ROTATABLE SCARF INLET FOR AN AIRCRAFT ENGINE AND METHOD OF USING THE SAME

摘要

A rotatable scarf inlet for an engine and a method of operating a jet aircraft engine on an aircraft. The rotatable scarf inlet is rotatably supported at a forward end portion of a nacelle of the engine. The rotatable scarf inlet is controllably rotatable relative to the engine nacelle to a plurality of angular positions to inhibit ingestion of foreign object debris or to improve airflow characteristics, depending on whether the aircraft is taxiing, taking off from a runway, or operating in a cruise condition. The method involves controllably rotating the rotatable scarf inlet with respect to the engine nacelle to a corresponding one of the plurality of angular positions.
