Abstract (en)
The turbine guide blade (22) has first transverse edge (38a) which exhibits curved progression (37) through which platform surface (28) extends in a convex manner whereby first transverse edge progress along pressure level line of hot gas (11), along which an identical pressure of hot gas is obtained. Independent claims are also included for the following: (A) Application of the turbine guide blade; (B) Transition area; (C) Thermal protection shield; and (D) Method for evaluation and production of a turbine guide blade.
