Abstract (en)
Air- and steam-cooled turbine blade (1), especially a gas turbine blade, with an edge (10) comprises a blade wall, at least one steam chamber (16, 17) for steam cooling, and at least one air chamber (18) for air cooling. The steam chamber and the air chamber are separated from each other. The edge is at least partly cooled with air. <??>Independent claims are also included for an alternative air- and steam-cooled turbine blade, and for processes for cooling the above turbine blades. Preferred Features: The steam chamber is completely surrounded by the blade wall.
Abstract (de)
Die Erfindung betrifft eine Gasturbinenschaufel (1), die in getrennten Hohlräumen (16,17,18) sowohl mit Luft als auch mit Dampf gekühlt wird. Insbesondere die Anstreifkante (10) wird luftgekühlt, wobei die Anstreifkante (10) aerodynamisch günstig dünn ausführbar ist. Der größte Teil der Gasturbinenschaufel (1) wird verdichterluftsparend dampfgekühlt. <IMAGE>
