某型火箭包延寿研究

The Research to Postpone Life of a Seat Ejection Rocket

通过对火箭包的结构进行分析,确定薄弱环节,对整体防松和点火管密封性进行了必要的结构改进。对装机退役后的火箭包进行了装药分析和与寿命有关的试验,根据试验情况确定其寿命年限。试验结果表明,改进后的火箭包内弹道性能一切正常,充分证明了改进工作是正确合理的。

According to analyze the structure of survival rocket and identify its vulnerable spots, necessary structural improvements are put on overall lock and the hermeticity of igniter tube. The charge analysis and lifetime related tests are put on retired survival rocket to identify its life duration by test condition. The test result shows that the ballistic capability inside improved survival rocket is normal which fully proves the improvement is reasonable.
