Abstract
A turbofan exhaust nozzle includes: a conical inner shell disposed coaxially inside a surrounding outer shell to define an annular flow duct therebetween terminating in an outlet at a trailing edge of the outer shell and the inner shell terminates in a trailing edge aft of the outlet; and a pylon interrupting circumferentially the duct, wherein at least a portion of the trailing edge of the outer shell is vertically non-coplanar.
Claims14
A turbofan exhaust nozzle comprising:
- a conical inner shell disposed coaxially inside a surrounding outer shell to define an annular flow duct therebetween terminating in an outlet at a trailing edge of the outer shell, the conical inner shell terminating in a trailing edge aft of the outlet, wherein the conical inner shell diverges aft inside the annular flow duct to a hump and then converges aft to the trailing edge aft of the outlet thereof, and an axial position of the hump vanes circumferentially therearound corresponding to an axial position of the trailing edge of the outer shell;
- and
- a pylon interrupting circumferentially the annular flow duct, wherein at least a portion of the trailing edge of the outer shell is vertically non-coplanar.
