对某型多管火箭武器减少试验用弹量的仿真

采用系统仿真技术对某型多管火箭武器系统减少试验用弹量进行研究，首先给出确定1组非满管用弹量的方法，然后对满管和非满管情况分别建立以下模型进行仿真计算：建立燃气流模型，计算燃气射流冲击发射装置迎气正面的作用力和作用力矩；建立发射动力学模型，对发射过程建模和分析，得到炮口起始扰动的角位移和角速率；建立外弹道模型，即在发射动力学得到的火箭炮炮口参量下，进行火箭弹炮口扰动的转化，进而进行射击密集度的计算。最后进行置信度检验。仿真结果表明，将1组齐射40发减少到1组齐射12发，密集度指标无显著性差异。

Simulation on Decreasing Ammunition Consumption for Test of Some Multiple Launch Rocket System

A method of decreasing experimental ammunition consumption was studied with a systemic simulation method for a multiple launch rocket system.First,the method to determine a group of partial loaded ammunition was given.Second,the cases of fully loaded ammunition and partial loaded ammunition were simulated and calculated respectively by the following models: 1) a burning gas flow model used for calculating the force and moment generated by burning gas jet impinging of launch device;2) a launch dynamic model used for analyzing and modeling the annular displacement and velocity;3) an exterior ballistic model used for calculating the firing dispersion based on the barrel parameter results from a launch dynamic analysis.Finally,a verification of degree of confidence was done.The simulation results show that there is no marked difference for dispersion index if the ammunition is reduced from forty salvo to twelve salvo.
