A multiple bypass turbofan engine includes a core Brayton Cycle gas generator with a fuel rich burning combustor and is provided with a variable supercharged bypass duct around the gas generator with a supercharging means in the supercharged bypass duct powered by a turbine not mechanically connected to the gas generator. The engine further includes a low pressure turbine driven forward fan upstream and forward of an aft fan and drivingly connected to a low pressure turbine by a low pressure shaft, the low pressure turbine being aft of and in serial flow...
[ What is claimed is:] [1.] A multiple bypass turbofan engine comprising:a Brayton Cycle gas generator having a fuel rich burning combustor;a fan section comprising in downstream serial flow relationship a forward fan and an aft fan;said fan section upstream and forward of said gas generator and drivingly connected to a low pressure turbine by a low pressure shaft that is aft of and in serial flow communication with said gas generator;a fan bypass duct disposed radially outward of said gas generator and having first and second annular inlets disposed bet...
