Abstract
The present invention provides a movable air deflector which, in a first position, deflects air passing through the cold flow air duct of a turbofan engine in a direction such that it approximates the theoretical air flow line and does not enter a cavity defined by the interior of the thrust reverser door when the door is in its closed position. A linkage mechanism connects the air deflector to the door actuator, such that, when the door is moved to its opened or thrust reversing position, the deflector is moved to a second position so as to minimize its interference with the thrust reversing air flow.
