Abstract (en)
A turbine blade/vane comprising a blade/vane airfoil (40, 42) mounted on a base platform (18, 20) and extending along an elongation axis, said base platform (18, 20) in a first basal direction extending between an upstream surface (46, 48) and a downstream surface (50, 52) is provided that due to its design contributes to minimizing the negative and undesired effects of the leakage flows in the turbine section. For this purpose, in said upstream surface (46, 48) a cavity (60, 62) extending along a second basal direction approximately perpendicular to said elongation axis is provided.
