Multi-power-source series-connection type hybrid power unmanned aerial vehicle and control method thereof

Abstract

The invention discloses a multi-power-source series-connection type hybrid power unmanned aerial vehicle and a control method thereof. The unmanned aerial vehicle comprises a vehicle body, a left wing, a right wing, a left aileron, a right aileron, a left flap, a right flap, an empennage, a left wing motor, a left wing propeller, a right wing motor, a right wing propeller, a standby propeller module, a horizontal stabilizer, a vertical stabilizer, an elevator, a rudder, an engine, a clutch, an inverter, a power generation / electric all-in-one machine, a storage battery pack, a super-capacitor,an oil tank, a temperature sensor, a pressure sensor, a state-of-charge estimation module and a control module. Enough cruising ability and high maneuverability of the unmanned aerial vehicle can be guaranteed; and meanwhile, the standby propeller module is arranged on the empennage, so when a driving mechanism of the unmanned aerial vehicle breaks down, an engine drives the standby propeller to drive the unmanned aerial vehicle, the situation that the system has a certain redundancy function is guaranteed, and the survival capacity of the unmanned aerial vehicle is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aviation aircraft, and specifically refers to a multi-power source serial hybrid unmanned aerial vehicle with redundant functions and a control method thereof. Background technique [0002] In recent years, insufficient fossil fuel reserves, global warming, and serious environmental pollution have attracted increasing attention. Since automobiles and airplanes are indispensable tools in business and military today, both of them generate a lot of fuel consumption and pollution. Under this opportunity, automobiles have taken precedence over airplanes to carry out an energy revolution. At present, automobiles have been developing in the direction of energy saving, low noise and low pollution, and have achieved considerable results. Among them, hybrid technology is the most mature. On the basis of ensuring the power of the car, the fuel consumption of the car is greatly saved, and the application of hybrid te...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a multi-power source series hybrid unmanned aerial vehicle and its control method to solve the problem of poor maneuverability of the series hybrid unmanned aerial vehicle existing in the prior art. , low survivability and other issues; the present invention not only ensures that the UAV can have sufficient endurance, but also ensures the high maneuverability of the UAV by setting three power sources of the engine, the battery and the super capacitor. There is a spare propeller module. When the UAV drive mechanism fails, the engine will drive the spare propeller to drive the UAV, ensuring that the system has a certain redundancy function, thereby greatly improving the survivability of the UAV.
