Z-source circuit breakers in naval power systems
(Massachusetts Institute of Technology, 2019)
New power system components and control systems are required to facilitate the U.S. Navy's move to medium voltage direct current power (MVDC) systems on future vessels. Integrating the z-source circuit breaker into a ...
Naval additive manufacturing : bridging the gap between research and implementation
(Massachusetts Institute of Technology, 2019)
Additive manufacturing (AM), commonly known as three-dimensional printing, presents numerous advantages over traditional production methods, including design-to-end-use process reduction and on-demand generation of needed ...
New approaches to the integration of organizational maintenance and failure data during submarine maintenance planning
(Massachusetts Institute of Technology, 2019)
Planning for maintenance periods for U.S. Navy submarines is difficult due to schedule and cost constraints, operating cycles, and logistical concerns. Organizational maintenance and failure data is vital to understanding ...
Use of an asymmetric propeller for unmanned underwater vehicles
(Massachusetts Institute of Technology, 2019)
This thesis describes the development and execution of a test program to determine the suitability of an asymmetric propeller for unmanned underwater vehicles (UUV). The idea to utilize a single blade propeller had been ...
Resilient acquisition : unlocking high-velocity learning with model-based engineering to deliver capability to the fleet faster
(Massachusetts Institute of Technology, 2019)
As the nation's security needs call for a growing naval fleet, the public-private industrial base for construction and weapon system acquisition will be stressed to perform at a high level of operational excellence. While ...
Quantification of extreme event statistics in ship design
(Massachusetts Institute of Technology, 2019)
Increased operational demands on Navy vessels extend time at sea and service life, making the accurate prediction of catastrophic failures increasingly challenging. The high value of these capital assets puts great pressure ...
