Abstract

The invention provides a multi-rotor craft which comprises rotor assemblies, rotor supports and a rotor support base. The rotor assemblies are movably connected to the rotor supports. The rotor supports are movably connected to the rotor support base. The flight posture is adjusted by means of rotation of all the components. Controllable limiting devices are arranged at the tail ends of the rotor supports and in the rotor support base so that rotating and fixing of rotors and the rotor supports can be controlled, and the structure of the multi-rotor craft is changed to handle with different flight task requirements. Composite rotor assemblies composed of engines and motors are adopted, so that the beneficial effects that power of the engines is lasting and the response speed of the motors is high are achieved. The multi-rotor craft has the beneficial effects that the multi-rotor craft has a plurality of flight modes, the engines can be independently utilized as power, or the engines and the motors can be utilized at the same time as power, and the multi-rotor craft is high in endurance, large in load, fast in response and high in safety performance and achieves dual-power backup.

Description

technical field

[0001] The invention relates to the technical field of aircraft, in particular to a multi-rotor aircraft. Background technique

[0002] Multi-rotor aircraft is an aircraft with simple structure, flexible control and stable flight attitude. Generally, there are different types such as three-axis, four-axis, six-axis, and eight-axis. Thanks to the development of micro-electromechanical and sensor technologies in recent years, multi-rotor aircraft have been widely used in fields such as model aircraft and aerial photography platforms. The multi-rotor aircraft perceives the flight state through various sensors, and sends speed instructions to the rotor motor through the microprocessor to adjust different flight attitudes of the aircraft.

[0003] At present, in order to obtain a stable flight attitude for a multi-rotor aircraft, various sensors need to accurately sense the state of the aircraft, and the microprocessor sends speed instructions to the rotor motor...
