Propeller performance analysis using lifting line theory
(Massachusetts Institute of Technology, 2009)
Propellers are typically optimized to provide the maximum thrust for the minimum torque at a specific number of revolutions per minute (RPM) at a particular ship speed. This process allows ships to efficiently travel at ...
Hardware model of a shipboard generator
(Massachusetts Institute of Technology, 2009)
A hardware model of the Gas Turbine Generator (GTG) in use on the US Navy's DDG-51 Class Destroyer is constructed for use as a lab apparatus at the Massachusetts Institute of Technology's Laboratory for Electromagnetic and ...
Cooling system design tool for rapid development and analysis of chilled water systems aboard U.S. Navy surface ships
(Massachusetts Institute of Technology, 2013)
Over the last several decades, there has been a dramatic increase in the complexity and power requirements of radars and other combat systems equipment aboard naval combatants and this trend is expected to continue for the ...
Design of an AUV recharging system
(Massachusetts Institute of Technology, 2004)
The utility of present Autonomous Underwater Vehicles (AUVs) is limited by their on-board energy storage capability. Research indicates that rechargeable batteries will continue to be the AUV power source of choice for at ...
Desktop systems for manufacturing carbon nanotube films by chemical vapor deposition
(Massachusetts Institute of Technology, 2007)
Carbon nanotubes (CNTs) exhibit exceptional electrical, thermal, and mechanical properties that could potentially transform such diverse fields as composites, electronics, cooling, energy storage, and biological sensing. ...
Shipboard aggregate power monitoring
(Massachusetts Institute of Technology, 2009)
Modem naval warships rely on vast arrays of sensor networks to evaluate the performance of mission critical systems. Although these sensor networks enable increased levels of automation, they are costly to install and to ...
Cooling system early-stage design tool for naval applications
(Massachusetts Institute of Technology, 2011)
This thesis utilizes concepts taken from the NAVSEA Design Practices and Criteria Manualfor Surface Ship Freshwater Systems and other references to create a Cooling System Design Tool (CSDT). With the development of new ...
Analysis of the operational impacts of alternative propulsion configurations on submarine maneuverability
(Massachusetts Institute of Technology, 2011)
In an effort to develop submarine designs that deliver reduced size submarines with equivalent capabilities of the current USS VIRGINIA (SSN-774 Class) submarine, a joint Navy/Defense Advanced Research Projects Agency ...
Operational profiling and statistical analysis of Arleigh Burke-class destroyers
(Massachusetts Institute of Technology, 2013)
Ship operational profiles are a valuable tool for ship designers and engineers when analyzing potential designs and ship system selections. The most common is the speed-time profile, normally depicted as a histogram showing ...
Energy storage and dissipation in polyurea composites
(Massachusetts Institute of Technology, 2013)
Polyurea composites have been of interest for a variety of engineering applications via their highly dissipative yet resilient behavior under deformation. Polyurea composites have been considered as a self-healing and ...
