Abstract:
1. A thrust reverser assembly for a turbofan engine assembly, the engine assembly including a core gas turbine engine, a core cowl which circumscribes the core gas turbine engine, a nacelle positioned radially outward from the core cowl, a fan nozzle duct having an area defined between the core cowl and a portion of the nacelle, and a thrust reverser positioned within a portion of the nacelle, said thrust reverser assembly comprising: a first cowl; a second cowl repositionable with respect to said first cowl for varying the area of said fan nozzle duct; an actuator assembly positioned within a portion of said nacelle and is configured to couple said second cowl such that said actuator assembly is configured to reposition said second cowl between a first operational position, a second operational position, and a third operational position wherein said second cowl is positioned substantially flush with said first cowl in said first operational position, said first operational position facilitates maximum engine efficiency with maximum thrust; and at least one flow directing member coupled to said second cowl to selectively impede airflow from flowing through a cavity defined between said first cowl and said second cowl.
