针对战斗部需要在较小开伞过载条件下工作的特殊要求,设计了过载动态测试装置,完成了战斗部开伞过载动态测试试验,记录了战斗部从开舱分离至降落伞完全展开过程的过载数据曲线。试验结果表明:动态测试开伞过载的方法可行,可获得有效的过载曲线数据。根据试验数据,不仅可推导降落伞分离、伞绳展开、伞绳拉直、伞衣充气展开的全过程,而且为战斗部所受过载评估和降落伞强度设计提供了数据支撑。
In view of the special requirements that warheads need to work under the condition of small parachute overload, an overload dynamic test device is designed to complete the dynamic test of overloading of the parachute department and record the overloading of the warhead from the open space to the full deployment of the parachute Data curve. The test results show that the method of dynamic testing of the overload of parachute is feasible and effective overload curve data can be obtained. According to the experimental data, it can not only deduce the whole process of parachute separation, unfolding of parachute, straightening of umbrella straws, inflation of parachute, but also provide data support for overloading assessment and parachute strength design of warhead.
