基于Vega Prime的运载火箭飞行仿真技术研究

Vega Prime是一个优秀的视景仿真软件,包括LynX Prime GUI(用户图形界面)工具快捷场景配置,并提供了强大的底层图形API接口。本文基于Vega Prime的场景显示框架,通过定制应用实例主循环控制场景显示,以运载火箭飞行仿真为例,探讨了仿真中的几个关键技术,包括飞行位姿更新、动态添加、删除模型节点和粒子系统控制,实现了对运载火箭的飞行、姿态调整和级间分离等不同运动状态的仿真,真实地模拟了运载火箭的飞行过程,为相关教学及其观展提供了良好的场景显示环境。

Research on Flight Simulation Technology of Carrier Rocket based on Vega Prime

Vega Prime is an outstanding scene simulation software,which includes LynX Prime GUI tool for configuring scene rapidly and provides powerful Application Programmer Interfere（API）. Basing on scene simulation framework of Vega Prime, this article controlled scene display by customizing the main frame of the application. Taking flight simulation of car- rier rocket into account, this article discussed several key technologies, including updating flight attitude, adding or deleting model＇s nodes dynamically and controlling particle system. The simulation of some different motion state, such as rocket flighting, attitude adjusting, stage separating and so on was realized, which simulated the flight of carrier rocket truly. And the simulation provided a good display environment for relevant teaching and visiting.
