The invention provides a bullet module based on a small unmanned aerial vehicle, the bullet module is mainly composed of four bullets, an external hanging device, a camera and an
electric arc generator, the core part of the bullet module is that the four bullets and a single bullet are of a disposable and integrated totally-enclosed structure,
gunpowder in the bullets is ignited by the
electric arc, the bullets are shot forwards after ignition, and the bullets are shot backwards after being ignited by the
electric arc generator. The gun body slides backwards to be separated from the module, the influence on flight of the unmanned aerial vehicle is small, and the gun body is provided with a small parachute and can be automatically opened to slowly land. The two bullets are the same in external dimension and comprise the
shotgun bullets and the armor-piercing bullets, the
shotgun bullets hit an aerial target, the armor-piercing bullets hit an overground target, and the
shotgun bullets and the armor-piercing bullets can be used in a
mixed mode when necessary. According to the technical scheme, the small unmanned aerial vehicle can
mount bullets which are light, high in precision and good in
controllability, and application of the small unmanned aerial vehicle in the aspects of military and armed police is greatly expanded.
