Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a fuel-powered unmanned aerial vehicle. Background Art

[0002] Fuel UAV is a new type of UAV. It uses gasoline engine as power source, has high thrust-to-weight ratio and endurance, can perform tasks for a long time, and is suitable for a variety of scenarios. Fuel UAV is mainly composed of frame, gasoline engine, remote control module, flight controller, GPS module, camera, etc. The gasoline engine is the power source of the UAV, the remote control module is used to control the flight of the UAV, the flight controller is used to adjust the flight attitude of the UAV, the GPS module is used for positioning and navigation, and the camera is used to shoot the images or videos required for the mission. The gasoline engine is the core component of the gasoline UAV. It generates power by burning gasoline, and the power is transmitted to the propeller through the transmission system to generate thrust to make the UAV fly. The flight controller controls the flight attitude of the UAV by adjusting the speed of the gasoline engine and the speed of the propeller. The GPS module is used to obtain the location and speed information of the UAV, automatically plan the path and control the flight of the UAV through the algorithm. Fuel UAV is gradually widely used due to its excellent endurance.
