大气环境仿真中数据模型及数据库的设计与实现

大气环境对飞行器有着至关重要的影响,不仅影响着飞行器本身的飞行和作战性能,而且也影响着飞行器操纵人员的决策.所以,大气环境仿真是高逼真度飞行仿真器设计的一个的重要组成部分.该文基于数据场的概念建立了大气环境数据模型,然后根据这个大气环境数据模型设计了一个具有四叉树结构的大气环境数据库,很好地解决了多分辨率的问题.最后将大气环境数据库映射到SEDRIS表示.

Design and Implementation of the Data Model and Database in Simulation of Atmosphere

Atmosphere has critical impacts on the aircraft,it will not only impact the performance of flight and fight of the aircraft,but also the decision of the pilot.So simulation of atmosphere is an important part of the design of high fidelity flight simulator.In this paper,a data model is created based on the concept of data field,and then an atmosphere database with quad-tree structure is designed according to this data model.It solves the problem of multi-resolution very well.Finally,the database is represented in SEDRIS.
