The LACV-30-07 Air Cushion Vehicle was instrumented and tested at Fort Story, VA during the months of August-September 1993 by Ed. Thomas, NSWC-Cardrock Division, Annapolis Detachment, Annapolis, MD. The tests include 27 cuts with vehicle speed ranging from 0 to 42 knots and approximate wave height of 0 to 2.5 feet. Two triaxial accelerometers, and a pitch and roll transducer were installed to measure axial, transverse and vertical accelerations and pitch and roll (in degree) of the vehicle. The test results clearly show that the vibration g-amplitude is extremely low (fraction of 1-g level) for air cushion vehicle and air cushion vehicle itself is acting as a super-damper to reduce the wave-induced vibration response amplitude. The vibration amplitude in terms of g-level may not be the controlling factor, but the combined vehicle dominant frequencies, vibration g-level, and duration may be the definite factors that the superconductor magnet must persist.
