Problems solved by technology

Although this solution can enable the fuselage to generate a certain lift and improve the performance of the aircraft, but during the flight, when the flight speed changes, the windward angle of the fuselage will also change, and the faster the speed, the greater the forward tilt angle of the fuselage. , so that the flight resistance will be greatly increased, and the changes to the performance of the quadrotor aircraft will be very limited.

Abstract

The invention provides a rotated quadrotor, and belongs to the technical field of aircraft design. The rotated quadrotor comprises flying rotor wings, brushless direct current motors, a fuselage, a canopy, undercarriages, a power supply unit, a flight control system, fixing tubes, a rotated rocker arm, a connecting rod, a rotated steering engine, rotor wing arms, and round heads. According to the rotated quadrotor, rotating angles of the four flying rotor wings in the front-back direction are controlled to as to realize forward flying or backward flying; installation angles of the flying rotor wings are changed so as to realize forward flying of the four flying rotor wings, maintain level condition of the fuselage, ensure that the best aerodynamic performance of the quadrotor is maintained all the time, and the maximum lifting force of the fuselage is induced, increase flying speed of the quadrotor, prolong flight duration, and improve wind resistance, operation capability, and efficiency.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, in particular to a tilting quadrotor aircraft. Background technique [0002] Quadrotor is an aircraft that can take off and land vertically with four rotor shafts. Electric motors on each shaft rotate to drive the rotor to generate thrust. The four rotors are evenly distributed around the machine body, and are arranged in pairs in forward and reverse directions. Various flight maneuvers are realized by changing the rotational speed between different rotors. [0003] Because of its simple structure, stable flight, easy operation, and convenient portability, multi-rotor aircraft, especially quad-rotor aircraft, have been widely used in various fields at home and abroad in recent years. Compared with traditional helicopters, it has many advantages: its rotor collective pitch is fixed, and its structure is simple. The blades of each rotor are relatively short, and the linear velocity at t...
