The invention discloses a starting device of a small unmanned aerial vehicle engine, and relates to the technical field of structural design of aircraft ground auxiliary appliances. The starting device of the small unmanned aerial vehicle engine is used for starting the engine of a small unmanned aerial vehicle on the ground. An electric starter is fixed on an upper frame which is hinged to a lower frame through a wheel axle; one end of an upper supporting rod is hinged to the upper frame through a first hinge pin, one end of a lower supporting rod is hinged to the lower frame through a second hinge pin, and the other end of the upper supporting rod is connected with the other end of the lower supporting rod through a third hinge pin; a locking sleeve is arranged on the upper supporting rod. Due to the fact that the starting device of the small unmanned aerial vehicle engine is used for starting the small unmanned aerial vehicle, the starting process of the engine is made to be safer and more reliable, the occupied space can be reduced through folding, and transportation and storage are facilitated; in addition, by means of the adjustment of the installation height of the electric starter on the frame, the starting device can be suitable for the unmanned aerial vehicle with different types, and the cost of the ground maintenance of the unmanned aerial vehicle is made to be reduced.
Description
technical field [0001] The invention relates to the technical field of structural design of aircraft ground auxiliary equipment, in particular to a starting device for a small unmanned aerial vehicle engine. Background technique [0002] The layout of double tail braces is widely used in small unmanned aerial vehicles. Small unmanned aerial vehicles with this layout are generally equipped with a single tail-propelled piston propeller engine to allow space in the front of the fuselage, which is convenient for photoelectric pods and other effective load loading. However, this caused certain difficulties to start the engine at the rear of the fuselage. [0003] In order to reduce the weight as much as possible and improve the power-to-weight ratio, the piston engines used in small UAVs generally do not include a starting device. In actual use, the following three methods are usually used to start. One is to start the propeller manually by the ground crew; the other is to star...
