Abstract

The invention discloses a multi-rotor aircraft, which includes a power assembly, a rotor assembly, a fuselage and a fuselage. Several arms are arranged on the fuselage, and a rotor assembly is respectively arranged on each fuselage. The power assembly is arranged on the fuselage. , the output main shaft of the power assembly is branched into several transfer outputs through the transfer assembly, and the transfer output is connected to the rotor assembly through the arm transmission part arranged along the arm, and all the rotor assemblies are driven by the same power assembly with the same The rotation speed rotates, and the rotor assembly is an adjustable pitch assembly to regulate the pitch during the rotation to control the flight attitude and motion. The invention adopts a group of power components to simultaneously drive a plurality of rotor components to work, all the rotor components have the same rotational speed, and the pitch is changed under the condition of constant rotational speed to adjust the lift of each rotor component, thereby controlling the attitude and movement of the aircraft, which is beneficial Enlarging the diameter of the rotor can effectively improve maneuverability, wind resistance and flight performance.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a multi-rotor aircraft. Background technique [0002] The existing multi-rotor aircraft is usually a variable-rotor multi-rotor aircraft. The aircraft is provided with more than four pairs of fixed-pitch rotor assemblies. The rotor assemblies are evenly distributed with the center of mass of the aircraft as the center of the circle. In the opposite direction, each rotor assembly is provided with a motor to drive the rotor to rotate to generate lift. Since the rotor assembly has a fixed pitch, the lift of each rotor assembly is changed by changing the rotational speed of the motor to realize the control of the attitude and motion of the aircraft. Increase the lift force by increasing the speed of all motors by an equal amount, causing the flight height to increase; reducing the speed of all motors by an equal amount reduces the lift force, causing a decrease in the flight height...
