Abstract
A stator of a turbine of a gas turbine, having a flow duct in which stator vanes are arranged, each vane having an outer and an inner vane platform, and each having a cooling air chamber formed by adjacent vane platforms for passing through cooling air, characterized in that the resultant cooling air chamber and/or a platform intermediate gap are designed such that starting from a side of the vane platform facing the adjacent vane platform, at least one outflow pocket open to a platform upper side and connected to the cooling air chamber is formed, and that in the wall of the cooling air chamber, at least one cooling air pocket opened radially inwards to the cooling air chamber and limited by an intermediate element or a sealing strip is formed and opens to the platform intermediate gap.
