Abstract (en)
[origin: EP1048822A2] At the heat shield for a gas turbine, cooling drillings (27,28) are in both longitudinal sides of the heat shield segments. Cooling air passes through the drillings from the hollow space between the paired arms (21-24) into the radial gap (29,30) betwe the longitudinal sides of the heat shield segments (17) and the neighboring outer (14) and intermediate (15) rings, to prevent t entry of hot gases from the hot gas channel (11) entering the gaps (29,30).
