摘要
风切变严重威胁处于起飞、着陆阶段飞机的飞行安全。面向在校飞行学员,提出并开发了风切变特情飞行仿真实验。建立含扰动风影响的飞行动力学模型。针对微下击暴流风切变,分析纵向和横侧改出飞行操作。在此基础上,开发一种基于B-S架构的在线虚拟仿真实验平台,实现风切变影响机理分析、基础飞行操作、改出操作和飞行技术考核评价功能。该平台能够帮助飞行学员在理论学习阶段系统掌握风切变飞行原理,树立遵章守纪意识,培养特情处置能力。
Wind shear makes aircraft face deadly dangers during takeoff and landing. Aiming at flight cadets, a flight simulation experiment for wind shear special flight was first put forward and developed. Firstly, a flight dynamics model with wind effects was built up. Secondly, the longitudinal and lateral flight control strategies were analyzed for microburst wind shear escape. On this foundation, an online virtual platform for wind shear special flight was developed based on Browser-Server(B-S) structure. The mechanism analysis of wind shear effects, basic flight control, escaping control and flight technology evaluation were realized on this platform. The platform can help the flight cadets understand the flight principle in wind shear. Furthermore, the consciousness of obeying flight rules and disciplines can be established, and the disposal capacity in special flight will be strengthened.
