1. A method of deicing a wind turbine blade, the method comprising:
- applying an active plasma actuator to a desired portion of the wind turbine blade; and
electrically energizing the plasma actuator to ionize the air in the vicinity of the plasma actuator such that the surface temperature of the wind turbine blade in the vicinity of the plasma actuator is increased sufficiently to reduce or eliminate the collection of ice on the desired portion of the wind turbine blade.

Abstract
A system for deicing a wind turbine blade includes an electrically powered active plasma actuator applied to a desired portion of a wind turbine blade. The activated plasma actuator energizes the air in the vicinity of the plasma actuator to increase the surface temperature of the wind turbine blade in the vicinity of the plasma actuator sufficiently to reduce or eliminate the collection of ice on a desired portion of the wind turbine blade.
