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 human interface with one atmosphere diving suit by appendages
(Massachusetts Institute of Technology, 2016)
This experimental study of the human interface with an Atmospheric Diving Suit (ADS) develops a method for quantitatively evaluating how the pilot interacts with the suit's appendages to inform design improvements and to ...
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 ...
Modeling brake specific fuel consumption to support exploration of doubly fed electric machines in naval engineering applications
(Massachusetts Institute of Technology, 2016)
The dynamic operational nature of naval power and propulsion requires Ship Design and Program Managers to design and select prime movers using a much more complex speed profile rather than typical of commercial vessels. ...
Multi-attribute tradespace exploration for US Navy surface ship survivability: a framework for balancing capability, survivability, and affordability
(Massachusetts Institute of Technology, 2016)
In a political environment of austerity, the importance of understanding the design tradeoffs for new naval ship concept designs cannot be understated. A combination of a tightened shipbuilding budget, large high-priority ...
Design and testing of a pan-tilt mechanism for severe environments
(Massachusetts Institute of Technology, 2016)
U.S. Navy ships have non-rotating radar and electronic warfare devices installed, which are often supported and trained by two-axis gimbals. In current shipboard solutions the payloads are often placed on a platform above ...
Automation as a manpower reduction strategy in navy ships
(Massachusetts Institute of Technology, 2016)
Since the early 2000's, the US Navy has endeavored to decrease the Total Ownership Cost (TOC) of their ships through a decrease in Operating and Support costs. This led to a large-scale effort by ship program managers to ...
Using the principles of set-based design to realize ship design process improvement
(Massachusetts Institute of Technology, 2016)
Set-based design (SBD) is a relatively new complex product development method. Its use has been well researched in the automotive and aerospace industries and, although it requires an upfront investment in resources, it ...
Object localization and identification for autonomous operation of surface marine vehicles
(Massachusetts Institute of Technology, 2016)
A method for autonomous navigation of surface marine vehicles is developed A camera video stream is utilized as input to achieve object localization and identification by application of state-of-the-art Machine Learning ...
Bragg reflector geometries for colorimetric orientation and deformation sensing
(Massachusetts Institute of Technology, 2016)
Propulsion systems of commercial and naval ships are typically large and expensive. They must be kept well-aligned and free of corrosion to efficiently and reliably transfer torque to a ship's propeller. Early identification ...
