| Abstract: |
| 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. |
