Aircraft turbine engine thrust reverser

A thrust reverser system for use with aircraft turbine engines mounted on the fuselage on an aircraft which comprises:

• an engine shroud having four radially spaced openings with forward and aft ends;
• said openings located at about +45 degrees, -45 degrees, +135 degrees and -135 degrees to the vertical;
• plurality of doors having inner and outer surfaces movable between stowed and deployed positions adapted to close each opening when in the stowed position;
• independent actuator means for moving each of said plurality of doors between said stowed position and said deployed position in which each door extends through said aft end of said opening, with the door at least partially blocking air flow through said shroud and further directing airflow exiting said opening in an outwardly and forwardly direction therefrom;
• said doors when fully deployed in aggregate divert from about 50 to 80 percent of the engine flow out through said openings;
• strakes on said doors adjacent to said fuselage for directing reverse air flow in a direction reducing impingement of reverse air flow on said fuselage;
• and
• hinge means mounted said stakes on said doors and further including strake actuator means for folding said strakes when said doors are stowed and for deploying said strakes when said doors are deployed.

A thrust reverser system for use with aircraft turbine engines mounted to an aircraft fuselage which comprises:

• an engine shroud having three radially spaced openings having forward and aft ends;
• the space between two adjacent openings being oriented toward said fuselage;
• said openings being substantially equally spaced around said shroud;
• a plurality of doors having an inner and outer surface, each of said doors having an upstream and a downstream end adapted to close each opening when in a stowed position;
• independent door actuator means for moving each door between said stowed position and a deployed position in which each upstream door end projects outside said shroud and further directs from about 50 to 80% of the airflow exiting said opening in an outwardly and forwardly direction from said shroud;
• at least some of said doors including a strake mounted on the inner door surface, said strake movable between a stowed position lying substantially against the inner door surface and a deployed position extending away from said inner door surface, whereby airflow along said inner door surface is guided in a selected direction.
