Unsteady Skin-Friction Measurements on a Maneuvering Darpa2 Suboff Model
Steady and unsteady flow over a generic Suboff submarine model is studied. The skin-friction magnitudes are measured by using hot-film sensors each connected to a constant temperature anemometer. The local minima in the skin-friction magnitudes are used to obtain the separation locations. Steady …

Steady and Unsteady Maneuvering Forces and Moments on Slender Bodies
… length of the body. The two bodies are the DARPA Suboff generic submarine shape and a non-Body-of-Revolution scalene ellipsoid with a constant cross-section midbody. An analytical two-mode equation has been shown to accurately describe the normal force and pitch moment as well as side force and …

Contributions to the Understanding of Turbulent Boundary Layers Over Curved Walls
… campaign was conducted to investigate the DARPA Suboff boundary layer. To emphasize the axisymmetric boundary layer, the generic submarine model's sail, appendages, and propeller were omitted. The study focused on the afterbody from 70–95% of the model length to examine the concurrent pressure …

A Hydrodynamic Analysis and Conceptual Design Study for an External Storage Enclosure System for Unmanned Underwater Vehicles.
… rigid multi-bodied UUV built around DARPA’s SUBOFF hull from, the goal being to develop new and innovative low-cost methods of modifying commercially available UUVs to enhance range, payload capabilities and sensory performance through the use of novel external enclosure systems. This thesis …

Analysis of the operational impacts of alternative propulsion configurations on submarine maneuverability
… and empirical data obtained from the DARPA SUBOFF submarine hullform. This model was analyzed for two configurations: ** A centerline shaft configuration utilizing cruciform control surfaces for yaw and pitch control; ** A podded configuration utilizing pods for propulsion as well as yaw and …
