直升机仿真模拟训练软件系统设计实现

摘要

针对直升机仿真与地面模拟训练的需求,以VC++和Vega为开发工具,研制了一套具有三维视景显示功能的软件系统.通过编写直升机各执行机构的递推运算程序实现直升机模型的解算,用MFC设计直升机“操纵台”与“驾驶杆”界面,在Vega配置的视景仿真环境中显示直升机飞行姿态,以GDI为辅助工具编写虚拟仪表和曲线显示窗口,实时显示直升机姿态角、航向角和速度等飞行数据,实现了直升机仿真与模拟训练功能.实际运行结果表明,该系统仿真效果逼真,达到了设计要求,具有较好的实用性.%According to the requirements of helicopter simulation and training, a 9et of software system with three - dimension visual display function was developed based on VC + + and Vega. In order to realize the function of helicopter simulation and training, the solution of the helicopter model is achieved by the recursive operations program of the actuators, the helicopter " console" and " column" ' interfaces are designed based on MFC, the flight attitude is displayed in the visual simulation environment configured in Vega,the flight data such as attitude angles,heading angle and velocity is displayed in real time through virtual instruments and curve display windows which are designed by GDI as the assistant tool. It is shown that the simulation results are realistic, and the system achieves design specification that is very practical.
