降雨对飞机性能影响的计算分析

Calculations of rain effects on aircraft performance

计算了在五种不同降雨率条件下飞行时飞机表面增加的雨水重量以及雨水施加给飞机的水平冲力和垂向冲力,分析了降雨对飞机阻力增量的影响和升力损失特性,研究了风切变条件下的降雨对飞机性能的影响。最后得出了降雨对飞机性能影响的几点结论。

The impacts of rainfall on the aircraft were introduced and the characteristics of raindrops were investigated.The weight of rainfall on the surface of aircraft,and the horizontal and vertical impact forces of raindrops on the aircraft were calculated in the conditions of five different rainfall rates.The impacts on the flight drag and the degradation characteristics of the lift were also analyzed in depth.The effects on the aircraft performance due to rainfall in the wind shear environment were further studied.A summary and some significative conclusions are presented at the end of this paper.
