| 摘 要： | 为研究再生式液体发射药火炮燃烧室的压力振荡,建立了燃烧室气体三维波动方程,给出了求解气体动态特征频率的表达式,在某一确定燃烧室容积下分析了燃烧室结构尺寸对气体动态特征频率的影响规律.通过分析气体动态特性在压力振荡抑制技术研究中的影响,给出了避开燃烧室压力振荡主频带的燃烧室半径与长度的比.研究结果表明,燃烧室气体多阶动态特征频率受到激励是RLPG燃烧室产生压力振荡的一个重要原因,通过合理设计燃烧室结构尺寸可以避免燃烧室气体多阶动态特征频率受到激励.

| Abstract: | To study the pressure oscillation in chamber of regenerative liquid propellant gun(RLPG),three-dimensional wave equation was established.Its expression was given and resolved.Given chamber volumn,the influence of configuration dimension of combustion chamber on dynamic characteristic frequency was analyzed.The ratio of the combustion chamber radius to the length to avoid pressure oscillation was given by analyzing the effects of gas dynamic characteristics on restraining pressure oscillation technique.The results show that the pressure oscillation in RLPG chamber is mostly caused by exciting multi-rank dynamic characteric frequencies,and that multi-rank dynamic characteristic frequencies of combustion chamber gas aroused can be avoided by reasonable design of configuration dimension of combustion chamber. |
