  • 摘要:

    基于民机的适航要求,建立了一种基于数字虚拟飞行的侧风着陆地面航向操稳特性评估方法。以着陆滑跑过程中最大机体倾斜角和最大航迹偏移量作为评估的关键参数,依据人机闭环数字飞行仿真计算结果,评估了某大型水陆两栖飞机侧风着陆任务的地面航向操稳特性适航符合性。对于20 kts侧风分量,算例飞机着陆滑跑的机身最大机体倾斜角为3.44°,最大侧向航迹偏差为2.51 m,能够满足适航要求。进一步研究表明,侧风分量大小、道面污染情况均影响侧风着陆的安全性。在干道面上当侧风分量超过30 kts时即会出现地面打转现象;道面污染增加滑跑减速所消耗的跑道长度,同时不利于驾驶员对滑行航向的控制。所提评估方法可应用于民机的概念和方案设计阶段,并为后续开展飞行试验验证等提供理论参考。
