Problems solved by technology
During the flight, when the UAV changes direction, since the center of gravity is located below the UAV, the UAV will have a large inertia after the center of gravity deflects when turning, which is not conducive to control; in addition, the vertical structure, in the During repair and maintenance, it is necessary to remove multiple external parts before accessing the damaged parts, and disassembly and assembly are cumbersome

Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the orientation terms such as left, middle, right, up, and down in the examples of the present invention are only relative concepts or refer to the normal use state of the product, and should not be considered as restrictive .
[0031] Such as figure 1 As shown, an oil-electric hybrid unmanned aerial vehicle includes a frame on which a propeller, a fuel tank 2, an engine 4 and a control system are arranged, and the motor shafts provided by the propeller are located on the same circumference, and the The fuel tank 2 is located at the center of the circle.
[0032] which, combined with figure 2 and image 3 As shown, the frame includes a horizontal main frame and a subframe fixedly connected side by side, the propellers are fixedly connected to the main frame through machine arms, the fuel tank 2 and the engine 4 are located on the subframe, ...

The invention provides an oil-electric hybrid unmanned aerial vehicle. The oil-electric hybrid unmanned aerial vehicle comprises a vehicle frame, wherein propellers, an oil tank, an engine and a control system are arranged on the vehicle frame; motor shafts arranged by the propellers are positioned on the same circumference; the oil tank is positioned at the center of the circumference; the vehicle frame comprises a main frame and a sub-frame which are horizontally and fixedly connected in parallel, and the propellers are fixedly connected with the main frame through machine arms; and the oiltank and the engine are both positioned on the sub-frame, and the engine and the main frame are correspondingly positioned on the two sides of the oil tank. The large-weight oil tank is arranged at the center of the circumference where the motor shafts are located, so that the gravity center of a whole unmanned aerial vehicle body is close to the circumferential surface where the motor shafts arelocated and close to the center of the circle of the circumference. When the unmanned aerial vehicle turns and swings, the swing moment of the gravity center is small and the swing inertia is small, so that the unmanned aerial vehicle turns agilely, and the control is stable and convenient. In addition, since the oil tank is located at the center of the circle of the circumference where the motorshafts are located, when the amount of oil in the oil tank changes, the influence on the control over the propellers is less, and the flight stability of the unmanned aerial vehicle is increased.
Description
technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an oil-electric hybrid unmanned aerial vehicle. Background technique [0002] With the development of the UAV market in recent years, small UAVs have been used more and more widely in consumer and industrial fields due to their low cost and ease of use. The advantages of simple structure, easy maintenance and vertical take-off and landing are quickly recognized by the market. At present, multi-rotor UAVs are mainly electric, and the disadvantages of low energy density and short service life of batteries have seriously restricted their development in the fields of power inspection, logistics and transportation, public security and fire protection, agricultural plant protection, and surveying and mapping. The invention provides an oil-electric hybrid unmanned aerial vehicle. Compared with the traditional battery power supply, the use of oil-electric hybrid power can greatly improve th...
