The invention relates to an emergency parachute landing system for a light and small multi-rotor unmanned aerial vehicle. The emergency parachute landing system comprises a brake parachute assembly, a power source assembly and a structure assembly. The structure assembly is used for placing the brake parachute assembly and the power source assembly. The brake parachute assembly is used for reducing the landing speed of the failed unmanned aerial vehicle to a specified requirement; the power source assembly adopts a vehicle-specification-level gas generator MGG as a power source and is used for popping the brake parachute assembly out of the cylinder body, and it is ensured that a brake parachute in the brake parachute assembly is straightened and opened. The device has the advantages of being low in parachute opening height, low in landing speed, high in reliability, low in cost, low in self weight and wide in environment adaptation range, the parachute can be opened under the condition that the parachute canopy of the brake parachute is completely soaked, and the emergency recovery requirement of the current light and small multi-rotor unmanned aerial vehicle is met.
本发明涉及一种轻小型多旋翼无人机应急伞降系统,包括:减速伞组件、动力源组件、结构组件;所述结构组件用于放置减速伞组件和动力源组件。所述减速伞组件用于将出现故障的无人机的着陆速度减速到规定要求下;所述动力源组件采用车规级别的气体发生器MGG作为动力源,用于将减速伞组件弹出筒体,确保减速伞组件内的减速伞拉直开伞。本发明具有开伞高度低、着陆速度低、可靠性高、成本低、自身重量低、环境适应范围广,可在减速伞伞衣全部浸湿的条件下开伞,满足目前轻小型多旋翼无人机的应急回收需求。
