GAS TURBINE AND TURBINE STATIONARY BLADE FOR SAME

摘要

A gas turbine engine a turbine stator assembly 1 which is capable of being cooled effectively with a small amount of air. The stator assembly comprises a stator vane disposed to be exposed to a combustion gas passage 18. The stator vane comprises a cooling passage 24 defined therein. The cooling passage is disposed on an upstream of the gas turbine engine and extending in a radial direction with respect to a central axis of the gas turbine engine. The stator vane also has an inlet 28 communicated to a radially outward end of the cooling passage. The stator vane further has an adjustment member 29 secured to the stator vane so that it covers the inlet. The adjustment member has two apertures 30a, 30b for guiding a cooling air radially inwardly through the inlet into the cooling passage. The two apertures are spaced away from each other along a camber line of the stator vane.
