First Claim
Patent Images
1. A thrust reverser for an engine comprising:
- an air extractor to extract a portion of air from an interior portion of the engine, the air in the interior portion of the engine to generate reverse thrust with respect to a direction of travel of the engine; and
an air ejector to eject the portion of the air from a location on an exterior surface of the engine.

Abstract
Thrust reversers and methods to provide reverse thrust are disclosed. An example thrust reverser includes a cascade to direct air from an interior volume of an engine nacelle to generate reverse thrust with respect to a direction of travel, and an air extractor to extract a portion of air approaching the cascade from within the interior volume.

18. A method comprising:
-
coupling a cascade of a thrust reverser to an engine of an aircraft, the cascade to direct air from a nacelle of the engine to generate reverse thrust relative to a direction of travel of the aircraft; coupling an air ejector to the engine; and forming an air ejection location on an exterior surface of the engine, the air ejection location to be formed forward of the cascade relative to the direction of travel of the aircraft, the air ejector to eject air via the air ejection location. - View Dependent Claims (19, 20)
