Abstract
The positions of brush seal segments are positively adjusted relative to a housing carrying the brush seal segments and the opposing sealing component by employing members formed of thermally responsive material. The members are heated by heating elements receiving controlled power. By increasing or decreasing the power provided to the heating elements, the members are expanded or contracted to move the brush seal segments toward or away from the opposing sealing component.
