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.
Claims15
A thrust reverser for an engine comprising:
- an air extractor pump 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 pump, the air extractor pump and the air ejector pump defining (a) a first fluid flow path for the portion of the air, the portion of the air to be ejected from a location on an exterior surface of the engine via the first fluid flow path and (b) a second fluid flow path for the portion of the air, the portion of the air to be ejected via the second fluid flow path to a location in the interior portion of the engine different from a location in the interior portion in which the portion of the air was extracted.
An engine comprising:
- a thrust reverser to generate reverse thrust by directing air from an interior volume of the engine to an exterior of the engine;
- first pumping means to extract a portion of the air from the interior volume;
- and
- second pumping means to eject the portion of the air, the first pumping means and the second pumping means defining (a) a first fluid flow path for the portion of the air, the portion of the air to be ejected from the interior volume to a location on an exterior surface of the engine via the first fluid flow path and (b) a second fluid flow path for the portion of the air, the portion of the air to be ejected via the second fluid flow path to a location in the interior volume of the engine different from a location in the interior volume in which the portion of the air was extracted.
