Methods and apparatus for operating gas turbine engines.

摘要

A method for operating an aircraft engine facilitates preventing ice accumulation on the aircraft engine. The method comprises coupling a semi-permeable membrane (66) to the engine adjacent an outer surface (68) of the engine, coupling a fluid reservoir (62) to the aircraft engine in flow communication with the semi-permeable membrane, and supplying fluid from the fluid reservoir to the semi-permeable membrane to facilitate preventing ice accumulation on the aircraft engine outer surface.
