A SIMPLIFIED REPRESENTATION OF THE VERTICAL PLANE DYNAMICS OF SES CRAFT

The basic dynamics of sidewall-type surface effect ships for vertical plane motions (heave and pitch) in response to waves is established in terms of the fundamental frequency characteristics and other critical parameters that affect craft motion. The effects of leakage variations and seal action in producing pressure variations, vehicle accelerations, and motions, etc., are illustrated by time histories of motion variables via computer simulation. The vehicle's basic dynamic characteristics provide insight into the different aspects of control that may be applied to achieve improved motion and habitability performance. A discussion of the problems associated with scaling model test results, together with techniques for the proper prediction of full-scale dynamic performance, also is provided.
