Abstract:

Aircraft icing threatens flight safety. To solve this problem, this paper makes a comparative study of the anti-icing performance of plasma actuation, resistance wire electric heating and graphene electric heating arranged on the NACA0012 airfoil in the icing wind tunnel by recording the icing dynamics process and the temperature variation of the area. The results show that with the same input power, both plasma actuation and graphene electric heating can effectively prevent icing, while resistance wire electric heating cannot completely prevent ice accumulation in the area without heat source. The infrared measurement results show that the maximum surface temperature of graphene electrothermal film after heating is lower than that of the other two methods. However, due to its uniform heating properties, the minimum temperature of the entire heated surface remains above 0 ℃, which is sufficient to prevent icing. For plasma actuation and resistance wire electric heating, the temperature distributions on their surfaces are not uniform. The heat dissipation performance of plasma actuation is higher than that of resistance wire electric heating. Plasma actuation directly heats the incoming cold air and supercooled water droplets around the actuator by gas discharge near the wall, while resistance wire electric heating has poor heat conduction in the insulating medium and thus cannot effectively increase the surrounding heat, resulting in icing easily in the area without heat source.
