摘要:
Embodiments of a gas turbine engine cooling system (100) for deployment within a gas turbine engine (18) are provided, as are embodiment of a method for producing the same. In one embodiment, the gas turbine engine cooling system (100) includes an impeller (36) having a hub (52), a plurality of hub bleed air passages (102), and a central bleed air conduit (104). Each hub bleed air passage (102) has an inlet (106) and an outlet (108) formed in outer and inner circumferential surfaces of the hub (52), respectively. The central bleed air conduit (104) is fluidly coupled to the outlets (108) of the plurality of hub bleed air passages (102) and is configured to conduct bleed air discharged by the plurality of hub bleed air passages (102) to a section of the gas turbine engine (18) downstream of the impeller (36) to provide cooling air thereto.
摘要(中):
提供用于在燃气涡轮发动机(18)内部署的燃气涡轮发动机冷却系统(100)的实施例,以及用于生产燃气涡轮发动机(18)的方法的实施例。 在一个实施例中,燃气涡轮发动机冷却系统(100)包括具有轮毂(52),多个毂式放气管道(102)和中央放气管道(104)的叶轮(36)。 每个衬套放气通道(102)分别具有形成在衬套(52)的外圆周表面和内圆周表面中的入口(106)和出口(108)。 中央放气管道(104)流体连接到多个管道放气管道(102)的出口(108),并且被配置成将由多个管道放气管道(102)排放的放出的空气引导到区段 在叶轮(36)下游的燃气涡轮发动机(18)向其提供冷却空气。
