Modeling and Simulation of Electric Propulsion Concepts for a Multimodal Prototype Demonstrator
The Office of Naval Research (ONR) is planning a prototype demonstration of a novel craft envisioned to have three modes of operation: Fuel-efficient, good sea keeping mode for open ocean transits, High-speed, shallow water ...
Flexible Test Bed for MVDC and HFAC Electric Ship Power System Architectures for Navy Ships
Several power architectures have been considered for Navy ships and significant effort has been focused on simulation of the various power system topologies. The University of Texas at Austin Center for Electromechanics ...
The Conceptual Design of a Lightweight Compulsator-Driven Electromagnetic Accelerator
The development of light-weight pulsed power supplies which can deliver significant amounts of energy in a properly conditioned pulse has been an issue throughout the investigation of electromagnetic (EM) launchers and ...
Installation and Commissioning of the 9 MJ Range Gun System 90 mm High L’ Laminated Railgun
In December 1993, The University of Texas at Austin Center of Electromechanics (UT-CEM) completed construction of an high L' railgun for the 9 MJ Range Gun System Program. The 90 mm bore railgun utilizes dispersion ...
9 MJ Range Gun Compulsator Stator Design and Fabrication
The authors provide a summary of the structural analysis of the compulsator stator as well as a detailed description of the major stator components. Fabrication and assembly techniques are also presented, along with the ...
Permanent Magnet Bias, Homopolar Magnetic Bearings for a 130 kW-hr Composite Flywheel
The Center for Electromechanics at the University of Texas at Austin is developing a power averaging flywheel battery for a high speed passenger locomotive as part of the Federal Railroad Administration’s Next
Modeling and Simulation Roadmap to Enhance Electrical Energy security of U.S. Naval Bases
(Office of Naval Research, 2012-04)
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 ...
Some Benefits of Pulsed Alternators as Electromagnetic Gun Power Supplies on Power Systems for Future Electric Ships
An electromagnetic gun provides a new component to be integrated into the power system of an electric ship. Electromagnetic guns have been fired successfully using either capacitors, inductors, or rotating machines to store ...
Thermal Evaluation of High Voltage Hermetic Motors Experiencing Recurrent Insulation Failures
A high voltage hermetic compressor motor design developed for chiller applications has shown recurrent insulation failures in certain stator end-turn regions. Initial investigations found discoloration of failed coil ...
High Power Density and High Efficiency Converter Topologies for Electric Ships
Power electronic converters are expected to be significant contributors to system mass, system loss, and system cost in the all-electric ship, and are therefore a significant area of interest. This paper investigates the ...
