Abstract
A thrust reverser is disclosed having a thrust reverser door with an outer door panel pivotally attached to an inner door panel which, in turn, is pivotally attached to an annular housing. The door panels are pivotable about parallel, but displaced pivot axes such that the inner door panel undergoes a greater range of motion between its closed and open positions that does the outer door panel. This enables the inner door panel to be flush with the upstream and downstream portions of the inner housing surface to provide a smooth airflow through the air duct during the forward thrust mode, while at the same time enabling an efficient operation of the door during the reverse thrust mode.
