Dual-turbine-shaft power unmanned helicopter

Abstract

The invention relates to a dual-turbine-shaft power unmanned helicopter. The dual-turbine-shaft power unmanned helicopter comprises a machine body, a main rotor and a power system for providing power for the main rotor, wherein the power system is a dual-turbine-shaft power system; the dual-turbine-shaft power system comprises a main reducing gear, two sets of turbine shaft engine systems and a controller in electric connection with the two sets of turbine shaft engine systems; the main reducing gear is provided with two power input terminals which are connected with the two sets of turbine shaft engine systems respectively; a power output terminal of the main reducing gear is connected with the main rotor. According to the dual-turbine-shaft power unmanned helicopter, not only can the internal space of a cabin be saved, but also the effective load mass can be increased, and the safety of the unmanned helicopter, ground staff and ground facilities can be guaranteed.

Description

technical field [0001] The invention relates to an unmanned helicopter, in particular to an unmanned helicopter powered by twin-engine turbine shafts. Background technique [0002] Unmanned helicopter refers to an unmanned, unmanned vertical take-off and landing rotorcraft that flies by radio remote control or autonomous control. It relies on electric motors or piston engines to drive the rotor to generate lift and control force, can take off and land vertically, hover in the air, and can fly flexibly in any direction. [0003] Unmanned helicopters play a unique role in modern warfare, economic construction, and daily life. Taking civilian use as an example, unmanned helicopters have the advantages of relatively low cost, no risk of casualties, strong survivability, good maneuverability, and convenient use. They are widely used in aerial photography, aerial photography, geological and landform mapping, forest fire prevention, Earthquake investigation, border patrol, emerge...

AI Technical Summary

Problems solved by technology

[0004] Existing unmanned helicopters are mainly driven by electric motors or piston engines. However, as users' demands on the load weight and endurance of UAV platforms continue to increase, the original power source can no longer meet the output power requirements of UAVs. , fuselage weight and other requirements: if the power of the motor is increased, the volume and weight of the onboard battery will also be greatly increased, which seriously reduces the payload of the drone; after the power of the piston engine is increased, the engine and The volume and weight of the supporting cooling system will also be greatly increased, and the engine vibration will be more severe

In addition, engine failure usually causes a single-engine UAV to crash directly. In addition to the damage of the UAV itself, it will also threaten the safety of ground personnel and property.
