Abstract:

Techno-Sciences, Inc. (TSi), in collaboration with the Smart Structures Laboratory of the Alfred Gessow Rotorcraft Center at the University of Maryland, propose to develop a semi-active Magnetorheological Fluid-Elastic (MRFE) snubber damper utilizing a low-cost, fully controllable magnetorheological damper in an existing elastomeric snubber/damper. The MRFE snubber/damper will increase flexbeam life, extend the stability envelope for air resonance, and extend damper life. The MRFE snubber/damper system will augment damping inflight only when required as commanded by the controller. To enable retro-fit to existing rotor systems, the electrical power required to operate the actuator will be drawn from the DC power bus supplying the main rotor de-icing system.
