Abstract
An axial flow gas turbine () has a rotor with alternating rows of air-cooled blades () and rotor heat shields, and a stator with alternating rows of air-cooled vanes () and stator heat shields () mounted on inner rings (A) reduction in cooling air mass flow and an improved cooling and effective thermal protection of critical parts within the turbine stages of the turbine is achieved by adapting the stator heat shields () and outer vane platforms () within a turbine stage (TS) to one another such that air () leaking through the joints between the outer vane platforms () and the adjacent stator heat shields () into the hot gas path () is directed onto the blade crown () of the blades ().
