Abstract

A thrust reverser for a jet engine comprises a translating wall section moveable between a stowed position and a deployed position. The translating wall section is adjacent an annular fan duct wall or other fixed portion of the jet engine when in the stowed position and is separated from the annular fan duct wall when in the deployed position, thereby creating an aperture through which a fluid stream passes. A fluid flow reverser element directs the fluid stream in a direction generally forward relative to the jet engine when the translating wall section is in the deployed position. The fluid flow reverser element extends only partially into the fluid stream such that only a first portion of fluid of the fluid stream engages the fluid flow reverser element. A second portion of the fluid stream is entrained in the first portion and is thereby directed forward relative to the jet engine.
