编制了固体火箭发动机性能预示软件 ,以美国的 AIM发动机和法国的 SEP发动机为例进行了比冲预示 ,并与美、英、法、德、意等国软件的预示结果进行了比较。计算表明 ,该软件达到了国外同等水平的预示精度 ,可用于导弹总体设计、发动机优化设计 The performance prediction software for solid rocket motor was developed. The specific impulse prediction was made by taking the AIM engine of the United States and the SEP engine of France as an example, and compared with the predictions of the software of the United States, Britain, France, Germany and Italy. The calculation shows that the software has reached the same level of foreign precision forecasting, can be used for the overall missile design, engine optimization design
