Combined tensile-compressive biaxial loading of Li-ion battery components
(Massachusetts Institute of Technology, 2018)
Lithium-ion batteries under a mechanical load can develop failures in the internal multi-layer structure. Due to the flammable materials required for construction, the safety of the battery has been in question since it ...
Numerical and experimental investigation of the effect of an inverted bow on the hydrodynamic performance of Navy combatant hull forms
(Massachusetts Institute of Technology, 2015)
In this paper we investigate the resistance and seakeeping effects of an inverted bow by comparing the motions of an existing combatant hull, the Oliver Hazard Perry class frigate (FFG-7), with a modified version of the ...
Model testing and computational analysis of a high speed planing hull with cambered planing surface and surface piercing hydrofoils
(Massachusetts Institute of Technology, 2015)
As part of a 2014 thesis, the MIT Innovative Ship Laboratory (iShip) designed a high-speed planing hull form that was based on the Model Variant 5631 developed at the US Navy's David Taylor Model Basin [7] [3] [5]. This ...
Slip clutch design for position sensitive systems in marine environments
(Massachusetts Institute of Technology, 2017)
The Naval Research Laboratory (NRL) requested a two-axis pan tilt mechanism be designed, built, and tested for shipboard deployment of a sensor payload. Of paramount consideration to this design was the robustness of the ...
An investigation into the design of surface piercing super cavitating hydrofoils
(Massachusetts Institute of Technology, 2017)
The fluid-dynamic design of hydrofoils to support marine crafts at high speeds has received growing interest in recent years. Physics involved in the design of high-speed surface-piercing hydrofoils is complex involving ...
Next generation probabilistic prediction model for submarine propulsion shaft life
(Massachusetts Institute of Technology, 2018)
With the development of the U.S. Navy's new COLUMBIA class ballistic missile submarine, the Navy plans to implement a new, longer operational inspection interval for the propulsion shaft system, attempting to double the ...
Engineering a human Factors analysis of a novel one Atmosphere Diving Suit (ADS) elbow joint
(Massachusetts Institute of Technology, 2018)
An Atmospheric Diving Suit (ADS) is a one person anthropomorphic submersible which is used to facilitate undersea work while keeping the diver/operator at atmospheric pressure thus removing them from the harmful physiological ...
Naval applications of enhanced temperature, vibration and power monitoring
(Massachusetts Institute of Technology, 2015)
Navy ships require reliable information regarding their power and mechanical systems in order to perform their mission effectively. While today's shipboard systems are quite sophisticated, there are areas for improvement ...
Intent-aware collision avoidance for autonomous marine vehicles
(Massachusetts Institute of Technology, 2017)
Applications of autonomous marine vehicles in dynamic and uncertain environments continuously grow as research unveils new enabling technology and academic, commercial, and government entities pursue new marine autonomy ...
Examination of hull forms for an Offshore Nuclear Plant
(Massachusetts Institute of Technology, 2017)
The Nuclear Science and Engineering Department at MIT has a concept design for an Offshore Nuclear Plant (ONP). This project highlights the advantages of the offshore location by reducing the risk of natural disasters and ...
