Aircraft and aircraft control method

Abstract

The invention discloses an aircraft and a control method of the aircraft, the aircraft comprises a fuselage, a first rotor mechanism and a second rotor mechanism, the first rotor mechanism is connected to the fuselage through a first connecting mechanism, the second rotor mechanism is connected to the fuselage through a second connecting mechanism, and the first rotor mechanism and the second rotor mechanism are spaced and arranged diagonally. The control method of the aircraft comprises the steps that the rotating speeds of the first propeller and the second propeller are controlled to be the same, and the first rotor wing mechanism and the second rotor wing mechanism incline towards the flight direction of the aircraft or the axial directions of the first propeller and the second propeller are parallel to the gravity direction. The aircraft adopts a diagonal asymmetric two-rotor layout, so that the effects of higher efficiency, large rotor size, high cruising ability and no need of changing a propeller pitch and a variable pitch mechanism are realized, and the aircraft has the advantages of simple structure, higher reliability and the like. Flight actions can move independently, decoupling between executing mechanisms is achieved, the aircraft is easy to control, and the difficulty of flight control program writing is reduced.

Description

technical field [0001] The invention relates to the technical field of flight equipment, in particular to an aircraft and a control method for the aircraft. Background technique [0002] At present, in the field of unmanned aerial vehicles and manned autonomous aircraft, the number of rotors / propellers of a rotorcraft with vertical take-off and landing capability will not be less than two, which is the minimum number to ensure that the aircraft is controllable. For a propeller-driven aircraft, under the same power, due to the influence of aerodynamic efficiency, the fewer propellers and the larger the propeller size, the greater the total lift efficiency. At present, unmanned aerial vehicles and manned autopilot aircraft generally adopt the layout of quadrotor or more. Simple and safe. The aircraft with two rotors is a helicopter, and its structure has many types: a tail rotor and only one main rotor; Since the helicopter realizes maneuvering by changing the periodic pitc...

AI Technical Summary

Problems solved by technology

Since the helicopter realizes maneuvering by changing the periodic pitch of the propeller, the mechanical structure is complicated and the control is difficult, and the requirements for the operator and the flight controller are high.

In addition, the self-stability of the helicopter with the above two rotor structures is not good. Except for the coaxial twin propellers, it is difficult to maintain a stable flight state without the intervention of the operator and the flight controller.
