摘要:

降水對飛行的影響一直是航空氣象關(guān)注的重點。本文選取2017年6月10日02：30—18：00的一次強降水過程的雨滴譜觀測數(shù)據(jù)，分析了強降水時段雨強與能見度之間的相關(guān)關(guān)系發(fā)現(xiàn)，雨強與能見度呈明顯的負相關(guān)關(guān)系。通過計算平均雨滴譜的各種特征參量，各種粒子對雨強的貢獻情況，在雨強較小的區(qū)間主要為小粒子，而雨強越大，大粒子的貢獻逐漸顯現(xiàn)，在最大雨強的區(qū)間，出現(xiàn)了三峰形態(tài)，3種直徑粒子的高濃度對強降水不同階段的貢獻各不相同，對航班飛行的影響也存在差異。使用雨滴參數(shù)計算了雨滴對飛機撞擊力，分析各類飛機在強降水環(huán)境下的飛行受力均達到了10%的動力狀況；受力方面各機型在低值區(qū)接近一致，有大型機在高值區(qū)迅速增加的情況；同樣的雨強，小型機受到的力要遠小于大型機；各機性在水平方向上的受力情況均較垂直方向大一個量級。

Abstract:

The influence of precipitation on the flight has always been the focus of aviation meteorological attention. In this paper, the data of rain-drop spectrum for a heavy precipitation process from 02:30 BST to 18:00 BST on June 10, 2017, are selected. The correlation between rain intensity and visibility during heavy precipitation was analyzed, and found the negative correlation between rain intensity and visibility. By calculating the various characteristic parameters of the average rain-drop spectrum, the contribution of various particles to the rain intensity is mainly small particles in the area where the rain intensity is small, and the greater the rain intensity.The contribution of large particles gradually appears, and in the maximum rain intensity interval, three peaks have appeared. The contribution of a high concentration of three kinds of diameter particles to different stages of heavy precipitation is different, and the influence on flight is also different. The author calculated the impact force of raindrops on the aircraft using the raindrop parameters, and analyzed that the flight force of all types of aircraft under heavy rainfall environment reached 10% of the dynamic conditions. In the aspect of force, each model is close to the same in the low-value area, and the rapid increase of the mainframes in the high-value area; With the same strong rain, the power of the minicomputer is much smaller than that of the mainframe; The mechanical force in the horizontal direction is one magnitude larger than that in the vertical direction.
