Abstract (en)

[origin: EP1746254A2] A cooling arrangement in a turbine section of gas turbine engines is used to direct cooling air within shroud segment platforms (44) for cooling the turbine shroud (32) while forming substantially straight cooling air streams for impingement cooling on a turbine vane outer shroud (38).
