Abstract

A flow metering and retention system includes a first disk that is annular in shape surrounding a centerline and extending axially along the centerline, a first coverplate axially rearward of the first disk with the first coverplate having an axially rearward extending arm, a second disk that is annular in shape surrounding the centerline and rearward of the first coverplate, a second coverplate at least partially between the first coverplate and the second disk; and a ring adjacent to the radially outer side of the slot of the second disk. The second disk has a slot into which the arm of the first coverplate extends with the slot having a radially outer side and a radially inner side, and the ring is configured to meter air flowing between the radially outer side of the slot and the arm of the first coverplate.
