Cascade-type thrust reverser

摘要

A thrust reverser for a turbofan engine having an air duct defined radially inwardly by a cowl (10) around a gas turbine and radially outwardly in part by a fan case (12) of the engine includes a bulkhead (22) that is adapted to be mounted on the fan case (12). A translating sleeve (18) is supported for movement axially between a closed position adjacent the bulkhead (22) and an open position spaced apart axially to the rear of the bulkhead (22) so as to form a outlet opening for discharge of air from the air duct. A cascade array (40) fixed in the outlet opening has a substantially conical portion, the forward end of which is of a diameter substantially smaller than the diameter of the rearward end. <IMAGE>
