Abstract

The power turbine includes a first rotor 38 having a plurality of first turbine blade rows extending radially outwardly therefrom, and a second rotor 48 having a plurality of second turbine blade rows extending radially inwardly therefrom. The power turbine is supported aft of the gas generator and is effective for receiving combustion gases therefrom and expanding the gases through the first and second turbine blade rows for extracting substantially all output power therefrom for driving the first and second rotors in counterrotating directions for driving counterrotating fans or propellers disposed either at a forward end or at an aft end of the engine. <IMAGE>
