Analysis on Internal Ballistic Property of Gas Piston Missile Wing Expanding Propulsion System

为了给某型燃气活塞式弹翼展开动力系统的研制和改进提供理论依据,根据弹翼展开机构的具体结构,考虑展开动力系统与展开执行机构之间的耦合联动关系及弹翼展开过程中的气动负载等,建立了该动力系统的内弹道性能分析模型并完成了性能计算,将计算结果与试验数据进行了对比分析,两者基本吻合。研究结果表明,该模型可为工程实践提供理论支持。

In order to provide theoretical reference for design and improvement of some gas piston missile wing expanding propulsion system, the coupled linkage between expanding propulsion system and executive mechanism as well as aerodynamic load during wing expanding etc. were considered based on structure of wing expanding mechanism. The internal ballistic performance analysis model of gas piston propulsion system was established and performance computation was conducted, and computation result was basically consistent with test data. The research result shows that the model can be theoretical support for engineering practice.
