Abstract
A seal for a rotary machine includes a flexible element extending circumferentially about a rotating component and extending generally radially from a first end to a free second end. The flexible element is coupled proximate the first end for rotation with the rotating component. The seal also includes a retaining plate having a stop face that orients the flexible element at a first angle when the rotating component is operating at less than a critical speed and under the including of pressure loading, such that a clearance gap is defined between the free second end and a stationary component. The flexible element extends at substantially a second angle when the rotating component is operating at a speed greater than the critical speed, such that the flexible element forms a dynamic seal between the rotating component and the stationary component.
