摘要
提出一种针对飞机机翼积冰模型的建模方法。在分析水滴运动轨迹和积冰成核临界条件的基础上,对结霜和积冰两种条件下积冰增长进行分析。建立霜层内部热量质量传递和表面热量平衡方程,形成关于温度、湿度以及表面温度的积冰厚度和积冰增长模型,并进行飞机地面积冰数值模拟。
A modeling method for aircraft wing icing is proposed. With the analysis of droplet trajectory and icing critical conditions of ice nucleation, growth of icing frosting and icing under two conditions are analyzed. Internal quality frost heat transfer equation and surface heat balance equation are built, meanwhile, the ice thickness and ice growth model about temperature, humidity and surface temperature is conformed and aircraft ground icing simulation is carried out.
