Abstract
A ceramic core used to cast and cooling circuit in a thin wall turbine airfoil, where the ceramic core includes a row of metering and impingement forming pieces that discharge into a radial plenum, followed by a row of pedestals and a row of diffusion channels that then flow into a single discharge slot. The ceramic core has bumpers of both sides to position the core in a wax mold. The metering and impingement holes are offset from the cooling passage in the airfoil wall so that impingement of the hot surface of the wall occurs.
