对称翼型前缘积冰粘结强度试验研究
Experimental Research on Adhesion Strength of Ice Accretion on Leading Edge of Symmetric Airfoil
摘要
Abstract
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.关键词
