Engine special for unmanned aerial vehicle

Abstract

The invention provides a special engine for unmanned aerial vehicles, which relates to the technical field of unmanned aerial vehicles. The pinion gear and the bull gear are evenly distributed in a star-shaped arrangement, the pinion gear meshes with the bull gear, the drive unit drives the pinion gear to rotate, and the number of drive units is the same as that of the pinion gear. The large gear provides power for the drive shaft; the engine of the present invention has a compact structure, takes up little space, and is light in weight. When a certain drive unit is damaged, other transmission units can still continue to work, and then the engine can continue to work, which greatly improves the performance of the engine. The stability of the drone.

Description

Technical field [0001] The invention relates to the field of drone aviation technology, in particular to a special engine and engine block for drones. Background technique [0002] UAVs have a wide range of uses and varieties. A reasonable development route for UAVs should be formulated, and the development strategy of UAV power devices should be rationally planned. Especially UAV power devices, such as small and medium-sized pistons and turbofan engines, should be regarded as important. Among the most important, the choice of the type of UAV engine is not only related to the performance required by the UAV, but also related to the technical level of the engine, the development schedule requirements and the user's economic endurance. Judging from the current situation of the UAV power plant in service, the piston engine is suitable for low-speed, low-to-medium-altitude reconnaissance, surveillance UAVs and long-endurance UAVs. The take-off mass of the aircraft is small, generally...

AI Technical Summary

Problems solved by technology

Traditional UAVs do not have a professional power source in the field of general aviation, and their power methods basically do not have the ability to re-start in the air. The engine is likely to fail after a long period of operation, or it is directly parked. The engine suddenly stops and the aircraft loses power and crashes, causing The loss of airborne equipment may seriously injure people and property, and the reliability is poor, especially in high-altitude operating environments, where the probability of engine shutdown is high, and the safety of drones cannot be guaranteed.
