Title:
シュラウド冷却セグメント及び組立体
Document Type and Number:
Japanese Patent JP4737879
Kind Code:
B2
Abstract:
A cooling shroud segment (422) for a high pressure turbine that provides improved cooling in the region of the side panels (450) from the midsection (485) thereof forward to the leading edge (446) and particularly in the midsection (485) of the side panel (450). A shroud subassembly (500) can be formed from a pair of such adjacent shroud segments (422) with opposed adjacent side panels (450) where the spacing of the outlets (488, 489) of the cooling air passages (480) exiting from each of these adjacent side panels (450) are staggered and where the adjacent panels (450) have a spline seal slot (492) with a humped section (498) in at least the midsection (485) of the side panel (450) above and across the outlets (488, 489) of the cooling air passages (480) exiting from the midsection (485) of the side panel (450), in combination with a spline seal (492) positioned in the gap (502) between the opposed adjacent side panels (450). This shroud subassembly (500) provides more uniform impingement cooling coverage and localizes more of the cooling air exiting the outlets (488, 489) from these passages (480) in the midsection (485) of the opposed side panels (450).
