【摘要】：對民機在進近著陸階段可能誘發(fā)飛行事故的低能量狀態(tài)和駕駛員的改出操縱方法進行了研究。根據(jù)近年的民機事故分析報告,結(jié)合運輸類飛機適航標準CCAR-25-R4、飛行試驗指南AC25-7C、軍用規(guī)范及相關(guān)行業(yè)標準,較系統(tǒng)地提出了涉及著陸拉平、側(cè)風著陸和可控撞地的低能量狀態(tài)的定量判定準則。以某型支線客機為例,采用數(shù)字仿真計算的方法,分別研究了在進近著陸過程中低動能和低勢能狀態(tài)可能導致的飛行安全問題及其特點。針對低動能改出提出了增加速度并抑制爬升的方法,針對低勢能改出提出了增大俯仰姿態(tài)并保持速度的方法,最后通過仿真計算驗證了兩種改出方法的有效性。研究結(jié)果可為低能量告警系統(tǒng)的設(shè)計和駕駛員的改出操縱培訓等提供理論參考。
[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.
