SURFACE SHIP & SUBMARINE HULL MECHANIC & ELECTRICAL (HM&E)
Abstract
Efforts include: signature reduction, hull life assurance, hydromechanics, distributed control for automated survivability (includes damage control), and advanced electrical power systems. Signature reduction addresses electromagnetic, infrared, and acoustic signature tailoring, both topside and underwater. Hull life assurance addresses development of new structural system approaches for surface ships and submarines, including the management of weapons effects to control structural damage and the improvement of structural materials. Hydromechanics addresses hydrodynamic technologies, including the signature aspects of the hull-propulsor interface and maneuvering. Distributed intelligence for automated survivability addresses both the basic technology of automating damage control systems, as well as, distributed control of systems utilizing self-healing capability. Advanced electrical power systems efforts address electrical and auxiliary system and component technology to provide improvement in energy and power density, operating efficiency and recoverability from casualties. Advanced Naval Power efforts include: Compact Power Conversion Technologies that reduce the cost of high power conversion equipment required to enable more-electric and all-electric ships. This activity also supports the Overseas Contingency Operations (OCO) Counter IED - Extramural activity which supports applied research for force protection of Naval platforms. Technologies are being developed that focus on prediction, prevention, detection, neutralization, and mitigation of improvised explosive devices in the maritime/littoral environment. The funding decrease from FY 2009 to FY 2010 is due to the completion of the energy and power technology initiative that accelerated research in the following Energy and Power efforts: Distribution/Control and Alternative Energy efforts, Energy Storage and Power Generation efforts and the Medium Voltage Direct Current (MVDC) architecture efforts in support of the Next Generation Integrated Power System (NGIPS) Roadmap efforts. The decrease also represents the phased movement of Future Naval Capability Enabling Capabilities Compact Power Conversion Technologies from Applied (6.2) to Advanced (6.3) Research as the technologies mature and prepare for transition to acquisition. The funding increase from FY 2010 to FY 2011 is due to the start up and initiation of modeling of hydroacoustics of turbulence-propulsor interaction; the effort on exploitation of polymers for the deflection of dissipation of shock wave impact on ship and submarine hull structures; transition of small scale hardware-in-the-loop demonstrator to the academic community for challenge problem formulation and demonstrations of developed model based reasoning control algorithms on full scale hardware test beds.
