| 目的 解决无人机回收系统因存在操作不当，引起减速伞的牵引钢丝绳断裂，导致无人机无法正常伞降问题。方法 将回收系统减速伞的拉断绳加上插销封包方式改为拉断绳封包方式，将减速伞舱内固定工艺改为舱顶固定方式，从根本上避免因操作问题导致回收失效的情况。结果 地面静拉试验表明，优化后的减速伞封包方式可以实现减速伞正常解封。冲击试验表明，优化后的减速伞固定工艺可以牢靠固定。结论 优化后的减速伞封包方式和固定工艺符合无人机回收系统使用要求，并且提高了伞降的安全性。 |

| Objective To solve the problem that improper operation of UAV′s retrieving system causes the fraction of conveying rope of drag parachute, leading to parachute failure. Methods The packet mode was changed from latch plus brake rope to break rope and the fixing process was changed from the middle part of recovery package to the top of recovery package, to avoid retrieving failure caused by improper operation. Results The static tension tests showed that the drag parachute could be unsealed. The impact tests indicated that the drag parachute could be fixed firmly after the packet mode and the fixing process were optimized. Conclusion The packet mode and the fixing process after optimization meet the operation requirement of UAV′s retrieving system. It improves the security of parachute landing. |
