基于诱饵出管安全性的内弹道智能控制研究

Research on intelligent control of the internal ballistic based on launch safety of the decoy

诱饵发射装置发射诱饵时,出管速度是一个重要指标,速度越低其出管安全性越危险,速度太高则存在较大发射噪声,因此研究一种有效方法确定合适的出管速度有重要意义。为满足能量利用最优,不同深度下实现上述出管速度还需对内弹道进行智能控制。本文基于刚体运动六自由度模型进行理论计算,对诱饵出管外弹道特性及出管安全性进行研究;建立某气动不平衡式发射装置“高压气瓶-控制阀-诱饵发射管”系统内弹道模型,为内弹道智能控制奠定应用基础。研究结果表明艇速越快,发射诱饵时安全离艇所需的出管速度要求越高。通过采用多元拟合方法,获得了控制阀芯运动速度控制律与安全离艇出管速度和发射深度之间的关系式,适用于内弹道智能控制研究。

Terminal velocity of the decoy during launch process is a key indicator,particularly the lower the speed,the more dangerous it is to guarantee safety as well as the higher the speed,the louder the emission noise appears.Thus,it is of great significance to study an effective method to decide the terminal velocity of the decoy.In order to realize the above terminal velocity of the decoy at different depths based on optimization of energy utilization,the internal ballistic must be controlled intelligently in launch process.In this paper,the calculation is carried out to obtain the external ballistic characteristics and the launch safety of the decoy based on the motion theory of 6DOF model of rigid body.According to a pneumatic unbalanced launcher which includes the systems of the high pressure gas bottle,the control valve and the tube,the model of internal ballistic is established,which is the foundation of intelligent control of the internal ballistic.The results show that the higher the velocity of the submarine,the higher the velocity of decoy is required to ensure the launch safety.Finally,by means of multivariate fitting,the motion law of the spool related to terminal velocity of the decoy and the depth of the launch is obtained as instruction to guide the research on intelligent control of the internal ballistic.
