Abstract:
1. A method for assembling a gas turbine engine, said method comprising: providing a core engine including an inner fan duct for channeling airflow through a portion of the core engine, and at least one inner fan section including at least one row of inner fan blades positioned in the inner fan duct; providing a flade system including a flade duct surrounding the core engine and defining a flade stream, at least one fladed fan positioned in the flade duct and producing a flade stream airflow, wherein the fladed fan includes at least one row of fladed fan blades radially outward of and coupled to the inner fan section such that the fladed fan blades are driven by the inner fan section, and a flade stream augmentor positioned within the flade duct; channeling airflow through the core engine to produce engine thrust; channeling airflow through the flade duct to produce engine thrust; igniting a portion of the airflow channeled through the flade duct using the flade stream augmentor to increase the amount of thrust produced by the flade system.
