Abstract
A thrust reverser for a turbofan-type turbojet engine assembly is disclosed having a deflector defining an upstream edge of a reverse thrust opening formed in the turbofan housing so as to control the direction and shape of the gases passing through the reverse thrust opening. The deflector has a deflector edge portion defining a deflector edge wherein the curvature of the deflector edge portion, as measured in a longitudinal radial plane passing radially through a longitudinal axis of the engine, varies in a direction from one side of the reverse thrust opening to the opposite side of the opening. The curvature of the deflector edge portion is defined as being positive when the center of curvature of the deflector edge portion lies radially outwardly of the deflector and is defined as being negative when the center of curvature of the deflector edge portion lies radially inwardly of the deflector. The deflector edge portion may have a positive curvature adjacent to one side of the reverse thrust opening and a negative curvature adjacent to an opposite side of the reverse thrust opening such that the deflector edge defines a continuous smooth curve from one side of the reverse thru…
