Aircraft flying in cold environments have a high risk of icing on their airfoils. The ice accumulation can not only decrease the flight efficiency, but also, in extreme cases, cause flight accidents. Therefore, effective anti/de-icing method is urgently needed to improve flight safety under icing conditions. Plasma-based anti/de-icing method is a novel method with the advantages of high-efficiency and fast heating, which can be mainly divided into Dielectric Barrier Discharge (DBD) anti-icing method and plasma synthetic jet (PSJ) anti-icing method. This two methods are combined in this paper and the de-icing performance of the composite method is tested in icing wind tunnel tests. Firstly, studies the de-icing processes of DBD and the PSJ are investigated independently. Then, the performance of the composite method is validated. Results show that the de-icing performance of the independent application of DBD and PSJ is not good, while the composite plasma deicing method works well. The ice in the de-icing region can be completely removed by the composite method. At the same time, the plasma composite deicing can greatly reduce the energy consumption and shorten the deicing time, compared with the independent usage. The main mechanism of this enhanced performance is that, the DBD can melt the inner ice sheet, making the adhesion force between the ice sheet and the airfoil decrease. When the rods of the PSJ actuator hit the ice sheet, the melted ice can be continuously striped from the airfoil due to the decreased adhesion, which causes the ice to break violently and finally blow away with the incoming stream. These results can help solve the problem of aircraft de-icing.
