Hydrodynamics of DARPA SUBOFF Submarine at Shallowly Immersion Conditions [PDF]
TransNav, 2019 Recently, the submarine missions are often evolving into operating to littoral areas, which require operating in shallow water. Such shallow water operations strongly contrast with the traditional ones due to the effect of a close to free water surface ...

Journal of Marine Science and Engineering, 2023 Submarines with pumpjet propulsors have recently been used in many countries to improve their propulsion and noise performance. The pumpjet has the advantage of improving noise and cavitation performance by increasing the pressure inside the duct, and it

Measurement of Turbulent Wake behind a SUBOFF Model and Derivation of Experimental Equations [PDF]
Journal of the Korea Institute of Military Science and Technology, 2011 This paper presents the experimental result to investigate the characteristics of turbulent wake generated by submarine. A SUBOFF nude model which was assumed as an axial -symmetric body was used to create wake, and a thin strut was mounted on the top of the model.
