摘　　要：为降低枪械武器的发射后坐力,建立基于全可燃药筒、尾喷气体式无后坐力发射系统内弹道数值计算模型。分析尾喷气体式无后坐力发射系统工作原理与发射过程,建立发射过程中的内弹道模型,进行弹道系统参数设计与内弹道数值仿真。设计无后坐力发射弹道系统验证方案,进行内弹道试验,并将数值模拟结果与试验结果进行对比分析。结果表明,该模型能正确模拟发射过程中膛压变化。To reduce the launching recoil of firearms,a numerical calculation model of internal ballistics based on combustible cartridge and recoilless was established.The working principle and launch process of the rear jet gas recoilless launch system are analyzed,and the zero-dimensional interior ballistic model during the launch process is established,to simulate the performance of ballistic system.A recoilless launch trajectory system verification scheme was designed,and internal ballistic was conducted.The numerical simulation results were compared with the experimental results.The results indicate that the model can accurately simulate the changes in chamber pressure during the launch process.
