Oil and electricity hybrid power multi-rotor aircraft

Abstract

The invention provides an oil and electricity hybrid power multi-rotor aircraft which comprises an oil and electricity compound rotor assembly, an aircraft body bracket, a control cabinet, a battery pack, a fuel tank and an undercarriage. The oil and electricity compound rotor assembly is composed of engine rotors and motor rotors. The engine rotors provide main flying power for the aircraft, and the motor rotors flexibly adjust change of lift force of the oil and electricity compound rotor assembly. The oil and electricity hybrid power multi-rotor aircraft has the advantages that multiple fuel oil engines are adopted to serve as the main power, the time of endurance is long, and meanwhile the engine rotors are adopted to flexibly adjust the flight attitude. The engine rotors and the motor rotors can be controlled respectively and are standby power for one another, and the standby power can be adopted for safe landing when a fault occurs in the air.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an oil-electric hybrid multi-rotor aircraft. Background technique [0002] The multi-rotor aircraft is an aircraft with simple structure, flexible control and stable flight attitude. Generally, there are three-axis, four-axis, six-axis, eight-axis and other different types. Thanks to the development of micro-electromechanical and sensor technology in recent years, multi-rotor aircraft are widely used in aircraft model, aerial photography platform and other fields. The multi-rotor aircraft senses the flight state through various sensors, and sends rotational speed commands to the rotor motor through the microprocessor to adjust the different flight attitudes of the aircraft. [0003] At present, in order to obtain a stable flight attitude for a multi-rotor aircraft, various sensors are required to accurately perceive the aircraft state, and the microprocessor sends a rotational...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is that the failure rate of the 1 engine is relatively high. Once the engine fails, multiple main rotors will lose power, resulting in the main power loss of the aircraft. This is too risky for flying occasions with high safety requirements, such as manned. aircraft

2 The engine power is transmitted to multiple main rotors through the transmission mechanism, which inevitably brings about a loss in efficiency, which is not as efficient as direct connection

3Complicated transmission mechanism will occupy the space of the fuselage and increase the failure rate

4 If the engine for manned use occupies the middle position of the fuselage, it is not conducive to the location of the cabin, because it is closer to the passengers, the noise and vibration will have a greater impact
