AERODYNAMIC FEATURE FOR AFT EDGE PORTIONS OF THRUST REVERSER LOWER BIFURCATION WALL

摘要

A thrust reverser of a propulsion system nacelle is provided. The thrust reverser includes a fixed structure, a translating structure, and an aerodynamic feature. The fixed structure includes an annular wall that partially defines an annular bypass airstream duct. The fixed structure is bifurcated into left and right side sections. The annular wall extends between upper and lower bifurcation walls of the left side section, and extends between upper and lower bifurcation walls of the right side section. The translating structure is moveable relative to the fixed structure, between a stowed position and a deployed position. The aerodynamic feature that includes a flange disposed relative to an aft end portion of one of the lower bifurcation walls. The flange aids in preventing aerodynamic drag.

1. A thrust reverser of a propulsion system nacelle, the thrust reverser comprising:
a fixed structure that includes an annular wall that partially defines an annular bypass airstream duct, wherein the fixed structure is bifurcated into left and right side sections, wherein the annular wall extends between upper and lower bifurcation walls of the left side section, and extends between upper and lower bifurcation walls of the right side section; a translating structure that is moveable relative to the fixed structure, between a stowed position and a deployed position; and an aerodynamic feature that includes a flange disposed relative to an aft end portion of one of the lower bifurcation walls, wherein the flange aids in preventing aerodynamic drag.
