What is it about?
The plasma actuation is feasible and effective for the in-flight anti-icing, and it has the potential to meet the icing control needs of next-generation aircraft. Three types of actuators have been designed to generate induced flows in different directions. The results in an icing wind tunnel show that the anti-icing performance is directly related to the design of the plasma actuators based on the coupled aerodynamic and thermal effects.

Why is it important?
We found that the performance of plasma icing control is directly related to the design of the plasma actuators based on the coupled aerodynamic and thermal effects. The criterion for plasma actuator optimization for icing control is that the actuator can generate as much heat as possible locally, and at the same time, it should be easily carried by the induced flow and better mixed with the incoming flow.
Perspectives
Over the past year, we have been working to explore the mechanism explanation of plasma icing control through experimental research. This article is a summary of that work. We found that the performance of plasma icing control is directly related to the design of the plasma actuators based on the coupled aerodynamic and thermal effects. Such novel findings provide an important basis for system optimization of plasma icing control. This is the greatest innovation of this manuscript.
