National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Geometric Characteristics of DARPA (Defense Advanced Research Projects Agency) SUBOFF Models (DTRC Model Numbers 5470 and 5471).

ADA210642

Publication Date	1989
Personal Author	Groves, N. C.; Huang, T. T.; Chang, M. S.
Page Count	90
Abstract	The Submarine Technology Program Office of DARPA funded a concerted and coordinated computational fluid dynamics program to assist in the development of advanced submarines for the future. The DARPA SUBOFF project will evaluate, in a competitive environment directly against model test results, flow field predictions of an axisymmetric hull model with and without appendages. The model configurations were designed at DTRC and are given in this report. An axisymmetric body, fairwater, symmetric stern appendages, two ring wings and ring wing support struts were designed for DARPA SUBOFF project. Two geometrically identical models, designed to a linear scale ratio of 24, will be constructed to allow simultaneous testing in different facilities. Geometrical details of all components, including defining equations with computer code listings, are provided. The locations of velocity measurement stations and of surface pressure taps are also given. This information is intended for use by both the model test engineer and the CFD engineer. Keywords: Submarine hull models; Shroud struts; Pressure measurement; Geometric forms. (EDC)
