Knowledge acquisition for marine propeller design C. Dai, L. Mulvihill David Taylor Model Basin, U.S. Navy, Bethesda, Maryland, MD 200&?-JOOO, L/5W ABSTRACT Preliminary propeller design requires rapid turn around so that engineer can evaluate as many design candidates as possible and thus time is of essence. Approximate model based on simplifying assumptions such as potential flow theory based computational methods, rules of thumb and historical data are used in modern propeller design. Marine propeller design is an iterative process that compromises must be made between various conflicting requirements. The designer must perform a series of tasks repeatedly and sequentially to arrive at some final design that will satisfy the requirements. Use of a knowledge based (KB) system as a design aid for propeller design can greatly reduce the time and cost of propeller design. The major bottleneck in any knowledge based system is knowledge acquisition. This paper discusses an
