Linearized Potential Flow Theory for ACVs in a Seaway 



stated above, this coupling between the motion of the ACV and that 



of the water introduces an additional complication in the case of the 



air cushion due to the laws of cushion aerodynamics. 



Also, the IFS is a moving boundary on which the potential is to be 



determined. 



This complicated situation is illustrated in the block diagram
