外挂物与载机分离过程的数值模拟系统

简要介绍外挂物与载机分离（发射或投放）过程的数值模拟系统－－ＧＳＳＰ（２），它能快速、方便、有效地提供载机及外挂物气特性和外挂物分离后与载机的相对运动轨迹及姿态，为带外物飞机的设计和相容性研究提供了有效的手段，同时还简要描述本系统的３个系统及空程序的结构和数值模拟方法，最后，将数值模拟结果 洞实验结果作了比较，两者吻合较好。

NUMERICAL SIMULATION SYSTEM FOR EXTERNAL STORE SEPARATION FROM AIRCRAFT

The numerical simulation system CSSP(2) for external store launching and releasing from aircraft is presented briefly.This system provides a powerful tool for the compatibility design of aircraft with external store by calculating fastly,conveniently and effectively the relative trajectory and relative attitude of the store with respect to aircraft during the separation process. The architecture and the method of numerical simulation of the three subsystems and the controling program also are described.The comparision of the results from the numerical simulation with the results from wind tunnel experiments shows fairly good agreemet.
