HYDROGEN ENHANCED ATOMIC TRANSPORT: CREATING HARD TITANIUM/TITANIUM HYDRIDE BROWN BODIES AT AMBIENT PRESSURE AND TEMPERATURE GREATER THAN 650 DEGREES CENTIGRADE
(Monterey, CA; Naval Postgraduate School, 2020-06)
This thesis introduces a simple, low-temperature method called Hydrogen Enhanced Atomic Transport (HEAT) for creating metallic bonded brown bodies on the order of 40% bulk density in molds of designed shape from titanium ...
COMPUTATIONAL AERODYNAMIC ANALYSIS OF AIRFOILS FOR ENERGY-PRODUCING SAILING SHIPS
(Monterey, CA; Naval Postgraduate School, 2020-06)
The purpose of this research was to determine an airfoil configuration that produces the maximum amount of thrust on a sailboat that uses a turbine deployed in the water to collect energy. Three airfoil types were analyzed: ...
ANALYSIS OF WAVE-INDUCED FORCING ON A SUBMERGED BODY AT VARIOUS PITCH ANGLES
(Monterey, CA; Naval Postgraduate School, 2020-06)
This experiment aimed to quantify the effect of pitch angle on the linear and nonlinear wave-loading of a submerged, cylindrical body. The lower-frequency nonlinear loads that occur in a multi-component seaway were also ...
AIRCRAFT CYBER COMBAT SURVIVABILITY
(Monterey, CA; Naval Postgraduate School, 2020-06)
The aircraft combat survivability (ACS) design discipline has proven effective in producing survivable combat aircraft for over fifty years. Currently, the discipline only focuses on kinetic threats; however, an emerging ...
OXIDATION BEHAVIOR OF OXIDE PARTICULATE REINFORCED TITANIUM COMPOSITES FABRICATED BY SELECTIVE LASER MELTING
(Monterey, CA; Naval Postgraduate School, 2020-06)
This thesis project mixed additive manufacturing (AM) feedstock powders of Ti-6Al-4V with 1% and 3% by volume reinforcements of Al2O3 and Ta2O5. These powders were printed using the MAE selective laser melting (SLM) printer, ...
MODELING FLOW OVER 3-D WING SPOILERS FOR MODEL B-52
(Monterey, CA; Naval Postgraduate School, 2020-06)
Analyzation of flight vehicles using computational tools typically relies on a linear model of the aircraft control surfaces to calculate control derivatives and flight response. This information is used to inform the ...
LOW-COST, DISPOSABLE MEMS RADIATION DETECTORS USING GAMMA-SENSITIVE POLYMERS
(Monterey, CA; Naval Postgraduate School, 2020-06)
Micro-electrical mechanical systems (MEMS) radiation detectors can be used in a variety of fields, such as medicine, homeland security, and the nuclear power industry, and for a variety of applications, such as environmental ...
INLET MASS FLOW MODELING AND MEASUREMENT THROUGH A TRANSONIC AXIAL COMPRESSOR FAN
(Monterey, CA; Naval Postgraduate School, 2020-06)
This study investigated the creation of a 3-D computational fluid dynamics model of the Transonic Compressor Rig used for the testing of the Naval Postgraduate School Military Fan. This modeled rig conditions the flow into ...
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 ...
MEASUREMENT OF FRICTIONAL DRAG ON ALLIGATOR-SKIN-LIKE FEMTOSECOND SURFACE TREATMENTS
(Monterey, CA; Naval Postgraduate School, 2020-06)
This research sought to determine whether femtosecond laser surface processing (FLSP) is a viable alternative to anti-corrosive, hydrodynamic coatings. FLSP was applied to stainless steel plates to see its effect on ...
