| 摘要 |
There is described a turbine blade, with a platform and with an aerodynamically profiled blade leaf which extends transversely thereto and which comprises a suction-side blade leaf wall and a pressure-side blade leaf wall which extend from an inflow-side leading edge to an outflow-side trailing edge, with respect to a hot gas flowable along the platform or the blade leaf walls during operation, the platform and/or one of the two blade leaf walls having at least two adjacent regions. To prolong the service life of the turbine blade by equalizing the thermal stresses arising there during operation, the two regions have different heat transfer coefficients on the hot-gas side.
