An auxiliary fan is disposed upon the periphery of at least a portion of the fan of a conventional gas turbofan engine. Flow modulating components such as variable vanes and nozzles are utilized in conjunction therewith to produce a wide range of operating bypass ratios. Such an engine is one of the variable cycle variety and has the capability of operating efficiently at both subsonic and supersonic speeds.


A variable cycle gas turbofan engine comprising: a core engine including a compressor, a combustor and a core turbine; a stage or rotatable fan blades for pressurizing a motive fluid, a first portion of which enters said core engine and is discharged therefrom in a hot gas stream, and a second portion of which passes as a bypass stream through a first substantially annular duct generally surrounding said core engine; auxiliary compression means comprising a radial extension of said fan blades for pressurizing an auxiliary motive fluid stream; means for m...
