地面飞行模拟器的训练效果主要取决于动力学建模的逼真度和满足正常/特殊情况飞行任务的程度。首先,分析了影响飞机动力学特性和飞行员操作各个因素的相互关系,旨在从任务飞行、故障飞行和特殊环境条件飞行三方面拓展地面飞行模拟器的模拟能力;其次,进行了飞机空中编队、方向舵故障、雨中飞行以及非线性起落架减振支柱的仿真。研究结果表明,拓展地面飞行模拟器的应用范围是实际飞行的需要且技术可行,关注细节的部件建模更是提高地面飞行模拟器逼真度和可信度的关键。
The training effect of ground flight simulator mainly depends on the fidelity of dynamic modeling and the degree of satisfying the normal / special situation missions. First of all, the paper analyzes the interrelationship between the factors that affect the dynamics of aircraft and the pilots’ operation. The aim is to expand the simulation capability of ground flight simulator from three aspects: mission flight, flight failure and special environmental conditions. Secondly, Rudder failure, flight in the rain, and nonlinear landing gear vibration damping strut simulation. The results show that expanding the application scope of ground flight simulator is the need of actual flight and the technology is feasible. The component modeling focusing on details is the key to improve the fidelity and reliability of ground flight simulator.
