Problems solved by technology

This structure has low efficiency, small load, and unstable power. Especially in the process of descending, the speed must be reduced to reduce the lift of the rotor. The reduction of lift means that the ability to control the attitude of the aircraft is weakened, and the aircraft will sway. situation even out of control

Embodiment 1

[0030] control Figure 1-12 The implementation process of the present invention is described.

[0031] Variable-moment and large-load quadrotor aircraft, including: a fuselage, connected to the fuselage, four symmetrically distributed rotor arms, and rotors located on the rotor arms. Among the four rotors, the rotation directions of two adjacent rotors are opposite ; The included angle between each rotor blade 1201 and the horizontal plane can be adjusted to achieve the adjustable lift force, and then adjust the attitude of the aircraft.

[0032] Described rotor is driven by motor 701, and the rotational speed of each motor keeps consistent. Also includes: rotor blade angle adjustment mechanism, which includes: inertial navigator 401, four steering gears 601-1, 601-2, 601-3, 601-4 controlled by the inertial navigator, respectively connected to each steering gear The connecting rod 901, the rocker arm 1001, and the rectangular slider 1101.

[0033] The fuselage comprises: a ...

Abstract

The invention relates to a gyroplane and further relates to a variable-torque four-rotor aircraft with large load capacity. The variable-torque four-rotor aircraft with large load capacity contains a fuselage, four rotor arms which are connected with the fuselage and are symmetrically distributed, and rotors positioned on the rotor arms. Among the four rotors, two adjacent rotors rotate in opposite directions. The included angle of each rotor blade 1201 to the water level can be adjustable, thus making the lift force adjustable and further adjusting the attitude of the aircraft. According to the invention, operationality of the aircraft is substantially raised.

Description

technical field [0001] The invention relates to a rotorcraft, and further relates to a quadrotor aircraft with variable moment and large load. Background technique [0002] Existing multi-rotor aircrafts change the rotation speed of the rotors by adjusting the rotation speed of each motor to realize the change of lift force, thereby controlling the attitude and displacement of the aircraft. This structure has low efficiency, small load, and unstable power. Especially in the process of descending, the speed must be reduced to reduce the lift of the rotor. The reduction of lift means that the ability to control the attitude of the aircraft is weakened, and the aircraft will sway. The situation even got out of hand. Contents of the invention [0003] The object of the present invention is to provide a rotorcraft with an adjustable angle between the blade and the horizontal plane. [0004] Variable-moment and large-load quadrotor aircraft, including: a fuselage, connected to...
