The proposed research is directed toward the improvement of the relationships used during the early stages of U.S. Navy aircraft carrier design for estimating weights, vertical centers of gravity (KG) and required areas and volumes. The principal focus will be on updating the relationships used in the NAYSEA Aircraft Carrier Design-Synthesis Model. Specific objectives will be as follows: (a)To provide a consistent weight, KG and area/volume database, as derived from the design documentation for previous aircraft carriers, (b)To take into account any changes in aircraft carrier design practices, especially at the subsystem level, which have occurred in recent years, the aircraft carrier design-synthesis model in recent years (e.g. the hull form generation capability) in order to increase the accuracy of the estimates for a new design, and (c)To make use of techniques developed during nine years of experience in updating the estimating algorithms for the NAVSEA Destroyer Design-Synthesis Model.
