【摘要】：对民机在进近着陆阶段可能诱发飞行事故的低能量状态和驾驶员的改出操纵方法进行了研究。根据近年的民机事故分析报告,结合运输类飞机适航标准CCAR-25-R4、飞行试验指南AC25-7C、军用规范及相关行业标准,较系统地提出了涉及着陆拉平、侧风着陆和可控撞地的低能量状态的定量判定准则。以某型支线客机为例,采用数字仿真计算的方法,分别研究了在进近着陆过程中低动能和低势能状态可能导致的飞行安全问题及其特点。针对低动能改出提出了增加速度并抑制爬升的方法,针对低势能改出提出了增大俯仰姿态并保持速度的方法,最后通过仿真计算验证了两种改出方法的有效性。研究结果可为低能量告警系统的设计和驾驶员的改出操纵培训等提供理论参考。
[Abstract]:In this paper, the low energy state of civil aircraft which may induce flight accident in the approaching landing stage and the method of pilot's operation are studied. According to the analysis report of civil aircraft accidents in recent years, combined with the airworthiness standard CCAR-25-R4 for transport aircraft, the flight test guide AC25-7C, the military code and related industry standards, the paper systematically puts forward the related landing leveling. Quantitative criteria for low energy state of cross wind landing and controllable impact. Taking a regional airliner as an example, the problems and characteristics of flight safety caused by low kinetic energy and low potential energy during approach landing are studied by means of digital simulation. A method of increasing speed and restraining climbing is proposed for low kinetic energy output, and a method for increasing pitch attitude and keeping velocity is proposed for low potential energy conversion. Finally, the effectiveness of the two methods is verified by simulation. The results can provide a theoretical reference for the design of low energy alarm system and the training of driver.
