  • Patent number: 4451201
    Abstract: A gas turbine comprises a specially fluted rotor that induces a set of co-rotating axial vortices within the average circumferential flow. In an expansion turbine these vortices transfer angular momentum and torque to the fluted rotor. One advantage is a rotational tip speed of the rotor slower than conventional turbines and hence reduced tip stress. In a compressor the rotor imparts kinetic energy to the gas.
