Title: Data reduction, analysis and results of LACV-30-07 Air Cushion Vehicle tests, Fort Story, VA, August-September 1993
Description: 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.
