摘要
本文建立了气枪枪管和气瓶内弹道的热力学数学模型。此外，这个热力学数学模型处理了气体通过活塞周围的环进入大气的质量流。以7.62 mm UK-59机枪和7.62 × 54 R弹药为例，对热力学数学模型和求解算法进行了验证和实验验证。本文的结论可用于类似武器吸尘抽气机枪气体推进结构的计算与设计。
The article describes a thermodynamic mathematical model of internal ballistics in the barrel and in the gas cylinder of a gas-operated gun. In addition, this thermodynamic mathematical model deals with the mass flow of gas through the ring around the piston into the atmosphere. The thermodynamic mathematical model and the solution algorithm are validated and verified experimentally on the example of a 7.62 mm UK-59 machine gun and 7.62 x 54 R ammunition. The conclusions of this paper are applicable to the calculation and design of the machine gun gas propulsion structure for similar weapons with dust gas extraction.
