Abstract: A turbine engine includes a turbine section with a low pressure turbine and a turbine case disposed about an axis. A frame assembly defines an outer cavity and an inner cavity with the outer cavity including at least one opening configured and adapted to communicate cooling air to the turbine case. A transfer tube is disposed within the outer cavity and is configured and adapted to receive cooling air. The transfer tube includes a bend configured to impart circumferential velocity to the cooling air within the outer cavity.

Abstract: A gas turbine engine includes a mid-turbine frame that includes an inner frame case. At least one spoke is connected to the inner frame case. At least one spoke includes a fluid passage that is in fluid communication with a channel on a radially inner end of the fluid passage. The channel is directed in a radially inward and circumferential direction. A cavity is located radially inward from the mid-turbine frame and is in fluid communication with the channel.
Abstract translation: 燃气涡轮发动机包括中间涡轮机框架，其包括内框架壳体。 至少一个辐条与内框架连接。 至少一个辐条包括与流体通道的径向内端上的通道流体连通的流体通道。 通道被引导在径向向内和圆周方向。 空腔从中涡轮机框架径向向内定位并与通道流体连通。
