Aircraft fuselage heating

摘要

A method of heating an aircraft fuselage comprises the step of supplying heat energy to air occupying an interior space enclosed by an aircraft fuselage shell structure so as to drive moisture from air in a region disposed immediately adjacent the structure to air in a region disposed from the structure within the enclosed space (20), thereby substantially preventing ice formation on the interior of the structure when the exterior of the structure is exposed to temperatures in the region of -35° C. to -85° C. The heat energy may be supplied by either a heater mat or a heat pipe assembly (16) in an aircraft fuselage.
