Abstract text

A device for feeding combustion air to an engine disposed in an interior of an aircraft is comprised of an 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 one further air inlet duct extending between a second region of the exterior surface and the engine, so as to provide a two-way airstream supply; and a control device configured to switch the air supply to the engine to the at least one further air inlet duct when a blockage occurs in the air inlets.
