Coolant channels close to surface ensure efficient heat transfer. Advanced convection-cooled airfoil consists essentially of metal cover on grooved support structure. Grooves form coolant passages oriented in any direction. After cover material is applied, filler material removed from coolant passages form conduit for heat transfer fluid.
