An Analytical Method for Estimating Limiting Velocities of Captured Air Bubble Vehicles as a Function of Sea State

Abstract

The captured air bubble vehicle achieves lift in a manner similar to that of a planing surface but with one major exception. The boat rides on a volume of air trapped between its bottom and the water surface by sideboards on the sides and movable seals (small planing skis) fore and aft. In smooth water operation the skis do not have to move up and down to retain the trapped air and the volume of trapped air remains constant. However, when the vehicle is traveling over waves the situation becomes quite complex. The report attempts to determine the limitations resulting from operation over waves by considering several idealized modes of operation.
