THE DOMAIN OF THE SURFACE EFFECT SHIP

Open publisher page 0 citations

Abstract

The development of the surface-effect ship is traced from its inception to the present day, and its accomplishments and problems are discussed. The SES is compared with other advanced marine craft from all aspects of design and operation. It is determined that the SES is the only advanced craft that does not suffer from either size or speed limitations. The variation of speed and ride characteristics in a sea state are explored to develop the probable operating domain of the SES. Continued subsystem development in seals, propulsion, lift and structural systems is discussed and estimates are made of improved operating efficiencies that could result. Specific application in both naval and commercial service are reviewed. The values of direct operating costs associated with a wide range of operations are presented. These substantiate the competitive status of SES. It is concluded that the SES has a good operating potential for designs of varying length/beam ratio.
