摘要：A nacelle assembly for a turbofan engine includes a forward nacelle portionhaving an aft edge and defining a bypass duct that transports bypass airflow of theturbofan engine, a translatable sleeve that is translatable aft of the forward nacelleportion and a reverse thrust apparatus that is movable between a stowed position, and a

deployed position. When the reverse thrust apparatus is deployed, the translatablesleeve is moved aft to a position away from the aft edge of the forward nacelle potion toexpose a cascade assembly comprising an opening in the bypass duct, and one or moreblocker doors are deployed so as to extend into the bypass duct, such that at least aportion of the airflow in the bypass duct is directed out the bypass duct through thecascade assembly. Also, during deployment of the reverse thrust apparatus, at least aportion of the cascade assembly translates toward the engine centerline. The cascadeassembly may have a cross-section that is non-uniform.
