飞行模拟系统中分布交互式视景的设计与实现

Design and Realization of Distributed Interactive Scene with Flight Simulation System

分布交互式视景是飞行模拟系统中的重要组成部分,是实现多机单通道(多通道)联网编队飞行的基础。提出了一种基于Mantis的分布交互式视景仿真系统,对视景系统的视景数据库、视景控制程序及网络结构进行了总体设计,构建了一个具有基本仿真功能,并且相对通用的分布式可视化实时视景仿真系统。并对多通道视景的同步、模拟器之间的时空一致性和三维模型简化等关键技术进行了研究与实现。该系统已经应用于实践,实现了直升机模拟器之间在同一环境下的联网飞行,并且取得了预期的视觉效果。

The distributed interactive scene is an important component of Helicopters simulation system,which can realize formation flying of mutli-helicopters single channel （multi-channnels） by networking.A distributed interactive simulation platform based on Mantis is proposed.Database,control program and network frame of the scene system are designed.The paper has constructed a relatively genera distributional visible real-time scene simulation platform with basic simulation function.And studies the technique in synchronization of multi-channels scene,space-time consistency of the simulator and 3D simplification.The system has been used in the practice,and reaches the expected results.
