Gas Turbine

摘要

The gas turbine comprises a compressor, a combustion chamber (2), a guide vane row (3) and a rotor airfoil row. The guide vane row (3) comprises a plurality of guide vane airfoils comprising a blade (7) and an inner platform (8). The ratio between the pitch (P) and the leading edge diameter (D) of the guide vane airfoils is between 6.3-7.6 and the ratio between the platform length (L) and the leading edge diameter (D) of the guide vane airfoils is between 4.0-5.5.
