摘　　要：当飞机在寒冷潮湿的环境中飞行时,机翼前缘有时会出现结冰现象威胁飞行安全。为了发展防冰和除冰技术,有必要对叶片翼型表面覆冰的粘结特性进行研究。本文设计并搭建了叶片翼型覆冰粘结力测量系统,提出了叶片翼型覆冰粘结强度的评估方法,记录和测量了不同条件下NACA0018翼型叶片段上的结冰分布和粘结强度。试验结果表明,结冰时间对冰粘结强度的影响较小。随着环境温度降低,叶片翼型表面冰粘结强度增加,但增长速率减小。此外,随着风速增加,叶片翼型表面冰粘结强度降低。本研究结果为深入探索叶片翼型覆冰粘结机理提供了参考。When aircraft operate in a cold and humid environment,ice accretion occurs on the leading edge of wing at times,which threatens the flight safety.For developing anti-icing and de-icing technologies,it is necessary to explore the adhesive characteristic of ice covering on the blade airfoil surface.In this paper,a measurement system of ice adhesion for blade airfoil is designed and built.And an evaluation method of ice adhesion strength for the blade airfoil is proposed.The distribution and adhesion strength of ice on the blade segment with airfoil of NACA0018 are recorded and measured under different conditions.The experiment results show that icing time is less significant to the ice adhesion strength.As the ambient temperature decreases,the adhesion strength of ice on the blade airfoil surface increases,but the growth rate decreases.In addition,when the wind speed increases,the adhesion strength of ice on the blade airfoil surface decreases.The research findings provide a reference for deeply exploring the adhesion mechanism of ice covering on blade airfoil.
