- 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 (FGUET). The hybrid anti-icing /de-icing strategy is beneficial for the development of the icing protection system for UAVs.
