| Abstract: |
| 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. |
