Abstract

Aircraft icing seriously jeopardizes flight safety. The design of aircraft anti-icing/de-icing systems requires a thorough understanding of the adhesion between the ice and the substrate. In this research, an experimental device that can be housed within a wing is designed and constructed. Simulation analysis of the interfacial stresses is performed, which reveals that increasing the load and the interface size led to a deterioration in the uniformity of stresses at the interface. In addition, the ice layer does not undergo cohesive damage during the tests. The normal ice adhesion strength is evaluated in an icing wind tunnel using the methodology outlined in this paper. Glaze ice exhibits an increase in normal adhesion strength at lower temperatures, whereas the trend is reversed for rime ice. The minimum adhesion strength occurs near the medium volume diameter (MVD) of 30 µm. Furthermore, the normal strength is significantly enhanced by increase in wind speed and surface roughness, as well as by surface painting. The adhesion strength of aluminum substrates to ice is greater compared to titanium and stainless steel. Compared to shear adhesion strength, normal adhesion strength is less sensitive to various influencing factors. The proposed experimental framework provides precise measurement of normal adhesion strength of impact ice in the icing wind tunnel.

结冰风洞中正常冰附着强度的研究

飞机结冰严重危害飞行安全。飞机防冰/除冰系统的设计需要彻底了解冰与基材之间的粘附性。在本研究中，设计并制作了一种可装在机翼内的实验装置。对界面应力进行了仿真分析，结果表明，载荷的增大和界面尺寸的增大会导致界面应力均匀性的恶化。此外，在试验过程中，冰层没有发生粘性损伤。利用本文提出的方法，对结冰风洞中正常冰的粘附强度进行了评估。釉冰在较低温度下表现出正常粘附强度的增加，而对于霜冰则相反。最小粘附强度出现在中等体积直径(MVD) 30µm附近。此外，风速和表面粗糙度的增加以及表面涂漆显著增强了正常强度。与钛和不锈钢相比，铝基材对冰的粘附强度更大。与剪切粘接强度相比，正常粘接强度对各种影响因素的敏感性较低。所提出的实验框架提供了结冰风洞中冲击冰法向黏附强度的精确测量。
