    Abstract: A sealing assembly for a bearing compartment of a gas turbine engine includes a shaft and a seal plate mounted to the shaft. The shaft is configured to rotate about a longitudinal axis of the gas turbine engine. The seal plate includes an annular body, scoop, sealing surface, plurality of teeth, and channel. The scoop is connected to and extends radially from the annular body. The scoop defines a lip and an annulus surrounding the shaft and is disposed on a first axial end of the annular body. The sealing surface is disposed on a second axial end of the annular body opposite from the scoop. The plurality of teeth are disposed into and along an outer perimeter of a portion of the annular body. The channel extends through a portion of the annular body and is fluidly connected to the scoop and to the sealing surface.

    Abstract: A casing for a fan drive gear system includes a cast body with an upper and a lower portion. The cast body defines an oil inlet and an oil outlet arranged below the oil outlet. An integrally cast oil channel extends between the inlet and outlet for conveying oil from the upper portion of the cast body portion to the lower portion of the cast body for providing a supply of lubrication to the gear system when oil pools in an upper portion of an auxiliary oil reservoir during negative-G flight events.

    IPC: F02C7/06

    Abstract: A bearing assembly for a gas turbine engine includes, among other things, a bearing housing extending along an axis to define a bearing compartment, a lubricant seal assembly adjacent to the bearing housing to bound the bearing compartment, an air seal assembly defining a vent cavity along the bearing housing, wherein a mixing cavity is defined between the lubricant seal assembly and the air seal assembly, and wherein the bearing housing defines an airflow supply passage, an airflow vent passage and a scupper passage having respective fluid ports at different circumferential positions relative to the axis, the fluid port of the airflow vent passage fluidly coupled to the vent cavity, and the fluid ports of the airflow supply and scupper passages fluidly coupled to the mixing cavity. A method of sealing for a gas turbine engine is also disclosed.
