Abstract
An investigation into the feasibility of using widely spaced partially submerged, supercavitating propellers as the means of propulsion for large surface effect ships was carried out at the David W. Taylor Naval Ship Research and Development Center (DTNSRDC) as part of the Advanced Naval Vehicle Concept Evaluation Program. This method of propulsion is shown to be feasible and a performance estimate is developed for an 8,000 ton surface effect ship (SES) with a cushion length to beam ratio of 5. Necessary information is presented for making preliminary performance estimates for similar craft using partially submerged propellers. (Author)
