ABSTRACT:
An outlet section for a turbofan gas turbine engine (10) includes an internal flow separator (24), and a small convoluted mixer (28) for initiating mixing between the coaxial fan air stream (22) and hot core engine exhaust gas (26). Mixing is enhanced by an increasing-decreasing diameter nozzle plug (38), having a maximum diameter (40) proximate the annular outlet opening (16). The downstream edge (42) of the outer engine fairing (14) is turned radially inward for enhancing forward thrust in cooperation with the decreasing diameter surface (18) of the plug (38).
