Abstract
In a gas turbine power plant including at least three turbine rotors operating upon independent shafts, one rotor is designed to drive the compressor, one is designed to produce the main part of the power output and the third rotor is adapted to aid the two first mentioned rotors, variable transmission means being provided to interconnect the rotor shafts. In order to improve part load efficiency this third rotor is provided with vanes being substantially slim and straight when compared with the conventional reaction type blades of a power turbine, whereby this third rotor may act as a power producing turbine during high loads, and as a power consuming fan during part and low loads.
