Claim:
1. A gas turbine apparatus comprising: a first driving shaft; a second driving shaft; a compressor configured to receive power from the first and second driving shafts, suck air, and compress the sucked air at high pressure; a combustor configured to mix the compressed air with fuel, and combust the fuel mixture to generate combustion gas; and a turbine connected to the first and second driving shafts and configured to rotate while the combustion gas passes through the turbine, the turbine comprising one or more first turbine blades configured to rotate in a first direction and one or more second turbine blades configured to rotate in a second direction opposite to the first direction, the one or more first turbine blades and the one or more second turbine blades being alternately arranged along an axial direction of the turbine, the first driving shaft connected to each of the first turbine blades and the second driving shaft connected to each of the second turbine blades, the first turbine blade including a first blade part having a rear end, the second turbine blade including a second blade part having a front end, and a distance from a central-axis line of the first driving shaft to the rear end of the first blade part is substantially equal to a distance from the central-axis line of the first driving shaft to the front end of the second blade part.
