一种双级弹射作动筒对抛分离输出特性研究

Study on the Relative Separation Output Characteristics of A Double-stage Ejection Actuator

为满足武器系统低过载对抛分离功能要求,设计了一种对抛式双级弹射作动筒,基于零维内弹道理论建立了对抛式双级弹射作动筒内弹道模型,对其分离输出特性进行了仿真,并对内弹道模型的准确性进行了试验验证。结果表明,对抛式双级弹射作动筒内弹道模型准确可靠,压强仿真曲线与实测曲线基本吻合,分离输出参数仿真值与实测值基本一致,误差不超过5%。本研究能够为同类型对抛式双级弹射作动筒的设计提供理论指导。

In order to meet the requirements of low-overload relative separation function of weapon systems,a relatively separated double-stage ejection actuator was designed.Based on the zero-dimensional interior ballistic theory,an interior ballistic model of the relatively separated double-stage ejection actuator was established to simulate its separation output characteristics,and the accuracy of the interior ballistic model was tested and verified.The results show that the interior ballistic model of the relatively separated double-stage ejection actuator is accurate and reliable,and the pressure simulation curve is basically consistent with the measured curve.The simulated and measured values of the separation output parameters are basically consistent,with an error of less than 5%.This study can provide theoretical guidance for the design of relatively separated double-stage ejection actuator of the same type.
