AIAA Aviation 13-17 June 2016, Washington, D.C. 47th AIAA Plasmadynamics and Lasers Conference Experimental Study of Deicing and Anti-icing on a Cylinder by DBD Plasma Actuation Xuanshi Meng∗, Jinsheng Cai†, Yongqiang Tian‡, Xuzhao Han§, Duo Zhang¶, Haiyang Hu∥ Northwestern Polytechnical University, Xi’an 710072, China Icing has been recognized as a potentially dangerous phenomenon on aircraft and re- mains a difficult problem to solve. The current paper conducts an experimental study to investigate a novel approach for icing control that employs a DBD plasma actuator at- tached on a cylinder model surface subject to a supercooled flow in wind tunnel. The effects of plasma actuation on deicing and anti-icing are studied by surface temperature measurements in quiescent air and icing wind tunnel. Firstly, the influence of the electrical parameters on the surface temperature of the actuator is measured by infrared thermal camera in quiescent air circumference. Secondly, surface temperatures of the actuator during de- and anti-icing period are measured on a cylinder model in icing wind tunnel. Thirdly, the power consumption is calculated and discussed. Finally, the conclusion is drawn.

Introduction In-flight icing is widely recognized as a significant hazard to aircraft safety in cold weather. It adversely affects the performance of an aircraft by inducing roughness and even modifying shape of the exposed surface due to the accumulated ice. Indeed, the aerodynamic performance of an aircraft flying in icing conditions can degrade very rapidly and, consequently quickly lead to incidents and accidents.1 When an aircraft or rotorcraft flies in a cold climate, some of the supercooled droplets would impinge and freeze on the exposed aircraft surfaces to form ice shapes. Ice may accumulate on every exposed frontal surface of an airplane, not only on the wing, propeller and windshield, but also on the antennas, vents, intakes, and cowlings. Icing accumulation can degrade the aerodynamic performance of an airplane significantly by decreasing lift while increasing drag. In moderate to severe conditions, an airplane could become so iced up that continued flight is impossible. The airplane may stall at much higher speeds and lower angles of attack than normal. It could roll or pitch uncontrollably, and recovery may be impossible. Ice can also cause engine AIAA 2016-4019 ∗Associate professor, Department of Fluid Mechanics. †Professor, Department of Fluid Mechanics. ‡Graduate Student, Department of Fluid Mechanics §Graduate Student, Department of Fluid Mechanics ¶Graduate Student, Department of Fluid Mechanics ∥Graduate Student, Department of Fluid Mechanics 1 of 14 Copyright © 2016 by the American Institute of Aeronautics and Astronautics, Inc.
