本文以流体动力学微下击暴流模型产生三维风场,对飞机穿越风暴着陆进行了模拟。通过对纵横向运动特征的分析,揭示了飞机运动的特征。发现横航向运动难以操纵,对飞行安全威胁很大。一般的经典理论设计出来的横侧向自动着陆系统往往满足不了要求。采用二次指标函数按优化理论求得的操纵规律能够满意地控制航迹偏差最小。
In this paper, a three-dimensional wind field is generated by a hydrodynamic microburst model to simulate the landing of an aircraft across a storm. By analyzing the vertical and horizontal movement characteristics, the characteristics of the aircraft movement are revealed. It was found that it was difficult to maneuver the cross-axis movement and posed a great threat to flight safety. The lateral design of the classic theory of the automatic landing system often can not meet the requirements. The manipulative law obtained by the second-order index function according to the optimization theory can satisfactorily control the minimum deviation of the track.
