某转管机枪导气装置的动力学分析

确定气室压力变化规律的方法中,有一类是在实验和理论计算的基础上,给出经验公式,称为经验法;另一类是应用气体动力学和热力学理论,建立气室压力变化规律的理论公式,称为理论计算法。分别运用2种方法,通过对某内能源三管转管机枪的导气装置进行动力学分析,确定武器在使用过程中导气室内的压力变化规律并分析影响其压力变化的主要结构因素,为内能源转管机枪的参数设计提供理论依据。

Analysis on Dynamics of a Gatling Gun's Airway Equipment

Among the measurement methods for air compartment's pressure variation rules, one is called "The experience method"-deduces the experience formula based on experiments and theoretic calculation; and the other is "The theoretic calculation method"-uses theories of aerodynamics and energetics to build theoretic formula for air compartment's pressure variation rules. The two methods were respectively used to make dynamic analysis for air compartment of a certain three-tube Gatling gun with inner energy sources, while ensured the changing rule of pressure in airway equipment while weapons are firing, then analyzed the key structure elements which cause the change of the pressure, thus provide a theoretic basis for parameter design of gas operated Gatling gun with inner energy sources.
