|
 | The enhancement of the electrical energy security of Navy bases within the continental U.S. has been studied using an approach based on modeling and simulation, with the intent to achieve real time control and energy management. The commercially available software packages are reviewed and the most suitable ones are indicated. A notional base was developed and used for this study. Its format is general enough to be able to be ... |

|
| This report describes methods for retrofitting legacy hydraulic systems, particularly evaluating means for generating and verifying retrofit or new system design requirements. Methods that combine physics-based modeling, simulation, and design techniques are described and applied to a submarine control surface actuator retrofit problem. First, an integrated submarine/actuator subsystem model is developed for simulation-based design requirements generation. Simulations are used to derive power and energy storage requirements for control surface actuation ... |

| This report is Volume 2 of a three-volume Final Report on ONR Contract N00014-07-C-0361. Activities documented in this report were performed as a supplement to ONR Grant N00014-06-01-0886. The two programs address the use of energy storage and high speed power generation to reduce fuel consumption of DDG-51 Arleigh Burke class ship service generation system by improving efficiency and permitting safe operation on one gas turbine generator set. In the ... |

|
| Part of the technical versatility of future all-electric ships is the potential ability to share large amounts of power among a variety of high power loads. To help evaluate this potential and to provide information to help guide technology selection, a physics-based model of a power train for an electric ship has been developed and implemented on three modeling platforms. Using this model, three different investigations have been carried out ... |

| The U.S. Marine Corps Marine Family of Fighting Vehicles (MEFFV) program is focused on developing a fighting vehicle that is survivable and lethal on the battlefield of 2020 and beyond. One vehicle variant seeks to exploit synergies between electric mobility and electric armament systems by employing a hybrid electric mobility propulsion system and an electric gun for an all Electric MEFFV. The objective of this project was to determine the ... |

| Under contract DAAEO7-98-C-L020 testing was conducted at the U.S. Army Yuma Proving Grounds by the U.S. Army Tank-automotive and Armaments Command, Research, Development and Engineering Center and the University of Texas Center for Electromechanics during 8, 9, and 10 November 1999 between an active (electromechanical suspension) and passive High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) to determine performance improvements. Two tests, RMS courses and Lane ... |

|
 | Test results are presented from pressurizing thick-walled, hoop-wound graphite fiber composite rings to very high internal radial pressures. Hydraulic pressures exceeding 275 MPa (40000 psi) were obtained. The testing was performed on rings wound with two different resins: a cyanate ester and a bismaleimide (BMI) resin. To prevent axial delaminations at these high pressures, a thin bi-directional G11 cloth lining was used inside the rings. The rings were monitored with ... |

|
| Both linear (railgun) and coaxial (mass driver, etc.) electromagnetic launchers (EMLS) are treated as time-varying impedances to determine the relationships between acceleration force, payload velocity, and power supply voltage and current. These relationships are then examined in the light of electromagnetic parameters associated with each EML type ot establish a basis for determining and comparing power supply requirements for various EMLs. |
