초록

A gas turbine engine having a core gas generator engine for generating combustion gases, with an additional power turbine, an additional fan section, and a booster compressor. The power turbine includes two counter rotatable turbine blade rows which are alternately interdigitized and serve to rotate counter rotating first and second drive shafts, respectively. The fan section also includes counter rotating spaced apart fan blade sections which are respectively connected to the first and second drive shafts. A booster compressor is axially positioned betw...
