Multi-rotor aircraft

Abstract

The invention discloses a multi-rotor aircraft which comprises a power assembly, rotor assemblies, a fuselage and arms, the fuselage is provided with a plurality of arms, each arm is provided with a rotor assembly, the power assembly is arranged on the fuselage, and an output main shaft of the power assembly is branched into a plurality of transfer outputs through transfer assemblies. The transfer output is in transmission connection with the rotor assemblies through arm transmission parts arranged along the arms, all the rotor assemblies are driven by the same power assembly to rotate at the same rotating speed, and the rotor assemblies are propeller pitch adjustable assemblies so as to control the flight attitude and motion by adjusting and controlling the propeller pitch in the rotating process. According to the multi-rotor aircraft, a group of power components are adopted to simultaneously drive a plurality of rotor components to work, the rotating speeds of all the rotor components are the same, and the pitch is changed under the condition that the rotating speeds are not changed so as to adjust the lift force of each rotor component, so that the attitude and movement of the aircraft are controlled, the diameter of each rotor is favorably increased, and the maneuverability, the wind resistance and the flight performance can be effectively improved.

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...
