摘要
主要介绍了模型的研究领域和定义，并以飞行模拟器飞行系统数学模型为例，说明了实际－理论模型－计算机模型的建立过程，以及飞行系统的建模、编程、数据的选取及预处理等对飞行模拟器逼真度的影响。概述了飞行系统（包括本地管理程序、初始化程序、多功能各异、相对独立的应用于程序以及所需的数据文件）与其它系统的关系。提出了计算欧拉积分法的各种方法，包括矩形积分、梯形积分和加权型的梯形积分。还讨论了飞行仿真模型的通用数学模型和校验方法。
This paper introduces the simulation space and the definition of 'models', and a process of establishing the reality-conceptual model-computer moudel via an example of computer programming of a flight system model for flight simutors,and influence of modelling, programming, selecting data on fidelity for a flight simulator. it describes relationships between the flight system (including local management programs, initialization programs,,various-function relativety-independent application routines and the required data documents ) and other systems. The trapezoid integration,rectangle integration and weighted trapezoid integration can be used to calculate the Euler integration for the equations of motion of a aircraft. It also discusses how to establish common mathematical models and verifying methods for flight simulation models.
