Turbine blade and gas turbine with such a turbine blade

摘要

The turbine blade has a blade element (67) arranged along a blade axis (73) and a platform region (61) at the foot of the blade with a platform (71) transverse to the blade axis, whereby the platform has a first wall (70) that does not support the blade and a second wall (69) that does. The first platform wall has an aerodynamic curvature (104) in the transition (65) from the blade to the platform and the second platform wall has a reverse protrusion stage (103) relative to the first wall. An independent claim is also included for a gas turbine with an inventive turbine blade.
