以开发一套直升机飞行模拟仿真系统为目的,对仿真应用系统开发中各种常见的建模和驱动技术尤其是动态仪表面板仿真模块进行了研究,提出了可行的实现方案;利用建模工具Creator对飞机、仪表和大面积地形进行了可视化建模,利用DOF(Degrees OfFreedom)技术实现了直升机旋翼、尾翼以及仪表指针的动态交互;基于VC++集成开发环境,应用Vega API编程技术实现了直升机视景仿真应用系统的全部设计功能;直升机试飞实验证明,该视景系统取得了比传统视景系统更好的效果。

A scheme to develop a scene simulation system of helicopter is presented. Models commonly used in developing simulation systems and driving technologies （especially Vega Symbology） are researched. The visualized models of helicopter , instruments, and large--area terrain are built based on the modeling software Creator. The DOF technology is employed to coordinate the behaviors of wing rotor, tail rotor and instruments. Finally, the Vega API programming technology under the language environment of C＋＋ is used to implement the scene simulation system of helicopter and the test result of helicopter flight experiment shows it performances better than visual systems built in traditional methods.
