Patent ID: 8720182

Claim:
A variable area fan nozzle for use with a gas turbine engine system, comprising: a nozzle having a cross-sectional area associated with a bypass air flow flowing in an aft direction through a fan bypass passage, the nozzle having at least one section that is selectively moveable between a plurality of positions for varying the cross-sectional area and at least one thrust reverse position, which is different from the plurality of positions, for reversing a direction of the bypass air flow from the fan bypass passage, and wherein the at least one section of the nozzle includes an inner wall bounding an outer diameter of the fan bypass passage and an outer wall outwards of the inner wall with respect to the fan bypass passage, with an open auxiliary passage extending between the inner wall and the outer wall, the open auxiliary passage extending between the inner and outer walls from an upstream forward opening to a downstream aft opening that opens in the aft direction to an exterior of the nozzle, the downstream aft opening located upstream of a trailing edge of the inner wall.
