Comparison of approaches for determining the failure of stiffened cylindrical shells
(Massachusetts Institute of Technology, 2002)
A tool for evaluating the early-stage design of corvettes
(Massachusetts Institute of Technology, 2010)
In naval architecture terminology, the term "corvette" refers to a class of ships that are shorter than frigates and longer than patrol boats. Corvettes have always been the centerpiece of the navies whose mission requirements ...
A frequency domain strip theory applied to the seakeeping of the Zumwalt-Class destroyer
(Massachusetts Institute of Technology, 2010)
Seakeeping analysis of the Zumwalt-Class destroyer was carried out in the framework of linear strip theory and potential flow. First, the problem was formulated and solved analytically. Second, a program called Ship Motions ...
Modular machinery arrangement and its impact in early-stage naval electric ship design
(Massachusetts Institute of Technology, 2012)
Electrical power demands for naval surface combatants are projected to rise with the development of increasingly complex and power intensive combat systems. This trend also coincides with the need of achieving maximum fuel ...
Hydrodynamic evaluation of high-speed semi-SWATH vessels
(Massachusetts Institute of Technology, 2007)
High-speed semi-displacement vessels have enjoyed rapid development and widespread use over the past 25 years. Concurrent with their growth as viable commercial and naval platforms, has been the advancement of three-dimensional ...
Impact and energy absorption of laminated and sandwich composites
(Massachusetts Institute of Technology, 2008)
Advanced fiber reinforced composites combine high specific strength and stiffness. Advanced composites are currently being introduced into modern U.S. Navy ships to achieve weight savings, maintenance reduction, and signature ...
An enhanced propeller design program based on propeller vortex lattice lifting line theory
(Massachusetts Institute of Technology, 2007)
A suite of propeller numerical design tools was developed in MATLAB®, a high-level technical computing language. The tools were based on the FORTRAN programs developed by Professor Justin Kerwin at MIT in 2001 and include ...
Analysis and experiments for contra-rotating propeller
(Massachusetts Institute of Technology, 2011)
Contra-rotating propellers have renewed interest from the naval architecture community, because of the recent development of electric propulsion drives and podded propulsors. Contrarotating propulsion systems have the ...
Impacts of reducing shipboard NOx̳ and SOx̳ emissions on vessel performance
(Massachusetts Institute of Technology, 2010)
The international maritime community has been experiencing tremendous pressures from environmental organizations to reduce the emissions footprint of their vessels. In the last decade, air emissions, including nitrogen ...
Design and analysis of a Non-Pressurized Manned Submersible
(Massachusetts Institute of Technology, 2011)
Non-Pressurized Manned Submersibles (NPMS) have proven their utility in warfare for centuries, demonstrating an unmatched combination of simplicity and versatility in both declared conflicts and undeclared, covert operations. ...
