Abstract
A gas turbine engine and a turbine stator assembly 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. The stator vane comprises a cooling passage 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 communicated to a radially outward end of the cooling passage. The stator vane further has an adjustment member secured to the stator vane so that it covers the inlet. The adjustment member has two apertures 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.
