Abstract (en)

[origin: EP1008723A1] The method involves passing coolant fluid along the line between two immediately adjacent platforms (310,310') in a coolant channel (330) extending along both platforms. The coolant channel runs approximately parallel to the platform surface, at least in some sections of its length. Turbine blades (320) are mounted on the platforms and the channel runs between the blades on a path approximating to the blade profile. An Independent claim is also included for the platforms of a turbine machine, esp. a gas turbine.
