摘　　要：为防止溢流冰的生成,在降低能耗的同时实现干态防冰的效果,发展了一种低能耗干态防冰技术。在基于传热原理的防冰设计基础上引入促进水脱落的思想,使撞击在表面的过冷水维持在液态并保持较低的表面温度。利用超疏水表面促进水脱落作为主要防护手段,增大水脱落量的同时减小换热时间,能够降低液态水在防冰表面的溢流,减少表面换热能耗,抑制了溢流冰的生成,实现了良好的防冰效果。结冰风洞试验结果表明,与传统的热防护方法相比,低能耗干态防冰技术能够显著抑制前缘结冰和溢流冰生成,并降低防冰能耗。In order to prevent the formation of runback ice and achieve dry anti-icing effect while reducing energy consumption,a low⁃energy consumption dry anti-icing technology is developed.Based on the principle of thermal antiicing,the idea of water shedding is introduced to keep the impact water liquid at a lower surface temperature.Superhydrophobic materials are used to promote water shedding as the main protection method to increase water shedding and reduce heat exchange time.The runback of liquid water on the surface and the energy consumption of surface heat exchange are reduced.The formation of runback ice is suppressed to achieve anti-ice effect and reduce energy consumption.The test results show that the low⁃energy dry anti-icing technology can significantly inhibit the formation of leading edge ice and runback ice,and reduce the required power compared with traditional thermal protection methods.
