Abstract (en)
[origin: EP1138878A2] The panel-shaped projecting component has a surface charged by hot gas, and bores for a coolant. At least one plenum chamber (30) is located next to the surface (2) charged by the hot gas, and the coolant passes through it in a convective flow. The coolant bores are formed as blow-out aperture, which extend from the plenum chamber and open into the hot gas-charged surface, thereby generating a coolant film. Plenum chambers and/or blow-out apertures are formed by an EDM process.
