Abstract (en)
A blade for an axial-flow turbine comprises a cooling passage (6, 7 , 19, 21) formed inside the blade (1) to direct a cooling medium along and beneath at least one of the suction side surface (4) of the blade (1) and the pressure side surface (3) of the blade (1) such that a core (8) of the blade (1) defined by being jacketed by the cooling passage (6, 7, 19, 21) is thermally isolated towards the blade surface (2,4).
