Technical Summary:
The present invention is a deicing system that uses electromagnetic actuators mounted within the airfoil of an aircraft to effect deicing. Advantageously, the actuators have low voltage and current requirements. Each actuator includes conductive strips fabricated on a flexible dielectric sheet. The conductive strips are wound into coils with the actuator shaped into a flattened elongated tube. The axis of the winding coils is coincident with the longitudinal axis of the elongated tube.
