A variable cycle turbofan engine (10) includes first and second fans (14,16) independently joined to respective turbines (26,24). A first bypass duct (46) surrounds a core engine disposed in flow communication with the second fan (16). A second bypass duct (48) surrounds the first bypass duct (46) in flow communication with the first fan (14). A first exhaust nozzle (66) is joined to both the core engine and first bypass duct (46). And, a second exhaust nozzle (68) is joined to the second bypass duct (48). |
