ABSTRACT:
A blade cooling construction comprising a cylindrical hollow and a nozzle, both of which are defined in and by the blade. The hollow and nozzle create a vortex of cooling gas introduced into the blade, which gas whirls about the axis of the hollow by tangentially injecting the cooling gas into the hollow through the nozzle. A portion of the cooling gas is lowered in temperature, and the other portion is raised in temperature. The lower temperature cooling gas is introduced first to a central portion of the blade height which is higher in temperature than the remaining portions of the blade. The higher temperature cooling gas is introduced to a lower temperature portion of the blade.
