Maneuverability estimation of high-speed craft
(Monterey, California: Naval Postgraduate School, 2015-06)
This thesis focuses on the problem of predicting the maneuvering characteristic of high-speed craft. A mathematical model is derived based on equations by Lewandowski and Denny-Hubble in order to find the fundamental ...
Fabrication of a mechanically robust carbon nanofiber foam
(Monterey, California: Naval Postgraduate School, 2015-06)
In this thesis, the constrained formation of fibrous nanostructures process was scaled up to fabricate mechanically robust, homogenous foam samples. Scaling up this process required the design of a stainless steel mold ...
Increasing slew performance of reaction wheel attitude control systems
(Monterey, California: Naval Postgraduate School, 2013-09)
This thesis explores the physical and mathematical limitations of two common attitude control systems: one based on reaction wheels and another based on control moment gyroscopes (CMGs). The dynamics are derived from first ...
Standardizing methods for weapons accuracy and effectiveness evaluation
(Monterey, California: Naval Postgraduate School, 2014-06)
The Joint Technical Coordinating Group for Munitions Effectiveness desires a standardized toolbox and methodologies for evaluating weapons accuracy. Using statistical distributions, a method is presented for both unguided ...
Development of carbon nanotube-based sensor to monitor crack growth in cracked aluminum structures underneath composite patching
(Monterey, California: Naval Postgraduate School, 2014-06)
This paper presents the design of a carbon nanotube-based sensor to detect crack propagation in aluminum structures underneath composite patching. Initial tests are utilized to determine the correct procedure and materials ...
Fluid-structure interaction in a fluid-filled composite structure subjected to low velocity impact
(Monterey, California: Naval Postgraduate School, 2016-06)
The effects of fluid structure interaction in a fluid-filled cubic composite structure subjected to low velocity impact are the focus of this study. A fabrication technique was developed for creating an E-glass composite ...
Wing-embedded, cross-flow-fan, vertical takeoff and landing air vehicle
(Monterey, California: Naval Postgraduate School, 2016-06)
This research demonstrated that a vertical takeoff and landing aircraft capable of transitioning to conventional flight using cross-flow fans is possible. In particular, the design and manufacture of a wing-embedded ...
Energy-efficient underwater surveillance by means of hybrid aquacopters
(Monterey, California: Naval Postgraduate School, 2014-12)
This thesis develops algorithms in support of a prototype hybrid air-water quadcopter platform: the AquaQuad. We consider the scenario in which AquaQuads with underwater acoustic sensing capabilities are tracking a submerged ...
Automated maneuver design and checkout for the Lunar Reconnaissance Orbiter
(Monterey, California: Naval Postgraduate School, 2014-12)
The Lunar Reconnaissance Orbiter (LRO) is a lunar surface mapping and data collection mission launched by NASA in 2009. As a mapping and imaging mission, frequent attitude maneuvering is required. The LRO currently follows ...
Improving the performance of MEMS gyros via redundant measurements: theory and experiments
(Monterey, California: Naval Postgraduate School, 2014-12)
A redundant sensor array is a device composed of more than one sensor of a given type, for example an array of rate gyroscopes. Previous work has shown that redundancy can enhance the failure tolerance of the sensor suite ...
