摘要
基于翼型结冰特性,研究了直升机旋翼桨叶结冰后的空气动力学特性,分析了桨叶不同剖面位置结冰类型、结冰厚度、沿不同方位角的升力特性变化,初步分析了空气动力作用对桨叶结冰增长的抑制作用,为国内直升机结冰试飞提供理论参考。
Based on the characteristics of airfoil icing, established the helicopter rotor blade icing aerodynamic characteristics. Then analyzed the different blade profile location ice type, ice thickness, lift characteristics changed along the different azimuth. Preliminary analyzed the effect of aerodynamic on the ice growth inhibition at different positions of the blade. It will provide theoretical reference for domestic helicopter icing flight test.
