  • Gas turbine engine disk rim with axially cutback and circumferentially skewed cooling air slots
    Patent number: 6749400
    Abstract: A gas turbine engine rotor disk assembly includes a disk having an annular hub circumscribed about a centerline. An annular web extends radially outwardly from the hub to an annular rim. A plurality of dovetail slots extend generally axially through the rim. A plurality of cooling air slots extending generally radially through the rim and are skewed circumferentially with respect to the centerline and slanted axially aftwardly with respect to a normal radius perpendicular to the centerline. In the exemplary embodiment, each cooling air slot has parallel side walls skewed circumferentially with respect to the centerline and an aft wall extending between the side walls and slanted axially aftwardly with respect to the normal radius. The side walls are skewed circumferentially about 5 degrees with respect to the centerline and the aft wall is slanted axially aftwardly about 18 degrees with respect to the normal radius.
