摘要

结冰翼型气动影响分析是飞机结冰问题重要的研究内容之一，可帮助进行飞机结冰安全分析和容冰设计。为填补现阶段关于冰形表面粗糙度对翼型气动影响的研究空缺，以冰形的粗糙度参数（冰形表面粗糙高度和冰形表面粗糙分散度）为依据，提出了一种冰形粗糙度叠加方法；并通过有限体积法求解空间离散的RANS方程，结合S-A湍流模型，分别针对流线冰型和角状冰型，量化分析了不同微观特征参数的冰形对翼型失速特性的影响规律，为研究飞机结冰问题提供了思路和基础。结果表明，对于流线结冰翼型，冰形表面粗糙度会明显影响翼型的失速性能；而对于角状结冰翼型，两个凸起的羊角状外形才是导致气动力损失的主要因素，粗糙度的影响往往可不考虑在内。

Abstract

The aerodynamic impact of ice accretion is one of the most important research contents in aircraft icing problems. However

to the authors' knowledge

related studies on the effect of ice roughness on airfoil aerodynamic characteristics are still quite rare. Therefore

the present paper proposes an ice roughness superposition method based on ice roughness parameters (surface roughness height and surface roughness dispersion). The Reynolds averaged Navier-Stokes equations are solved by the finite volume method with the S-A turbulence model. The influence of ice accretion with different ice roughness parameters on airfoil aerodynamic characteristics

especially on the airfoil stall characteristics

is analyzed for both rime ice and glaze ice

which will hopefully provides some enlightenment for aircraft icing problems. Results show that

the roughness parameters of the rime ice will result in a significant effect on airfoil stall performance. However

for a glaze iced airfoil

the two horn-like protrusions are the main factors causing the aerodynamic loss

while the effect of ice roughness parameters is negligible.
