Hybrid electrical ice protection system and method including an energy saving mode

摘要

A hybrid electrical ice protection system including at least a first set of heaters (208-1) and a secon set of heaters (208-2) 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.
