COOLING APPARATUS FOR A MID-TURBINE FRAME |
摘要 |
A cooling apparatus bifurcates and regulates cooling airflow provided to a mid-turbine frame. The cooling apparatus includes a flow metering tube and a metering plate. The flow metering tube includes a top portion and a tube portion, wherein the top portion includes a first central aperture that directs a first cooling airflow into the tube portion and a first plurality of apertures located circumferentially around the central aperture that directs a second cooling airflow to a portion outside the tube portion. The metering plate is located on the top portion of the flow metering tube, wherein the metering plate includes a second central aperture aligned with the central aperture of the flow metering tube and a second plurality of apertures located circumferentially around the central aperture, wherein a size of the second central aperture meters the first cooling airflow and a size and number of the second plurality of apertures meters the second cooling airflow. |
