Design space exploration and optimization using modern ship design tools
(Massachusetts Institute of Technology, 2014)
Modern Naval Architects use a variety of computer design tools to explore feasible options for clean sheet ship designs. Under the Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center, Carderock Division ...
Design of an Autonomous Underwater Vehicle (AUV) charging system for underway, underwater recharging
(Massachusetts Institute of Technology, 2014)
Modern robotics have enabled the rapid proliferation of Autonomous Underwater Vehicles (AUVs) throughout the marine environment. As autonomy algorithms increase in robustness, complexity, and reliability, so too does the ...
Analysis of consistently poor work estimates in U.S. submarine availabilities
(Massachusetts Institute of Technology, 2018)
The maintenance of a warship requires an involved combination of scheduling, funding, and execution. For one finite maintenance period, known as an "availability," a small setback in one of these areas can have a significant ...
An automatic, multi-fidelity framework for optimizing the performance of super-cavitating hydrofoils using Gaussian process regression and Bayesian optimization
(Massachusetts Institute of Technology, 2018)
Computer automated design of complex physical systems is often limited by the computational resources required for the high precision solvers. Determining an optimum design necessitates high accuracy simulations due to the ...
Multipath arrival tracking for marine vehicles utilizing pattern recognition
(Massachusetts Institute of Technology, 2018)
In recent years, interest in the Arctic Region has been steadily growing as it has become more accessible due to continued ice recession. This increased accessibility opens up the possibility for nations to take advantage ...
Load bearing interface design for a pan-tilt mechanism for severe marine environments
(Massachusetts Institute of Technology, 2017)
The Naval Research Laboratory (NRL) requested the design of a two-axis gimbal device for the shipboard support of a sensor payload. Previous design efforts presented a low-mass two-axis (pan and tilt) machine. Vibration ...
Integrating Model Based Engineering and trade space exploration into naval acquisitions
(Massachusetts Institute of Technology, 2016)
The Navy Acquisition force is faced with designing, procuring, and managing some of the most complex systems and technologies imagined. Balancing a shrinking and fickle budget environment with a program that has dynamic ...
An experimental study of the one Atmosphere Diving Suit (ADS) and data analysis of military diving
(Massachusetts Institute of Technology, 2016)
The Atmospheric Diving Suit (ADS) is a one-man submarine with moveable, humanlike appendages with internal pressure maintained at one atmosphere. This precludes the possibility of common diving related illnesses while ...
Mechanical characterization of lithium-ion battery micro components for development of homogenized and multilayer material models
(Massachusetts Institute of Technology, 2014)
The overall battery research of the Impact and Crashworthiness Laboratory (ICL) at MIT has been focused on understanding the battery's mechanical properties so that individual battery cells and battery packs can be ...
Risk-based treatment of uncertainty in trade space exploration : application via Monte Carlo simulation on a manned, mini-submersible model
(Massachusetts Institute of Technology, 2018)
In design, modeling and simulation are commonly used to answer questions of interest as it is both inefficient and expensive to physically build and evaluate numerous possibilities. Any modeling effort aims to build the ...
