1.绪言本报告主要涉及到作为垮音速气体炮基础的气体动力学理论。参考了西格尔(Seigel)关于非稳流气体流动的基础理论。西格尔已将这一理论应用于以运动的活塞来压缩气体的二级高速发射装置。更重要的是,西格尔已给出了有关单级气体炮(例如本报告所考虑的)理论的全面概括。
1. INTRODUCTION This report mainly deals with the gas dynamics theory that is the basis of the canonical gas gun. Reference is made to Seigel’s basic theory of unsteady gas flow. Siegel has applied this theory to a two-stage high-speed launcher that uses compressed air to move the piston. More importantly, Siegel has given a comprehensive overview of the theory of single-stage gas guns (such as considered in this report).
