研究结果表明:气体动力载荷因素中,压力升高率和放热率是影响燃烧噪声的重要因素。
The result shows that the rate of pressure rise and the heat release are the main dynamic load factor that affects the combustion noise.
因为柯达火药在较高的压力下以较高的速度燃烧,所以必须使用一个溢流阀,以便当用气少时,能让所产生的部分气体排到大气中去。
Since cordite burns at a greater rate at a higher pressure a relief valve must be used to allow generated gas to escape to atmosphere at times when the demand is low.
通过对火炮膛内压力-时间曲线的再处理,研究发射药的气体生成强度,进而分析发射药装药的物理燃烧规。
In this paper, gas generating strength of propellant charge was studied on basis of retreating for bore pressure time curve, and physical firing law of propellant charge was analysised.
