Abstract
In a thermally loaded blade for a turbomachine, the front edge of such a blade is made from a ceramic material for providing better protection. The front edge has a shell-shaped form which covers at least one part of the head stage against which flow occurs. The connection between front edge and head stage is produced on the one side by a coupling-forming indentation and on the other side by an elastic element. The elastic element produces a retaining action at the location where it is placed and a frictional connection, having an effect on the indentation, on the other side of the blade. Cooling air bores in the head stage provide for a cooling effect on the ceramic front edge.
