Abstract:
Magnetostrictive Bi-Directional Linear Actuator
This project involves the conceptual design of a hydraulic bi-directional linear
actuator. A "hydraulic actuator" built using the firm's concept would require no
separate hydraulic power source, no hydraulic valves of any kind, would have much
higher frequency response and resolution than conventional technology, would be fast,
and able to exert large forces. Resolutions of .00002 inches with velocities of 100
inches per second are achievable with bandwidths exceeding 1000 hertz. There is no
other linear actuator technology that can come even close to this performance.
This system represents an entirely new class of hydraulic actuator that could also
be used as a pump. If optimized for resolution, it could be used to meter fluids
or gases at high resolution. If built larger and optimized for flow rate, it could
be used as an ultra-quiet (no propeller and no moving parts) propulsion system for
torpedoes or similar ordnance.
