Abstract: An ice protection system and method of implementing ice protection for a vehicle includes a plurality of segmented sub-areas each including a leading edge surface subject to the formation of ice thereon. The system further includes a plurality of air ducts, each in fluid communication with at least one of the segmented sub-areas and a source of heated air. A cyclic diverter valve is configured to provide a cyclic flow of heated air via the plurality of air ducts to each of the plurality of segmented sub-areas to protect the leading edge surface from the formation of ice.

Abstract: A hybrid electrical ice protection system implements three ice protection methods in various combinations. The ice protection methods include the fully-evaporative anti-ice protection method, the wet running anti-ice protection method, and the de-ice method. The particular methods that are implemented vary, depending on the particular aircraft structure for which ice protection is being provided and on the power condition of the aircraft.
