摘要
文中根据机动再入末制导技术的特点,利用面向对象思想,设计了再入飞行器的仿真框架。在该框架中,状态变量及对应的右函数、空气动力、惯性测量系统、速率陀螺、导航方程、导引方程、执行机构等均作为独立的对象建模,坐标变换等常用算法也利用面向对象技术实现。在此基础上,利用VC++6.0语言开发了再入飞行器仿真系统,可以支持再入飞行器的分析、设计、试验等不同背景下的飞行性能仿真。
Based on the terminal-guiding technology of maneuvering reentry vehicles and object-oriented methodology, the paper put forward a general simulation frame about reentry vehicle. In this frame, they are modeled as independent classes such as state variables and their corresponding right function, aero dynamic, inertial navigation system, naviga- tion equation and actuators, and the arithmetic such as coordinate transform are implemented by object-oriented technique. So the frame is flexible. Based on the frame, the simulation system of reentry vehicle is developed by VC＋＋ 6.0 programming language. It can support flight performance simulation with various backgrounds.
