Patent ID: 8201390

Claim:
A thrust reverser for a jet engine, said thrust reverser comprising: a translating wall section moveable between a first position and a second position, said translating wall section being adjacent a fixed portion of said jet engine when in said first position, at least a portion of said translating wall section being separated from said fixed portion of said jet engine by a space when said translating wall section is in said second position thereby creating an aperture between said fixed portion of said jet engine and said translating wall section, wherein the aperture is bounded by a forward edge defined by said fixed portion and an aft edge defined by said translating wall section; and a fluid flow reverser element having a forward edge and an aft edge fixed relative to the translating wall section and configured for directing a fluid flow in a direction generally forward relative to said jet engine when said translating wall section is in said second position, said fluid flow reverser element extending only partially into a fluid stream passing through said aperture such that a first portion of fluid of said fluid stream engages said fluid flow reverser element and a second portion of fluid of said fluid stream does not engage the fluid flow reverser element and is entrained within the first portion of the fluid stream, wherein a first distance between said forward edge and said aft edge of said fluid flow reverser element is less than a second distance between said forward edge and said aft edge of said aperture.
