Design and testing of an autonomous mothership for surface vehicle swarm docking
(Massachusetts Institute of Technology, 2019)
The field of marine autonomous systems has blossomed over the past several decades yet much remains to be explored. One important focus area gaining increased attention in this domain is the understanding and development ...
Design and construction of a propeller open water testing apparatus and testing of a stereolithography 3D printed model propeller
(Massachusetts Institute of Technology, 2019)
This thesis describes the design and construction of a propeller open water testing apparatus for educational and experimental use at MIT. This test apparatus was built as an inexpensive alternative to conducted in-house ...
Simulation-guided lattice geometry optimization of a lightweight metal marine propeller for additive manufacturing
(Massachusetts Institute of Technology, 2019)
Additive manufacturing (AM) is one of the most promising emerging technologies for advanced mechanical systems. When compared to conventional manufacturing processes, AM offers major advantages in production of complex ...
Risk based decision making for the deferment of U.S. Navy submarine maintenance
(Massachusetts Institute of Technology, 2019)
Maintenance of United States Navy submarines is a complex set of operations comprised of scheduling, budgeting, and executing a continuous stream of work across multiple vessels in the same maintenance facility year after ...
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 ...
Biomimetic improvement of the maneuvering qualities of unmanned underwater vehicles
(Massachusetts Institute of Technology, 2019)
In recent years, biomimetics has been used as a source of inspiration to improve the performance of engineered systems in several disciplines. In this thesis, we emulate the function of the retractable dorsal fins in tunas ...
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 ...
A launch and recovery system for integrating unmanned ocean vehicles onto surface platforms
(Massachusetts Institute of Technology, 2019)
Unmanned vehicles (UxVs) are becoming more prevalent across all domains. As UxV technology improves and their operations become more essential to mission success, the challenge of integrating these vehicles onto current ...
