Problems solved by technology

However, since multi-rotor aircraft are powered by batteries, and the total power consumption of multi-rotor aircraft is very large during use, multi-rotor aircraft powered by batteries generally have short battery life and small load capacity, which greatly limits the use of multi-rotor aircraft. performance and application areas
[0003] In order to overcome the shortcoming of the multi-rotor aircraft's short endurance time, various solutions have been proposed in the prior art: on the one hand, the fuel engine is used as the power, but the fuel engine cannot change the speed quickly, and the flexibility is limited; on the other hand, the balloon is used as the power. Auxiliary power, but the balloon auxiliary power is huge and is greatly affected by the wind; in addition, fuel cells are used as a power source, but the fuel cell technology is not mature enough to effectively solve the common problems of current multi-rotor aircraft

Abstract

The invention discloses a multi-rotor aircraft, which comprises an engine, a power rotor structure, an attitude rotor structure and a battery. The engine generates power by burning internal fuel. Thepower rotor structure comprises a power rotor and a transmission path, wherein the power rotor is dynamically connected with the engine through the transmission path; attitude rotor structure includesattitude rotor, attitude rotor motor and attitude rotor bracket. Attitude rotor is directly driven by attitude rotor motor. Attitude rotor is mounted on attitude rotor bracket. Attitude rotor motor is electrically connected with battery. The multi-rotor aircraft disclosed by the invention has the characteristics of long endurance time and high flexibility.

Description

technical field [0001] The present invention relates to the technical field of aircraft, and more specifically relates to a multi-rotor aircraft. Background technique [0002] At present, multi-rotor aircraft is an aircraft with simple structure, flexible control and stable flight attitude. Generally, there are different types such as 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. However, since multi-rotor aircraft are powered by batteries, and the total power consumption of multi-rotor aircraft is very large during use, multi-rotor aircraft powered by batteries generally have short battery life and small load capacity, which greatly limits the use of multi-rotor aircraft. performance and application fields. [0003] In order to overcome the shortcoming of the multi-rotor aircraft...
