Superior hydrodynamic performance of US Navy ships, submarines, and underwater vehicles is critical in order for them to conduct their missions effectively.  For a surface ship, hydrodynamic performance addresses seakeeping, maneuvering, and capsizing while for a submarine or submerged vehicle it covers stability, control, and maneuvering.  The first part of this talk will highlight some results of recent studies that examined issues for surface ship hydrodynamic performance.  These include the altered turning behavior in a wave field compared to calm water, the practicality of applying linear theory for seakeeping performance in a multidirectional seaway, and the usefulness and limitations of steep regular wave testing as a means to identify operating conditions that are susceptible to capsize.  The second portion of the talk will highlight some emerging areas of interest regarding the performance of submarines and underwater vehicles.  Topics will include minimizing the difficulties involved with obtaining quantitative flow field measurements around scale-models in large hydrodynamic facilities, understanding the consequences of forward generated flow disturbances on the performance of aft control surfaces and propellers, and developing capabilities to predict the unsteady loads generated during near surface operations in a seaway.  These topics represent challenges that can be addressed with fundamental research to help understand real-world Navy problems.



Dr. Joseph T. Klamo is an Assistant Professor in the Systems Engineering Department at the Naval Postgraduate School. His research interests include the seakeeping, maneuvering, and capsize of surface ships and the stability, controllability, and maneuverability of submarines and underwater vehicles. He is also interested in the quantification and management of uncertainty with respect to experimental hydrodynamic testing of scale-models. Previously, he worked at the Naval Surface Warfare Center, Carderock Division in West Bethesda MD from 2007 to 2015, most recently as group leader of Captive Model Testing in the Division of Submarine Maneuvering and Control. Professor Klamo received both his Ph.D. (2007) and M.S. (2002) degrees in Mechanical Engineering from the California Institute of Technology in Pasadena, CA. He received his B.S.E. (2001) in Mechanical Engineering from the University of Michigan in Ann Arbor, MI.
