Abstract
A fluid cooled guide vane is disclosed for use in a gas turbine engine which defines a plurality of separate cooling circuits to guide a cooling fluid through the interior of the vane, while at the same time minimizing the pressure drop of the cooling fluid as it passes through the vane. Each cooling circuit has a cooling fluid inlet, a cooling fluid outlet, a cavity and a chamber which is in fluid communication with the cavity and either the fluid cooling inlet, or the fluid cooling outlet. The multiple chambers are located in mounting bases attached at either end of the vane. The mounting bases define the several chambers as well as the cooling fluid inlets. The cooling fluid outlets may either be defined by the mounting bases, or may be formed by rows of orifices through the vane wall in communication with the cavities within the vane.
