Abstract
An engine includes a rotational assembly and a bearing assembly. The rotational assembly includes a shaft rotatable about a rotational axis. The bearing assembly includes a housing and a bearing. The housing surrounds and forms a bearing compartment. The housing includes a housing body extending circumferentially about the rotational axis. The housing body forms a first air flow path and a second air flow path. The first air flow path extends from a first inlet plenum to a first outlet plenum. The second air flow path extends from a second inlet plenum to a second outlet plenum. The second air flow path is disposed between and separating the first air flow path and the bearing compartment. The bearing is disposed within the bearing compartment. The bearing is rotationally engaged with the shaft.
