ABSTRACT:
A gas turbine cooling blade maintains a cooling effect and prevents sticking of deposits to the belly surface of the blade. The blade is provided with a relatively big cooling hole formed on the belly part of a hollow stator blade at an acute angle with the blade surface for blowing out cooling air. A relatively small cooling hole is disposed downstream of the big hole at a more acute angle with the blade surface to bring a jet of cooling air along the blade surface.
