摘要：

过冷大水滴（SLD，supercooled large droplet）结冰会在机翼上方形成冰脊，严重影响飞机的飞行安全。为了探究

冰脊对带舵面翼型的气动和操纵特性的影响规律，本文采用计算流体力学（CFD，computational fluid dynamics）

数值计算方法，在不同的冰脊高度下对带舵面翼型进行数值模拟研究。仿真结果表明：冰脊会造成翼型的升力

系数减小、阻力系数增大和舵面操纵效率大幅降低；本算例中，在攻角 α = 4° 下冰脊高度 k/c = 0.013 9 出现上翼

面的气流完全分离，舵面操纵效率损失超过 40%，翼型的气动和操纵特性大幅下降。

Abstract:

The formation of ice ridges above the wing by icing of supercooled large droplet (SLD) can seriously affect the

aircraft flight safety. In order to investigate the effects of ice ridges on the aerodynamic and control characteristics

of ruddered airfoils, numerical simulations were carried out using computational fluid dynamics (CFD) for ruddered airfoils under different ice ridge heights. Simulation results show that ice ridges cause a reduction in the lift

coefficient, an increase in the drag coefficient and a significant reduction in the rudder control efficiency of the

airfoil; in this example, the airflow over the upper surface of the airfoil is completely separated at an ice ridge

height of k/c = 0.013 9 at angle of attack α = 4°, resulting in a rudder control efficiency loss of over 40% and a significant degradation of the airfoil′s aerodynamic and control characteristics.

Key words:

supercooled large droplet (SLD) icing, ice ridges, aerodynamic characteristics, rudder control efficiency
