Abstract
A blade damper with a magnetic contaminants trap includes, a housing defining a cavity, a piston in operable communication with the housing dividing the cavity into at least a first chamber and a second chamber, a passageway in operable communication with the cavity configured to allow fluid within the cavity to move between the first chamber and the second chamber through the passageway, and at least one magnet in operable communication with fluid in at least one of the cavity and the passageway, such that magnetic contaminants are prevented from freely moving about within the fluid after having been attracted toward the at least one magnet by a magnetic field of the at least one magnet.
