Abstract
A gas turbine engine includes a bearing structure mounted to the front center body case structure to rotationally support a shaft driven by a geared architecture. A bearing compartment passage structure is in communication with the bearing structure through a front center body case structure.
Claims20
A gas turbine engine comprising:
- a front center body case structure;
- a geared architecture at least partially supported by said front center body case structure;
- a bearing structure mounted to said front center body case structure to rotationally support a shaft driven by said geared architecture;
- and
- a bearing compartment passage structure in communication with said bearing structure through said front center body case structure.

A method of communicating a buffer supply air for a gas turbine engine comprising:
- communicating a buffer supply air across an annular core flow path;
- and
- communicating the buffer supply air through a hollow front center body strut of a front center body case structure which defines the annular core flow path, the hollow front center body strut within the annular core flow path.
A method of communicating a buffer supply air for a as turbine engine comprising:
- communicating a buffer supply air across an annular core flow path;
- communicating the buffer supply air to a bearing structure mounted to a front center body case structure which defines the annular core flow path, the bearing structure rotationally supporting a shaft driven by a geared architecture;
- driving a fan through the geared architecture, the bearing structure axially located between the fan and the geared architecture;
- and
- communicating the buffer supply air to a spinner supported by the fan.
