Abstract

The invention provides an auxiliary power device for ejection. The device comprises: a negative pressure cylinder provided with a first cavity and a second cavity which are not communicated with each other, wherein the first cavity is communicated with the outside, and the second cavity is communicated with vacuum equipment; a driving rod arranged in the first cavity in a sliding manner, and used for compressing the second cavity; and an ejection track, wherein the included angle between the ejection track and the horizontal plane is an acute angle, a pulley is slidably connected to the ejection track, and the unmanned aerial vehicle is placed on the pulley. The driving end of the driving rod is connected with the tackle through a transmission mechanism, and the driving rod is used for pulling the tackle to move along the ejection track. The ejection device is simple in structure, drives the unmanned aerial vehicle to take off through negative pressure, does not need fuel, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of catapults, in particular to an ejection auxiliary power device. Background technique [0002] In areas with complex terrain, islands, ships at sea, and remote areas, it is necessary to use unmanned aerial vehicles for intelligence reconnaissance, electronic countermeasures, communication relay, military surveying and mapping, weather detection, strike effect assessment and other tasks, as well as geological and landform surveying and mapping, forest fire prevention, radiation, etc. Detection, emergency relief, crop yield estimation, environmental monitoring, resource exploration, etc. [0003] Catapult takeoff can achieve a shorter length of catapult takeoff than rolling takeoff, thereby improving the cruising time and range of the UAV. At present, ejection takes off by installing the UAV on the launch frame, with the help of ejection devices such as booster rockets, high-pressure gas, and draglines; the...
