Patent ID: 8128344

Claim:
A turbine cooling component comprising: a circumferential leading edge; a circumferential trailing edge spaced from the leading edge; a first side panel connected to the leading and trailing edges; a second side panel connected to the leading and trailing edges, spaced and opposed to the first side panel; an arcuate base connected to the trailing ledge and the leading edge having a fore portion, a midsection portion, an aft portion, an opposed first side portion and second side portion, an outer surface partially defining a cavity operative to receive pressurized air, and an arcuate inner surface in contact with a gas flow path of a turbine engine moving in the direction from the leading edge to the trailing edge of the turbine component; a first side cooling air passage in the base extending along the first side portion from the fore portion to the aft portion, wherein the first side cooling air passage has an inner surface including a ridge operative to effect a flow of the pressurized air; and a fore cooling air passage in the fore portion of the base communicative with the side cooling air passage and the cavity, operative to receive the pressurized air from the cavity.
