Design of Aircraft Wing Defrosting Device

摘要: 飞机穿越含过冷水滴云层时，机翼易结冰，结冰系统引发的积冰会威胁飞行安全。基于机翼结冰原理，本文在分析多种防除冰方法后，确定以热气防冰系统为核心方案。通过传热分析，研究结冰对飞行的影响及马赫数对机翼表面换热系数的作用，明确表面温度防除冰相关化霜装置核心部件的设计原理，为防除冰系统提供技术支撑。

Abstract: When aircraft pass through clouds with supercooled water droplets, wings are prone to icing, and icing caused by the icing system threatens flight safety. Based on the icing principle of aircraft wings, after analyzing various anti-icing and de-icing methods, this paper determines the hot air anti-icing system as the core scheme. Through heat transfer analysis, it studies the impact of icing on flight and the effect of Mach number on wing surface heat transfer coefficient, and clarifies the design principle of core components of defrosting devices related to surface temperature anti-icing and de-icing, providing technical support for the anti-icing and de-icing system.
