摘要
对民用飞机在跑道上滑行时的轮迹横向偏移规律进行研究。采用自主研发的高频非接触轮迹测试系统,依托上海虹桥国际机场西跑道,分两阶段采集4 015组民用飞机在起飞滑跑情形下的轮迹偏移数据。采用数理统计方法,详细分析虹桥机场西跑道的轮迹横向偏移规律与特点。数据分析表明:轮迹横向偏移具有整体偏左的特点;夜间的助航灯光会使飞机整体偏移更靠近跑道中心线。柯尔莫哥洛夫-斯摩洛夫检验结果表明,虹桥机场西跑道的轮迹横向偏移并不严格服从正态分布,而更符合负偏态分布,其总体数据的均值等于-0.34 m,标准差为0.925 m。
A research work about wheel track deviation of civil aircrafts running on runway is presented. A non-contact system with high-frequency measurement of aircraft gear position is independently developed and used. 4 015 groups of aircraft wheel path data in total are measured in two periods of time on the west runway of Shanghai Hongqiao International Airport while all those aircrafts are in the state of taking off. The characteristics of wheel track deviation on the west runway are analyzed via mathematical statistics tools. Results show that the whole deviation of aircrafts is a little left to the centerline of runway. Airfield lighting can lead wheel track path to be more close to the centerline of runway. Results of Kolmogorov-Smirnov test indicate that the deviation of most civil aircrafts＇ wheel track obeys negative skewness distribution rather than normal distribution, and on west runway of Shanghai Hongqiao International Airport the mean value of whole civil aircrafts deviation data is -0.34 m and it＇s standard deviation is 0.84 m.
