Abstract:
1. An airflow control system, comprising: an airflow control device cooperatively positioned about a component, wherein the airflow control device comprises a first planar surface comprising a plurality of openings and at least one additional planar surface comprising a plurality of openings, wherein the first and at least one additional surfaces have a sliding engagement relationship, wherein the plurality of openings of the first surface coaxially align with the plurality of openings of the at least one additional surface at different positions in the sliding engagement relationship wherein an active material is in operative communication with the planar surfaces to effect the sliding engagement; and an activation device, in operative communication with the active material and being operative to change at least one attribute in response to an activation signal and provide in-plane movement of the first and the at least one additional planar surfaces, wherein an airflow through the airflow control device changes with the change in the at least one attribute of the active material.
