摘要:

为了满足复合材料结构同时具备射频信号透射性能和防除冰性能的要求,提出了将镂空图案化电加热组件做为电热防除冰系统核心部件的方法,针对两种典型的镂空图案化电加热组件分别开展了电热防冰系统防冰性能冰风洞试验。试验结果表明:镂空图案化形状和镂空比是影响残余冰大小、表面温度分布和是否会产生溢流冰的主要因素。在有些试验状态下会在防护区域产生规则的残余冰粒,而且残余冰粒具有周期性脱落的规律。

Abstract:

To satisfy the requirements of composite material structures with both radio frequency signal transmission performance and anti-icing performance, a method is put forward to use the hollowed patterning electric heating module as the core part of the electric heating anti-icing system. Two typical hollowed patterning electric heating modules are tested to evaluate the anti-icing performance in the icing wind tunnel. The results show that the shape of the hollowed patterning and the hollowed ratio are the main factors affecting the size of the residual ice, the surface temperature distribution and the potential for runback ice formation. Under certain test conditions, regular residual ice particles are produced in the protection areas, with the regularity of periodic shedding.

Key words: electric heating anti-icing system, hollow, patterning, anti-icing performance, icing wind tunnel test
