Theses and Dissertations
AN INTEGRATED SIMULATION APPROACH FOR AUV IMAGE-BASED SLAM NAVIGATION
(Monterey, CA; Naval Postgraduate School, 2021-12)
This thesis develops a simulation framework for undersea feature-based navigation. Using an autonomous underwater vehicle (AUV) to locate an item of interest on the seafloor is a capability that would greatly benefit the ...
DESIGN, DEVELOPMENT, AND FLIGHT TESTING OF A MODULAR AVIONICS AND VEHICLE MONITORING SYSTEM
(Monterey, CA; Naval Postgraduate School, 2021-12)
As more rocket components become commercially available, the feasibility of a low-cost rocket-powered vehicle with capabilities tailored to the needs of the Navy, such as delivering payloads, countering drones, and reliable ...
STUDY OF COMPOSITE STRUCTURES SUBJECTED TO UNDERWATER SHOCK LOADING
(Monterey, CA; Naval Postgraduate School, 2021-12)
Underwater explosions (UNDEX) produce severe and complex loadings in naval applications. Increased use of composite materials in naval applications requires better understanding of how composite structures will respond and ...
EVALUATION OF A ROTATING PRINTER HEAD FOR ADDITIVE MANUFACTURING AT VARIABLE RESOLUTION
(Monterey, California. Naval Postgraduate School, 2021-06)
Nozzle-based additive manufacturing (AM) methods typically require a trade-off between print
resolution and mass deposition rates due to a set nozzle size. This requires longer build times for large,
highly detailed ...
ORIENTATION DEPENDENT MECHANICAL PROPERTIES OF 3D PRINTED POLYMER MATRIX COMPOSITES
(Monterey, CA; Naval Postgraduate School, 2021-06)
The use of composite materials for 3D printing is a promising area of study that is largely under-researched. Traditionally manufactured composites are known to have superior mechanical qualities, yet characteristics of ...
ADDITIVE MANUFACTURING OF PERSONALIZED WETSUITS
(Monterey, CA; Naval Postgraduate School, 2021-06)
Additive manufacturing (AM) provides opportunities to customize parts with precise control of geometry and materials. An application for the Navy is the fabrication of user-tailored wetsuits with superior fit, as well as ...
CORROSION BEHAVIOR OF COLD SPRAYED ALUMINUM OXIDE REINFORCED ALUMINUM COATINGS
(Monterey, CA; Naval Postgraduate School, 2021-06)
The selection of materials in the cold spraying process has a significant impact in corrosion resistance. Recognition of this could provide the opportunity to adapt a wide range of coating deposits for different applications ...
HYBRID INSPIRED TRIBOELECTRIC NANOGENERATOR USING CONTACT SEPARATION MODE
(Monterey, CA; Naval Postgraduate School, 2021-06)
The triboelectric nanogenerator (TENG) concept was used to build four contact separation TENG models to harvest mechanical vibration from an aircraft wing on an unmanned air and surface vehicle. The first three models used ...
ADDITIVE MANUFACTURING OF ALUMINUM ALLOY COMPONENTS SUITABLE FOR MARINE APPLICATION
(Monterey, CA; Naval Postgraduate School, 2021-06)
Additive manufacturing (AM) enables precise control of part shapes and can build geometries that cannot be conventionally produced. AM applications for the Navy include “print on demand” unmanned vessels or impact absorbers ...
COMPENSATION THROUGH PREDICTION FOR ATMOSPHERIC TURBULENCE EFFECTS ON TARGET IMAGING AND HIGH ENERGY LASER BEAM
(Monterey, CA; Naval Postgraduate School, 2021-06)
Atmospheric turbulence significantly degrades the performance of High Energy Laser (HEL) beams. The three key undesirable effects are: (1) degraded target images used for target tracking; (2) inaccurate HEL pointing; and ...
