摘要

The gas turbine blade has a platform (8) at the base with an end face (9) which is turned towards the gas flow. A smaller blade (14) whose surface is parallel to the end face is mounted under the platform and is at least as wide as the projection (b) of the blade width on the front edge of the platform.
