Experiments of the DARPA (Defense Advanced Research Projects Agency) Suboff Program

Abstract : Experimental measurements of the flow field of an axisymmetric body, bridge fairwater, four identical symmetric stern appendages, and two ring wings with ring wing support struts will be made in the David Taylor Research Center (DTRC) Anechoic Flow Facility (AFF) and deep-water towing basins (TMB) and Tracor Hydronautics Ship Model Basin (HSMB). The experimental data will be used to assess the current Computational Fluid Dynamics capability for the Defense Advanced Research Projects Agency (DARPA) SUBOFF Project. Experimental facilities and techniques are presented, and the contents of the experiments are outlined. This information together with the geometric characteristics of DARPA SUBOFF models is intended for use by both the model test engineers and the CFD engineers.
