摘要 以一维非定常理论分析计算了航炮气体减震器的气体动力学特性;对导管和减震器内气流分别建立了力学模型,并提出了数值解法和实验与计算结果的分析比较。所提出的计算方法对枪、炮上的气体装置都有实用参考价值。 Based on unsteady one-dimensional gas dynamic theory, this paper gives an analysis of the gas dynamics characteristics of the gas buffers in gas-operated aircraft weapons. Models for the gas flow in the duct and buffer are suggested and numerical solutions given. Comparison and analysis between the computed and experimental results are then given. The proposed method will prove to be helpful in calculations for gas devices in guns.
