Abstract:
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 anti-icing， 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.
