The passae has an inlet formed through the inner panel of the thrust reverser door and an outlet, directs a portion of the gas flowing through a cold flow air duct in a forward direction. The gas flowing in the forward direction inpinges upon gases flowing through a laterally facing opening in the housing in order to provide a forward component to this gas flow. A moveable flap may be attached to the thrust reverser door in order to cover the inlet to the passageway when the device is operated in the forward thrust mode.
