A gas turbine engine comprises a core gas generator engine 16, a power turbine, 30 a fan section 52, and a booster compressor 66. The power turbine 16 includes first and second counterrotatiable turbine blade rows effective for rotating first and second drive shafts, 44, 48 respectively. The fan section includes a first fan blade row 58 connected to the first drive shaft 44 and a second fan blade row 62 connected to the second drive shaft 48. The booster compressor includes a first compressor blade row 70 connected to the first drive shaft 44 and a second compressor blade row 74 connected to the second drive shaft 48. An alternative configuration of compressor blade rows is disclosed (Fig. 2). The power turbine blade rows rotate at substantially the same speed. <IMAGE>
