Abstract

A device for feeding combustion air to an engine disposed in an interior of an aircraft is comprised of a primary air inlet duct extending between an exterior surface of the aircraft and the engine, wherein the air inlet duct extends from air inlets disposed in a first region of the exterior surface; at least two further air inlet ducts extending between a second and third region of the exterior surface and the engine, so as to provide a three-way combustion air supply; and a control device configured to switch the air supply to the engine from either or both of the at least two further air inlets duct when a blockage occurs in the primary air inlet.
