摘    要:舰载机进近速度过大不仅会缩短机体疲劳寿命,而且会增加事故风险。通过分析得出,造成进近速度超出预期值的原因是飞行员为保证飞机沿固定下滑道下滑而对飞机的状态作出了调整。进一步分析得出,甲板风高于测试值是迫使飞机状态改变的直接因素,并利用统计数据分析验证了该结论的正确性;分析结果表明,甲板风增大的80%转化为进近速度的增加;提出以抬高基准角的方式应对大甲板风带来的进近速度的增加,以保证着舰安全。研究结论可应用于岸基模拟着舰训练中,可提高模拟训练和实际着舰的相似度,增强训练效果。


Research on the influencing factors of the carrier-based aircraft exceeding the anticipated landing approach speed
Abstract:Higher approach speed could not only shorten the aircraft fatigue life,but also increase the risk of accident.It is concluded through the analysis that the reason of speed exceeding the expected one is that the pilot must maintain his aircraft on glideslope to adjust the parameters within his control.Further theoretical analysis shows that wind over deck higher than that in the test is the direct cause;the statistical date analysis verify the correcmess of the conclusions;the results show that 80% of the increase of wind over decks is tumed into the increase of approach speed.It is proposed to raise the reference angle to cope with the increase of approach speed so as to ensure the landing safety.The conclusion can be applied to the field carrier landing practice to improve the simulation training and the actual landing similarity,which can enhance the training effect.
