某无人机回收系统故障改进设计

Improvement Design for Fault in Recovery System of an UAV

目的解决无人机回收过程中,点火具工作失效,导致无人机坠毁的问题。方法对点火具工艺进行改进,点火具收口至管壳口部与定位环完全接触,在绸垫与管壳的接缝处用硝化棉胶液粘接。结果地面试验验证和空中飞行验证表明,改进措施有效,更改后的点火具工作稳定可靠。结论更改工艺后的点火具工作稳定,满足无人机回收系统使用要求,相比原状态提高了回收系统工作可靠性。

Objective To solve the problem of UAV crash caused by the failure of firing rocket igniter in UAV recovery.Methods The manufacturing process of ignition device was improved.The ignition device close to the mouth of the shell and the positioning ring was in full contact,and the joint between the silk pad and the shell was bonded with nitrocellulose glue.Results Ground tests and aerial flight tests showed that the improvement measures were effective,and the modified ignition devices were stable and reliable.Conclusion After changing the process,the ignition device is stable and meets the requirements of the UAV recycling system.It improves the reliability of the recovery system compared to the original state.
