摘　　要：研究了一种可以快速加压的气动灭火炮击发装置。采用伴随管随动发射,解决了高压气体发射击发时膛内发射气压需要瞬态达到气室压力的难题。建立了击发过程动力学模型和膛内气体参数模型,给出了击发过程灭火弹运动方程。通过对击发过程进行仿真分析,得到了击发过程膛内气体参数变化特性。研究了不同击发角对击发特性的影响,得到了最优击发角。通过MATLAB软件对击发装置的撞击过程进行了校核。研究结果表明,伴随管式击发装置能有效地解决膛内发射气压瞬态达到气室压力的要求。A quick pressing firing mechanism of the pneumatic fire-extinguishing cannon is studied, in which an associated tube is used for servo launch, solving the problem of that the launch gas pressure in the bore is required transiently to achieve the pressure in the gas chamber while launching. A dynamic model of firing process and a parameter model of gas in the bore are established, and a motion equation of projectile during firing is given. The variation characteristics of gas parameters in the bore are obtained by the simulation analysis of firing process in MATLAB environment. The effect of different firing angles on the firing characteristics is studied, and the optimal firing angle is obtained. The impact process of the firing mechanism is verified by using the software. The result shows that the firing mechanism with associ- ated tube can be used effectively to solve the problem of high-pressure gas reaching the total launching pressure in the chamber transiently.
