Vulnerability analysis of an all-electric warship
(Massachusetts Institute of Technology, 2010)
Traditional design processes usually rely on cost as the metric the designer uses to select among different alternatives. Sometimes when costs cannot be calculated we use weight, volume and efficiency as surrogates for ...
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 ...
A quantitative methodology for mapping project costs to engineering decisions in naval ship design and procurement
(Massachusetts Institute of Technology, 2010)
Alternative methods for cost estimation are important in the early conceptual stages of a design when there is not enough detail to allow for a traditional quantity takeoff estimate to be performed. Much of the budgeting ...
Hardware model of a shipboard zonal electrical distribution system (ZEDS) : alternating current/direct current (AC/DC)
(Massachusetts Institute of Technology, 2010)
A hardware model of a shipboard electrical distribution system based on aspects of the DDG 51 Flight IIA, Arleigh Burke class, 60Hz Alternating Current (AC) and the future direct current (DC), zonal electrical distribution ...
Open architecture framework for improved early stage submarine design
(Massachusetts Institute of Technology, 2010)
Could transparency between current disparate methods improve efficiency in early stage submarine design? Does the lack of transparency between current design methods hinder the effectiveness of early stage submarine design? ...
Exploring the use of Model-Based Systems Engineering (MBSE) to develop systems architectures in naval ship design
(Massachusetts Institute of Technology, 2010)
The U.S. Navy designs and operates the most technologically advanced ships in the world. These ships incorporate the latest in weapons technology, phased array antennas, composite structures, signature reduction, survivability, ...
A tool to create hydrodynamically optimized hull-forms with geometrical constraints from internal arrangements
(Massachusetts Institute of Technology, 2013)
Internal arrangements and bulky equipment like machinery have been treated for many years as a secondary aspect of the ship design. Traditionally, in the design process, the centerpiece of the effort is the hull and its ...
Applying set based methodology in submarine concept design
(Massachusetts Institute of Technology, 2010)
Early stage ship design decisions continue to be a challenge for naval architects and engineers. The complex interactions between the different elements of the ship and the broad spectrum of disciplines required in ship ...
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 ...
