초록

An aircraft turbofan engine and method of operation effect variable specific thrust. The engine includes a fan disposed in a fan casing and a booster compressor disposed in a first flow splitter and powered by a core engine. A second flow splitter is disposed inside the fan casing and defines fan outer and inner ducts. The booster compressor includes at least one stage of rotor blades each having a shroud and an integral rotor flade extending radially outwardly therefrom into the fan inner duct. The fan outer duct includes a variable area first exhaust n...
