Theses and Dissertations
Optimal artificial boundary condition configurations for sensitivity-based model updating and damage detection
(Monterey, California. Naval Postgraduate School, 2010-09)
Frequently, in structural system identification (model updating or damage detection), the available set of data is incomplete, both spatially and in modal content. This incompleteness leads to the solution of underdetermined ...
Cost benefit analysis of the installation of a wind turbine on a naval ship
(Monterey, California. Naval Postgraduate School, 2010-09)
In order to reduce environmental pollution, reduce dependability from foreign energy sources, and avoid the uncertainty associated with an unpredictable rise in the price of oil, the use of alternative forms of energy is ...
Warship combat system selection methodology based on discrete event simulation
(Monterey, California. Naval Postgraduate School, 2010-09)
This thesis presents the development of a methodology for the conceptual design of a medium tonnage warship?s combat system for the Colombian Navy. The methodology is oriented toward the optimization of the operational ...
Experimental investigation of an oscillating flow generator
(Monterey, California. Naval Postgraduate School, 2010-03)
The objective of this project was to construct and test a device that can transform fluid flow into the continuous oscillatory linear motion of a hydro/airfoil. This device may be used to generate power from a renewable ...
Dynamic fluidic nozzles for pulse detonation engine applications
(Monterey, California. Naval Postgraduate School, 2010-03)
An efficient nozzle design is critical for enhancing the benefits of Pulse Detonation Engines (PDEs) and enabling
their use as future propulsion or power generation systems. Due to the inherent variation in chamber pressure ...
Improving the NPSCUL structure optimizing the mass
(Monterey, California. Naval Postgraduate School, 2010-09)
This thesis presents the mass optimization of the Naval Postgraduate School Cube Satellite Launcher. The current structure weights 170.63 lbs and can hold up to 24 Cube Satellites. The weight of the whole system, which ...
Dynamic failure of sandwich beams with fluid-structure interaction under impact loading
(Monterey, California. Naval Postgraduate School, 2010-12)
The objective of this research is to examine the added mass effect that water has on the dynamic response of a sandwich composite under impact, particularly impact leading to failure. Because sandwich composites are much ...
Aerodynamic validation of emerging projectile and missile configurations
(Monterey, California. Naval Postgraduate School, 2010-12)
The M549 projectile has been analyzed using two different aerodynamic codes. The semi-empirical AP05 code has provided a very fast way to obtain results. The CFX code, based on the numerical solution of the full Navier-Stokes ...
Numerical and experimental investigation of performance improvements of a cross-flow fan
(Monterey, California. Naval Postgraduate School, 2010-06)
The cross-flow fan has an inherent ability to provide thrust to an airfoil as well as provide boundary layer control. The thrust can be easily vectored and usually the cross-flow fan is fully embedded within the airfoil, ...
Detonation diffraction in a multi-step channel
(Monterey, California. Naval Postgraduate School, 2010-12)
This research investigated multiple detonation diffraction events in order to better understand the limits and benefits of diffraction strategies with respect to pulse detonation engine design. Hydrogen/air detonations ...
