The invention relates to a multi-stage catapult rack for catapult-assisted take-off of an unmanned aerial vehicle. Comprising a base, an ejection guide rail, an ejection seat, an air reservoir, an air compressor and an air interchanger, airflow is blown to a turbofan to drive a second adjusting turntable to rotate, so that a gas storage cavity alternately provides compressed gas reaching the pressure required by ejection to a first transition box, and the compressed gas is ensured to be continuously output to the first transition box; under the action of an inner tooth type ratchet mechanism, air cylinders serving as ejection devices in the two side cavities alternately work to drive a winding roller to rotate, and it is ensured that the winding roller continuously rotates to wind a traction rope to eject the unmanned aerial vehicle out; the acceleration stroke of the ejection device on the unmanned aerial vehicle gets rid of the limitation of the telescopic stroke of a single air cylinder telescopic rod, it is ensured that the unmanned aerial vehicle can be accelerated and accelerated before the ejection base and the ejection guide rail are separated, and the acceleration peak value is reduced by improving the accelerated stroke, so that the acceleration speed is reduced in the acceleration process. The damage of the load to the unmanned aerial vehicle body and airborne equipment is avoided.

    本发明涉及一种无人机弹射起飞用多级弹射架;包括底座、弹射导轨、弹射座、储气筒、空气压缩机和换气装置;利用气流吹向涡轮风扇带动第二调节转盘转动使储气空腔交替向第一过度箱提供达到弹射所需压力的压缩气体,确保压缩气体持续向第一过度箱持续输出;在内齿式棘轮机构的作用,在两个侧空腔内作为弹射装置的气缸交替工作驱动收卷辊筒转动,确保收卷辊筒持续转动收卷牵引绳将无人机弹射出去;使弹射装置对无人机的加速行程摆脱单个气缸伸缩杆伸缩行程的限制,确保弹射座与弹射导轨分离之前均能对无人机进行加速,提升加速行程,通过提升加速的行程,降低加速度峰值,进而减小加速过程中,负载对无人机机身以及机载设备的损伤。
