety

[0006] 2. The existing tilt-rotor aircraft still has the problems of heavy weight and high power consumption, and there is room for further improvement

[0007] 3. The failure of one side of the traditional tilt-rotor aircraft has a serious impact on the stability of the aircraft, and there is a high probability that it will lose control, and the loss of transmission efficiency will increase after the compensation system is installed.
