| 摘 要： | 为在飞行模拟器中高逼真度地模拟在扰动风场中的飞行,研究了大型飞机在起飞着陆阶段遭遇微下击暴流风切变的实时仿真。基于涡环和Rankine复合涡原理建立了参数化三维微下击暴流模型。通过涡环倾斜和多涡环叠加方法实现了各种复杂微下击暴流风场的模拟。基于Boeing747-100飞机建模数据,系统推导了含风切变影响的六自由度动力学模型,给出了扰动风下气动模型修正的一般方法。对该机遭遇微下击暴流时实施纵向和横侧改出分别进行了控制器设计与仿真。研究结果表明,建立的三维微下击暴流模型可扩展性强,可用于模拟实际复杂风场。含风切变影响的大型飞机动力学模型合理有效。针对飞机从不同位置穿越风场,可采用不同的改出策略。整个模型可应用于飞行模拟器的实时飞行仿真。

| Abstract: | This article deals with real-time hi-fi simulation of large aircraft flying in turbulent wind in a simulator to study its takeoff and landing behavior in microburst wind shear.A parameterized three-dimensional(3D) microburst model is built up on the basis of vortex ring and Rankine vortex principle.Complicated microburst wind fields are simulated by means of vortex ring declination and multi-vortex superposition.Based on the modeling data of Boeing 747-100,a dynamic model with wind shear effects considered ... |
