A two-phase spherical electric machine for generating rotating uniform magnetic fields
(Massachusetts Institute of Technology, 2007)
This thesis describes the design and construction of a novel two-phase spherical electric machine that generates rotating uniform magnetic fields, known as a fluxball machine. Alternative methods for producing uniform ...
Rapidly Estimating Swarm Resource Needs Through Autonomous Simulation
(Massachusetts Institute of Technology, 2023-06)
The maritime industry spends significant time and resources accomplishing long lasting collaborative tasks such as search and rescue or ocean surveying. Autonomous swarm ships’ ability to scale rapidly and operate with ...
Using polymer electrolyte membrane fuel cells in a hybrid surface ship propulsion plant to increase fuel efficiency
(Massachusetts Institute of Technology, 2010)
An increasingly mobile US Navy surface fleet and oil price uncertainty contrast with the Navy's desire to lower the amount of money spent purchasing fuel. Operational restrictions limiting fuel use are temporary and cannot ...
Naval ship propulsion and electric power systems selection for optimal fuel consumption
(Massachusetts Institute of Technology, 2011)
Although propulsion and electric power systems selection is an important part of naval ship design, respective decisions often have to be made without detailed ship knowledge (resistance, propulsors, etc.). Propulsion and ...
Experimental studies of fluid-borne noise generation in a marine pump
(Massachusetts Institute of Technology, 1993)
Vibration suppression in finite length marine cable systems
(Massachusetts Institute of Technology, 1998)
The vibration suppression effectiveness of a flexible in-line marine cable vibration absorber is studied. The transfer matrix method is used to build various numerical models of vibration absorbers in marine cable systems. ...
Machinery monitoring technology design methodology for determining the information and sensors required for reduced manning of ships
(Massachusetts Institute of Technology, 2000)
A comparison of experimental and computational analyses of two dimensional foil sections
(Massachusetts Institute of Technology, 2000)
Flexibility in early stage design of US Navy ships : an analysis of options
(Massachusetts Institute of Technology, 2011)
This thesis explores design options for naval vessels and provides a framework for analyzing their benefit to the Navy. Future demands on Navy warships, such as new or changing missions and capabilities, are unknowns at ...
Submarine design optimization using boundary layer control
(Massachusetts Institute of Technology, 1997)
