再入弹道六自由度面向对象仿真研究

Object oriented simulation for six freedom degree reentry trajectory

对再入飞行器弹道参数的六自由度仿真是对其研究和设计的重要手段,基于Matlab的仿真存在速度较慢和扩展性较差的困难。本文根据再入弹道方程,进行了六自由度再入弹道仿真研究。整个仿真软件采用面向对象思想进行设计,使用标准C++语言实现,使得仿真系统具有较好的可扩展性、可复用性。基于面向对象思想的设计使得该系统可以方便地进行二次开发,也可以外接仿真或实物传感器,方便了对再入飞行器研究和设计。

In the study and design of reentry object, simulation for six freedom degree reentry trajectory is very important, whereas the simulation based on Matlab is slow and lack of extensibility. The simulation for six freedom degree reentry trajectory was studied based on the reentry equations set. The simulation software was designed by Object-oriented method, and implemented by standard C＋＋. The simulation system performs well on extensibility and reusability. Based on the Object-oriented design, the system can be easily developed secondarily, and can be plugged with simulation or physical sensors, which is convenient for the study and design of reentry object.
