超疏水/电热协同防/除冰策略在冰风洞中的实验研究
Experimental Investigation of Super-hydrophobic/Electro-thermal Synergistically Anti-icing/De-icing Strategy in Ice Wind Tunnel
摘要
Abstract
The icing of unmanned aerial vehicles(UAVs)poses a serious threat to flight safety.The available energy of UAVs is inadequate,so an energy-efficient ice protection strategy is required.In this paper,an integral fiberglass composite airfoil is tested,which has super-hydrophobic coating and embedded electro-thermal film(SHS-EET).The proportional integral derivative method(PID)is used to adjust surface temperature and heating power.Experiments are conducted in an icing wind tunnel to verify the anti-icing/de-icing performance of the strategy.The results show that the super-hydrophobic coating without a heating source fails to avoid the formation of accreted ice.In addition,the ice shedding period of SHS-EET is reduced by 64.6%and the energy consumption is reduced by 72.3%.As the surface temperature is lower than 10℃,SHS-EET achieves dry anti-icing.And it reduces energy consumption by 27.5%compared with the wet anti-icing strategy of a fiberglass airfoil with underground electro-thermal film(FG-UET).The hybrid anti-icing/de-icing strategy is beneficial for the development of the icing protection system for UAVs.关键词
