Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] This case involves a variable-pitch multi-axis aircraft. On the one hand, a motor can simultaneously drive multiple rotors to rotate synchronously. On the other hand, the pitch of each rotor is variable. The structure is described in detail below through preferred embodiments.

[0024] ginseng figure 1 As shown, the variable-pitch aircraft includes a frame 10 , a drive system 20 and a variable-pitch rotor 30 mounted on the frame.

[0025] The support 1...

Abstract

The invention discloses a control device of a variable pitch aircraft. The control device comprises a first control rod; the first control rod controls the screw pitch of rotor wings of an aircraft and the rotation speed of a motor to increase synchronously at the first state, and controls the screw pitch of rotor wings of the aircraft and the rotation speed of the motor to increase synchronously at the second state. The invention also discloses a control method of a multi-rotor-wing variable pitch aircraft. According to the control method, when the climbing screw pitch of the aircraft needs to be increased, a flight controller controls the motor to improve the rotation speed and the torsional force correspondingly in a certain proportion. The mode is relatively high in efficiency, has moderate sensitivity and is easy to control.

Description

technical field [0001] The application belongs to the field of aerial photography, and in particular relates to a control method and a control device for a multi-rotor pitch-variable aircraft. Background technique [0002] Each axis of the multi-axis aircraft in the existing technical solution is composed of a corresponding propeller and a motor driving the corresponding propeller. The attitude maintenance and maneuvering action of the aircraft flight is to control the speed of each motor separately through the flight control system (the rotation directions of the various motors of the existing multi-axis aircraft are in pairs to counteract the spin torque) to achieve the attitude and action control of the aircraft of. The attitude of the vertical take-off and landing aircraft includes level and tilt. Maneuvering actions include level flight, ascent, descent, and spin (around its own Z axis, that is, the vertical axis of the horizontal plane of the body structure). The as...
