Hovercraft Rigid Body Response to Free Field Airblast

Abstract

Vehicles in the class of surface effect ships (SES) and air cushion vehicles (ACV) respond to airblast loading in a manner different from that of conventional displacement-type ships. The SES/ACV class of vehicles has low hydrodynamic drag resistance to motion response and the air cushion chamber which levitates the vehicles can interact with the blast wave. The rigid body response of a hovercraft (ACV) in an airblast environment was investigated by conducting free field HE explosive tests. The airblast loading was of short duration (25-35 msec free field positive phase). The results are discussed.
