Pivot thrust reverser surrounding inner surface of bypass duct

摘要

A pivot thrust reverser includes a first pivot door forming a first portion of a nacelle when stowed and second pivot door forming a second portion of the nacelle when stowed. The first pivot door and second pivot door each form a portion of a surface of a bypass duct when in a stowed position. In the deployed position the first pivot door and the second pivot door circumferentially surround a portion of an inner surface of a bypass duct such that when the pivot thrust reverser is deployed during engine operation a fan bypass stream is redirected while both a core stream and a nacelle ventilation stream flow in substantially the same manner as when the pivot thrust reverser is stowed.

1. A pivot thrust reverser for use in a gas turbine engine assembly, the pivot thrust reverser comprising:
a first pivot door forming a first portion of an outer surface of a nacelle when stowed; a second pivot door spaced from the first pivot door forming a second portion of the outer surface of the nacelle when stowed, wherein the first pivot door and the second pivot door are axially aligned and radially opposite along an axis of the gas turbine engine assembly and each form a portion of a surface of a bypass duct when stowed; an actuator configured to pivot both the first pivot door and the second pivot door from a stowed position to a deployed position; a first linkage on the first pivot door connected to the actuator; and a second linkage on the second pivot door connected to the actuator, wherein in the deployed position the first pivot door and the second pivot door circumferentially surround a portion of an inner surface of a bypass duct such that when the pivot thrust reverser is deployed during engine operation a fan bypass stream is redirected while both a core stream and a nacelle ventilation stream flow in substantially the same manner as when the pivot thrust reverser is stowed.
