Relationship of grain boundary structure and mechanical properties of Inconel 690
(Massachusetts Institute of Technology, 2009)
Stress corrosion cracking (SCC), failure due to environmentally assisted crack nucleation and propagation, is an important metallurgical problem with impact on current and future designs of ship structural components and ...
Quasi-static tearing tests of metal plating
(Massachusetts Institute of Technology, 2002)
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 ...
Concept design of a long range AUV propulsion system with an onboard electrical generator
(Massachusetts Institute of Technology, 2012)
Automated Underwater Vehicle (AUV) Technology has come a long way in the past decade. Due to advances in batteries and telecommunications, unmanned underwater vehicles no longer require a tether to a mother ship for power, ...
Cost reduction of polar class vessels : structural optimization that includes production factors
(Massachusetts Institute of Technology, 2013)
The design of ship structures was normally optimized to reduce construction material and maintain adequate strength while adhering to a given classification society's rules. In the case of Polar Class vessels, where weight ...
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 ...
Optimal deadrise hull analysis and design space study of naval special warfare high speed planning boats
(Massachusetts Institute of Technology, 2002)
United States Navy SEALs (Sea, Air, Land) frequently employ high speed planing boats (HSPBs) in the performance of their missions. Operation of these vessels in normal and adverse conditions exposes personnel to severe ...
Improving shipboard maintenance practices using non-intrusive load monitoring
(Massachusetts Institute of Technology, 2007)
(cont.) New casualty parameters were recorded and analyzed in an attempt to verify and expand on diagnostic software currently being developed for the vacuum aided sewage collection system. The analysis of the ships service ...
Deterministic casualty analysis of the Pebble Bed Modular Reactor for use with risk-based safety regulation
(Massachusetts Institute of Technology, 2002)
The resurgence of interest in the use of nuclear technology for electrical power production has resulted in a desire to improve the existing licensing structure. Improving the licensing structure will result in reduced ...
