Experiments of the darpa suboff program

WebThe geometry used in the present work is the generic submarine hull, DARPA SUBOFF without appendages (AFF1) (Groves et al. 1989). Figure1shows both fully appended hull (AFF8) and bare hull (AFF1) SUBOFF geometries. The SUBOFF geometry has been used in numerous past experiments and simulations. WebThe numerical results have been compared with the experiments. The self- propulsion performance of DARPA SUBOFF has been computed for two different velocities.
