ABSTRACT:
A turbine stator vane structure is described which comprises an airfoil having a pressure side and a suction side and at least one duct of preselected size defined through the airfoil from the pressure side to the suction side thereof with preselected orientation with respect to the camberline of the airfoil for directing a predetermined portion of the turbine engine gas flow through the airfoil whereby the gas flow angle and momentum at the rotor inlet plane of the engine is selectively altered. A rotatable slotted sleeve may be included within each duct for selectively throttling flow therethrough.
