Zusammenfassung:	To provide a turbine shroud including cooling passages in communication with collection plenums.SOLUTION: Turbine shrouds for turbine systems are disclosed. The turbine shrouds may include a forward end, an aft end, a first and second side, an outer surface facing a cooling chamber formed between the body and the turbine casing, and an inner surface facing a hot gas flow path for the turbine system. The turbine shrouds may also include at least one collection plenum extending within the body between the forward end and the aft end. Additionally, the turbine shrouds may include a set of cooling passages extending within the body. Each of the cooling passages of the set may include an inlet portion in fluid communication with the cooling chamber, an outlet portion in fluid communication with the at least one collection plenum, and an intermediate portion fluidly coupling the inlet portion and the outlet portion.SELECTED DRAWING: Figure 3 【課題】収集プレナムと連通する冷却通路を含むタービンシュラウドを提供する。【解決手段】タービンシステム用のタービンシュラウドが開示される。タービンシュラウドは、前端部、後端部、第１および第２の側面、本体とタービンケーシングとの間に形成された冷却チャンバに面する外面、および前記タービンシステムの高温ガス流路に面する内面を含んでもよい。タービンシュラウドはまた、前端部と後端部との間で本体内に延在する少なくとも１つの収集プレナムを含んでもよい。さらに、タービンシュラウドは、本体内に延在する一組の冷却通路を含んでもよい。一組の冷却通路の各々は、冷却チャンバと流体連通する入口部分、少なくとも１つの収集プレナムと流体連通する出口部分、および入口部分と出口部分とを流体結合する中間部分を含んでもよい。【選択図】図３
