摘要
为实现冲击波尽量小的高效后坐,提出了定向反射膨胀原理,设计了相应的装置。运用一维准定常气体动力学理论,建立了气体动力学模型,根据实际情况选定模型参数进行数值分析,得到了装置减后坐效率及弹丸炮口初速等理论分析结果;根据理论分析结果确定了实验装置的基本参数,设计实验并在某30 mm口径的火炮上进行定向反射膨胀装置的实验验证。实验测试结果表明,理论分析结果与实验测试结果基本一致,验证了定向反射膨胀装置作用特性研究的正确性,为定向反射膨胀原理及装置的继续研究打下了基础。
To realize the high-efficient recoil with minimal shock wave,the principle of directional reflection expansion was proposed,and the corresponding device was designed. Based on the one-dimensional quasi-steady gas dynamics theory,the gas dynamics model was established. The model parameters were determined based on actual conditions,and the numerical analysis was carried out to obtain the results of the reduced recoil efficiency of the device and the initial velocity of the projectile. The basic parameters of the experimental device were determined based on the theoretical analysis results. The experiments were designed,and the experiments of directional reflection expansion device were carried out on a 30 mm caliber gun. The result indicates that the experimental results are roughly the same as the numerical analysis results,which confirms the correctness of this research. The result lays the foundation for the further research of the device.
