An aircraft propulsion system includes a gas turbine engine having a fan
section, at least one row of FLADE fan blades disposed radially outwardly
of and drivingly connected to the fan section, the row of FLADE fan
blades radially extending across a FLADE duct circumscribing the fan
section, an engine inlet including a fan inlet to the fan section and an
annular FLADE inlet to the FLADE duct. A fixed geometry inlet duct is in
direct flow communication with the engine inlet. The fan section may
include only a single direction of rotation fan or alternatively axially
spaced apart first and second counter-rotatable fans in which the FLADE
fan blades are drivingly connected to one of the first and second
counter-rotatable fans. The row of FLADE fan blades may be disposed
between rows of variable first and second FLADE vanes.
