Abstract (en)

[origin: EP1207268A1] The cooling process is applied to a gas turbine blade (1). A slot (15) is eroded into the leading edge region of the platform (3), Cooling air (25) from the underside (8) of the platform is shock-cooled as it enters and the top side (7) of the platform is film-cooled. The channels (17) leading into the slots can be laser-drilled, with the slot walls being protected by an anti-adhesion strip.
