1.以面向对象方法为基础,提出了一种飞行仿真模型的软件框架设计方案;
2.阐述了飞行仿真动力学系统数学模型的建模方法,包括飞行动力学模型、发动机模型等模型的建立方法;
3.对飞行仿真系统使用的以太网进行了网络性能的研究;
4.对飞行的各个阶段进行了仿真,结果表明仿真系统能够反映飞机的真实飞行特性;
5.模型作为核心计算模型参与含硬件回路的实时仿真,建立了飞行模拟器的初步框架。
飞行仿真模型是飞行仿真系统的核心。本文建立了基于面向对象技术的、跨平台、粒度可调的飞行实时仿真模型,并将模型用于实际的飞行模拟器,与视景系统、六自由度运动平台系统、教员台系统等飞行模拟器子系统共同实现了飞行实时仿真系统的基本框架。
This article mainly discusses a software frame of flight dynamic simulation which is based object-oriented design methodology. Some algorithmic methods used on solving the flight dynamic deferential equations and net performance of real-time distributed interactive system were analyzed. The work is carried out as following aspects.
1. The theory and design method of the flight dynamic simulation which is based object-oriented design methodology technology is analyzed. The mathematical character of the simulator model was introduced, including dynamic equations, aerodynamic analysis, engine model, standard atmosphere model, etc.
2. Mathematic method of the flight dynamic simulation is discussed, include flight dynamics model,motor model, act.
3. Net performance of real-time distributed interactive system and the solution of net problems are discussed.
4. The whole flight progress was simulated in real time with fixed step. The result of simulation shows that the model can reflect the flight character of the airplane modeled.
5. The model contains the hardware return route as the core computation model participation the real-time simulation, has established the flight simulator preliminary frame.
The flight dynamic simulation system has a great value in flight simulator. Building software frame which is based object-oriented technology, multi-platform, model size adjustable is mentioned in this paper. The model used in actual flight simulator interactive with display system, 6-DOF motion platform and tutor, completed the initial flight simulator framework.
