摘　　要：翼面结冰是威胁飞行安全的重要因素之一。以数值模拟结冰为基础,进行了翼型结冰的工程修正方面的研究。运用结冰分析软件Sadrice,对不同状态下的不同翼型进行表面冰形数值模拟。结合结冰风洞试验结果,对影响冰形的参数进行了变参研究,得到了最有效的修正方法。对现有对流换热系数经验公式进行线性修正,使修正对流换热系数经验公式后的预测冰形和冰风洞试验结果之间能够较好地吻合,最终总结出了一套工程修正数值模拟冰形的方法。The icing of wing is an important factor of threats to flight＇s safety. Based on the numerical simulation of ice, this paper investigates airfoil icing engineering correction methods. Using icing analysis software Sadrice, the numerical simulation of different airfoils surface icing at the various states is done. According to the results of icing wind tunnel test, the change parameters are studied, which affect the ice shape, and the most effective meth- od of correction is obtained. Linearly, The current convective thermal parameter empirical formula is corrected, which fits the numerical shape well. A set of engineering methods to correct the numerical simulated ice shape is summarized in the end.
