考虑到气缸张开式尾翼启动时机与炮弹的内弹道性能密切相关，对某新型制导炮弹内弹道性能进行了研究，建立了内弹道一维两相流模型并采用了两阶精度的MacCormack差分格式对模型进行了仿真，得到了膛压、弹丸速度等随时间的变化规律曲线，分析了药厚、火药燃烧规律、弹丸阻力系数等因素对内弹道性能的影响。研究结果为进一步分析该新型制导炮弹气缸张开式尾翼气缸压力的变化规律提供了理论依据。

The interior ballistic performance for the guided projectile is studied and the one-dimensional two-phase flow model is established considered the important relationship between the cylinder-open fin's setup time and the interior ballistic performance. They are numerical simulated by two step MacCormack scheme such as the gun pressure and the projectile velocity. And it is analyzed that the powder thickness, powder burning law projectile resistance coefficient and other factors impact on the interior performance. The results provide the theoretical basis for analyzing the pressure of cylinder-open fin.
