ABSTRACT:
A gas turbine engine includes a turbomachinery core operable to generating a flow of pressurized combustion gases; a rotating fan adapted to extract energy from the core and generate a first flow of pressurized air; a fan stator assembly connected in flow communication with the fan and operable to vary the first flow of pressurized air while the fan operates at a substantially constant speed; a fan outer duct surrounding the core; and a flade stage comprising a supplementary fan disposed in the fan outer duct and driven by the fan for generating a pressurized bleed air flow.
