Abstract
A thrust reverser for a turbofan engine having an air duct defined radially inwardly by a cowl around a gas turbine and radially outwardly in part by a fan case of the engine includes a bulkhead that is adapted to be mounted on the fan case. A translating sleeve is supported for movement axially between a closed position adjacent the bulkhead and an open position spaced apart axially to the rear of the bulkhead so as to form a outlet opening for discharge of air from the air duct. A cascade array 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.
