Conceptual design of a 30 ft. self-propelled monoform model

Abstract

An investigation was directed at determining whether the Submarine Control System Test Vehicle (CSTV), could be used as the underwater hull for the Monoform (a small waterplane area ship).

Hydrostatic and static stability considerations formed a basis for obtaining an optimum strut configuration for the hull. Two hull forms were. considered. The model was scaled to a 2000-ton prototype to obtain the necessary geometry for a full scale vessel.

Two computer programs were developed and are outlined together with the derived formulae used in them. Stability curves help establish the design's conformance with requirements laid down by the US Navy.

The results indicate that not only could the CSTV be effectively used as the underwater hull for the Monoform but also that the chosen design exhibits exceptionally good stability characteristics.

A set of model experiments designed to assess the Monoform's performance in calm water and waves (seakeeping) as well as to ascertain the speed-power relationships are also recommended in this report.
