Abstract
A windage management arrangement for attenuating fluid flow disturbances on an actuator and a moving disc, comprising in combination a fluid flow stripper upstream of the actuator and a disc edge damper downstream of the actuator. A method for managing fluid flow created by a rotating disc that is operably disposed adjacent to an actuator, comprising diverting an upstream portion of the fluid flow, with respect to the actuator, away from the actuator; and diverting a downstream portion of the fluid flow, with respect to the actuator, away from a disc edge.
