Abstract

The invention relates to a multi-rotor aircraft, which comprises four main rotor systems, two auxiliary rotor systems, a body and a flying integrated system arranged in the body, wherein an original point of a coordinate system of the body is the gravity center of the aircraft; a z axis is vertical upwards; an x axis is vertical to the z axis and points to the front part; a y axis is determined by a right-hand rule; the four main rotor systems are respectively distributed inside four quadrants of an x-y plane of the body coordinate system; each rotary axis of the four main rotor systems and the z axis of the body coordinate system form an included angle theta, and a projection of each rotary axis on an x-o-y plane of the body coordinate system is overlapped with the projection of a connection line from a rotation center to the original point of the body coordinate system on the x-o-y plane of the body coordinate system. According to the invention, movement and gesture change of the aircraft can be achieved by adjusting rotating speed of the four main rotor systems and the two auxiliary rotor systems; and the aircraft can achieve the actions such as vertical take-off and landing, forward flying, reverse flying, hovering, rolling and the like, and the stability and the controllabitity are good.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a multi-rotor aircraft. Background technique [0002] Rotor-type aircraft with functions such as vertical take-off and landing and hovering not only play an important role in the military field, but also show great application potential in disaster scene rescue, dangerous environment detection, traffic surveillance or aerial photography, and have been widely accepted. focus on. [0003] At present, rotorcraft mainly include four structural forms: single-rotor (main rotor + tail rotor) helicopter, double-rotor (coaxial reverse propeller) helicopter, quad-rotor aircraft and six-rotor aircraft, such as the MH-16 helicopter of McDonnell Douglas , Russia's Ka-29 helicopter, Germany's Microdrone company, Canada's Dranganflyer company's quadrotor aircraft, etc. Single-rotor helicopters or coaxial reverse-rotor helicopters need tail rotors to eliminate the torsion produced by the rotors on the ...
