用于热隔离涡轮转子轮的系统、方法及设备
摘要：
本发明的实施例可提供用于热隔离涡轮转子轮(105)的系统、方法及设备。根据一个实施例，可提供一种用于热隔离涡轮转子轮(105)的方法。涡轮转子轮可包括支承相应的涡轮转子叶片(110)的一对叶片支柱(125)或柄部，使得柄部腔(145)形成在相应的叶片支柱(125)之间。为了热隔离涡轮转子轮(105)，可提供可操作成用以将柄部腔(145)分隔成上部区域(345)和下部区域(355)的至少一个密封件(350)。此外，该密封件(350)可放入柄部腔(145)内，以便将柄部腔分隔成上部区域和下部区域。在此情况下，冷却空气流可在上部区域与下部区域之间分开，使得下部区域相比于上部区域可保持在更低温度。
摘要（英）：

Embodiments of the invention can provide systems, methods, and an apparatus for thermally isolating a turbine rotor wheel (105). According to one embodiment, a method (700) for thermally isolating a turbine rotor wheel (105) can be provided. The turbine rotor wheel can include a pair of blade posts (125), or shanks, supporting respective turbine rotor blades (110) such that a shank cavity (145) is formed between respective blade posts (125). To thermally isolate the turbine rotor wheel (105), at least one seal (350) operable to partition the shank cavity (145) into an upper region (345) and alower region (355) can be provided (705). In addition, this seal (350) can be inserted (710) within the shank cavity (145) to partition the shank cavity (145) into an upper region (345) and a lower region (355). In doing so, cooling air flow can be divided between the upper region (345) and the lower region (355) so that the lower region (355) can be maintained at a lower temperature than the upper region (345).
