The history of the U.S. Naval Ship Design Process is traced over the last 50 years. Descriptions of the products of design are presented for several points in time. Associated organizational changes are traced. Some explanation of the various changes is offered and recommendations for the future are made.
During the early stages of pre‐Contract Definition ship design, the use of computer models now allows the design to be manipulated on a total system basis. That is, a change to any component of the design is immediately and totally reflected in the physical characteristics of the overall ship design. The models that make this possible and the efforts to extend this capability into Concept Development are described. The implications of this for the subsystem designer, in particular the electronics designer, are explored.
Two hydrofoil-nacelle-strut arrays and one hydrofoil-strut array have recently undergone hydrodynamic testing at the David Taylor Model Basin. A calculation procedure for predicting lift and cavitation characteristics of conventional hydrofoil arrays is suggested herein and is compared with the experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
