US Classification:
416/190000
Abstract:
A compressor blade includes an airfoil portion having a leading edge, a radially inner attachment portion, and a platform between the airfoil portion and the attachment portion, wherein material is removed from the attachment portion to form an undercut at a front face thereof to thereby provide an overhang radially inward of the platform and leading edge of the airfoil portion, the undercut defined by a narrow entry slot opening into a rearward transverse groove.

Abstract:
A method of controlling wheelspace temperature in a gas turbine comprising: (a) extracting air from a compressor used to supply compressed air to the gas turbine for combustion; (b) supplying air extracted in step (a) to the wheelspaces in the gas turbine; and (c) controlling flow of air supplied in step (b) to achieve a desired wheelspace temperature.
