Aircraft with four fixed rotor wings

Abstract

The invention discloses an aircraft with four fixed rotor wings. The aircraft comprises a fuselage, rotor wing arms and rotor wing power devices. Four rotor wing arms are arranged on four corners of the fuselage symmetrically; the four rotor wing arms and the fuselage are combined to form a cross structure; one rotor wing power device is fixed to each rotor wing arm; each rotor wing power device is composed of a cylindrical shell, a battery, a direct current motor, a speed governor and one rotor wing; the cylindrical shell is arranged at one end of the corresponding rotor wing arm and integrally formed with the corresponding rotor wing arm; the batteries, the direct current motors and the speed governors are fixed into the cylindrical shells; the batteries are used for providing power supplies for the direct current motors; the speed governors are used for adjusting the rotation speeds of the direct current motors; the direct current motors drive the rotor wings to rotate through transmission mechanisms. The safety and reliability of the aircraft are higher.

Description

technical field [0001] The invention relates to an aircraft, in particular to a quadrotor aircraft. Background technique [0002] Existing aircraft has the following defects: [0003] One is the use of two or more rotors that can turn, so there are disadvantages of complex structure, low safety and reliability; the other is that the communication module is easily interfered by the circuit board in the fuselage, thus affecting the normal operation of the aircraft; three It is relatively large in size and takes up a lot of space, so it is inconvenient to carry and transport; fourth, the load of the power equipment is determined, and different power equipment cannot be changed according to the actual body weight. Some of the retrieved patent documents are as follows: [0004] The State Intellectual Property Office published a patent with the publication number CN203294313U on November 20, 2013, and the patent name is a police four-rotor unmanned aerial vehicle. cover and GPS...
