【摘要】：為了簡化機場滑行區(qū)彎道增補面設(shè)計方法,依據(jù)飛機滑行時起落架輪胎的轉(zhuǎn)彎輪跡,建立相應(yīng)的微分方程,并將飛機滑行軌跡分為鼻輪在圓曲線上行駛和鼻輪駛?cè)胫本�2段進(jìn)行求解,得到了增補面內(nèi)緣線的解析解;引入相對縱距、位置系數(shù)和表征轉(zhuǎn)彎道面增補面加寬量的增補寬度系數(shù),分析了轉(zhuǎn)彎道面增補面特征,基于不同彎道轉(zhuǎn)角與相對縱距下增補寬度系數(shù)的相似性,給出了圓曲線上增補寬度系數(shù)的回歸方程與直線段開始時飛機縱軸與駛出直線初始夾角的修正式;結(jié)合圓曲線上增補面內(nèi)緣線的微分方程解提出了機場轉(zhuǎn)彎滑行道增補面設(shè)計新方法,并與ICAO方法進(jìn)行了對比。計算結(jié)果表明:當(dāng)彎道轉(zhuǎn)角為135°,半徑為45m,飛機最大軸距為25m,主起落架寬度為13m時,采用新方法計算的最大增補面加寬量為7.52m,采用ICAO方法計算的最大增補面加寬量為7.53m,兩者差別小于0.2%;采用新方法只需確定彎道的分界點,便可計算出彎道增補面內(nèi)緣線任一點的坐標(biāo),但是采用ICAO方法必須求出整個增補面內(nèi)緣線后才能確定某一增補面內(nèi)緣點的坐標(biāo),因此,新方法不僅計算結(jié)果滿足精度和安全性要求,而且計算過程簡單,使用方便。
[Abstract]:In order to simplify the design method of the additional curved plane in the taxiway area of the airport, the differential equation is established according to the turning wheel track of the landing gear tire when the aircraft is taxiing. The aircraft glide trajectory is divided into two sections: the nose wheel travels on the circle curve and the nose wheel moves into the straight line, and the analytical solution of the inner edge line of the supplementary plane is obtained. The relative longitudinal distance, the position coefficient and the additional width coefficient are introduced to analyze the characteristics of the additional surface of the turning road surface, based on the similarity of the supplementary width coefficient between the different corner angles and the relative longitudinal distance. The regression equation of the additional width coefficient on the circular curve and the correction of the initial angle between the longitudinal axis of the aircraft and the outgoing line at the beginning of the straight line are given. Combined with the differential equation solution of the inner edge line of the added plane on the circular curve, a new method for the design of the additional plane of the taxiway in the turn of the airport is proposed and compared with the ICAO method. The calculation results show that when the turning angle of the bend is 135 擄. When the radius is 45m, the maximum wheelbase of the aircraft is 25m and the width of the main landing gear is 13m, the maximum additional surface width calculated by the new method is 7.52m. The maximum addition surface width calculated by ICAO method is 7.53m.The difference between the two is less than 0.2m. By using the new method, the coordinates of any point of the inner edge of the additional surface of the bend can be calculated by simply determining the dividing point of the bend. However, the ICAO method must be used to find out the inner edge line of the supplement surface before the coordinates of the inner edge point of a supplementary surface can be determined. Therefore, the new method not only meets the accuracy and security requirements of the new method. Moreover, the calculation process is simple and easy to use.
