Patent ID: 8382431

Claim:
A turbine rotor blade comprising: an airfoil with a leading edge and a trailing edge and a pressure side wall and a suction side wall both extending between the leading edge and the trailing edge; an open cavity formed between the edges and walls; a radial cooling supply channel formed in a leading edge of the airfoil and extending from a root to a blade tip; a row of vortex chambers formed within the pressure side wall and extending from adjacent to the radial cooling supply channel to the trailing edge region; a row of vortex chambers formed within the suction side wall and extending from the trailing edge region to adjacent to the radial cooling supply channel; a plurality of feed slots to connect each of the vortex chambers from the radial cooling supply channel along the pressure side wall and along the suction side wall; a row of trailing edge exit slots connected to the vortex chamber located nearest to the trailing edge; and, a row of suction side wall diffusion slots connected to the last vortex chamber on the suction side wall in the series to discharge cooling air.
