PIVOTING BLOCKER DOOR FOR THRUST REVERSER

摘要

A thrust reverser includes a translating sleeve and a blocking door assembly that includes two, three, or four blocker door segments. The translating sleeve is movable axially with respect to a fan case and a core cowl between a cruise position and a thrust reversal position. The blocker door segments are positioned adjacent an inner wall of the translating sleeve in the cruise position, and are pivotable to a position in which the blocker door segments substantially block the bypass duct in the thrust reversal position. Each blocker door segment is connected to the translating sleeve at transverse ends by a pair of support bearings that establish a pivot axis along an arc chord of the blocker door segment.

主权项

1. A thrust reverser comprising:
a translating sleeve that is axially movable between a forward cruise position and a rearward thrust reversal position; and a set of two, three, or four blocker door segments pivotally mounted to the translating sleeve, the blocker door segments being positioned adjacent an inner wall of the translating sleeve when the translating sleeve is in the cruise position, and being pivotable to a position in which the blocker door segments substantially block bypass airflow when the translating sleeve is in the thrust reversal position, wherein each blocker door segment is pivotally connected to the translating sleeve at transverse ends by support bearings that establish a pivot axis along an arc chord of the blocker door segment.
