摘　　要：针对单组元推力器组件产品的测试数据出现“合格/不包络”现象,为更好地了解产品特性,提前发现产品风险点,文章在聚焦单组元推力器6项关键特性参数的基础上,利用47台已成功飞行的推力器组件的关键特性地面测试数据构建成功飞行数据包络线,选取单值控制图算法对待分析推力器的地面测试数据进行包络分析,发现该推力器的部分特性参数出现“合格/不包络”的情况;进一步检查发现该推力器性能不满足交付要求。以上方法运算简单,操作便利,有助于提前发现产品在生产流程中的薄弱环节,从而可尽早开展相应风险分析,提高产品可靠性。In view of the“qualified but non-enveloped”phenomenon in the test data of monopropellant thrusters,in order to better understand the product characteristics and to discover the product risk points in advance,this paper constructed the data envelope on the basis of focusing on six key characteristic parameters of monopropellant thrusters and by using the ground test data sets of the key characteristics of forty-seven successfully flown thrusters.The individual control chart algorithm was selected for the envelope analysis,and it was found that some characteristic parameters of the thruster appeared to be“qualified but non-enveloped”.Further inspection revealed that the performance of the thruster did not meet the delivery requirements.The above method is simple in calculation and convenient in operation,which may help to identify the weak links of products in the production process in advance,so that the corresponding risk analysis can be carried out as early as possible to improve the product reliability.
