摘　　要：在基于HLA框架的飞机运动仿真系统中,在SGI图形工作站上创建了三维视景仿真联邦成员,基于pRTI和TCP/IP协议实现了三维视景仿真联邦成员与其他联邦成员之间的信息传递;应用Multigen Creator软件建立了飞机实体模型,在Vega实时仿真驱动平台上实现了飞机起降过程的场景控制与可视化仿真,并设计了多通道的渲染模式和多视角的观察模式,解决了SGI工作站与PC机之间数据通信过程中存在的字节序与存储结构问题,为飞机调度与飞行控制等算法研究提供了形象、直观的科学试验手段。The 3-dimensional visual simulation federation member on the platform of SGI graphics workstation was deeply discussed, which was established on the basis of HLA （High Level Architecture） protocol to simulate the process of taking off and landing for airplane in the airplane simulation system. The interactive class message and the object class message were communicated based on the pRT1 and TCP/1Pprotocol from the other federation members to the 3-dimensional visual simulation federation member. Some object models of airplane were created by using the modeling software Multigen Creator. The real-time simulating software Vega and its supplied functions were introduced to drive the whole scene, and the multi-channel rendering mode and the multi-viewpoint observing mode were designed to support vivid and large scale visual simulating. Furthermore, some problems were solved, such as the byte sequence and the storage structure during the communicating process between SGI graphics workstation and the interface communicating computer. The 3-dimension visual simulation system is an effective and intuitionistic experimental method and is helpful to study the schedule and flight control algorithms for airplane in future.
