The optimization of a dual foil flapping device
(Monterey, California. Naval Postgraduate School, 2003-09)
Aquatic animals, such as dolphins and tuna, have the ability to swim and maneuver at much greater capacity than any man-made device. If their propulsion methods could be replicated mechanically, the benefits to underwater ...
Design and cold flow evaluation of a miniature Mach 4 Ramjet
(Monterey, California. Naval Postgraduate School, 2003-06)
Methods used for designing the ramjet included conic shock tables; isentropic flow tables and the GASTURB code was used for aerothermodynamic performance prediction. The flow field through the proposed geometry was computed ...
Incorporation of a Differential Global Positioning System (DPGS) in the control of an unmanned aerial vehicle (UAV) for precise navigation in the Local Tangent Plane (LTP)
(Monterey, California. Naval Postgraduate School, 1997-03)
The purpose of this thesis is to incorporate the Global Positioning System (UPS) and Inertial Navigation System (INS), for the guidance of an unmanned aerial vehicle (UAV) seeking precise navigation in a Local Tangent Plane ...
Composite failure criterion - probabilistic formulation and geometric interpretation.
(Monterey, California. Naval Postgraduate School, 1988-12)
The objective of this investigation is to derive the reliability and the associated probabilistic failure criterion for composite materials under combined stress. In the analytical derivation, the concept of joint ...
Flow visualization of the airwake around a model of a DD-963 class destroyer in a simulated atmospheric boundary layer
This study is part of a longer-term project to map the airwakes of model ships for scaling to full size and use in helicopter simulators to provide an alternative to at-sea dynamic interface testing utilizing the Naval ...
The age hardening response of thermomechanically processed Al-Mg-Li alloys
Four Al-Mg-Li alloys of compositions (weight percent) in the ranges of 6-8% Mg, 0.5-2% Li and 0.15-0.25% Zr were hot forged and warm rolled (thermo-mechanically processed) to achieve a microstructure suitable for ...
The effects of torque response and time delay on rotorcraft vertical axis handling qualities.
Research was conducted in support of updating the U. S. military handling qualities specification, MIL-H-8501A. The effects of torque response and time delay on rotorcraft vertical axis handling qualities were investigated ...
Effect of fiber diameter on the reliability of composites - Automated laser diffraction implementation
Composite failures are microscopically sequential and locally redundant. As a result, a composite structure reliability and its strength dependency on geometric size is intimately dependent on the statistics of fiber ...
Flow visualization of the airwake of an oscillating generic ship model
An experimental flow visualization study was done on an oscillating generic ship model in the Low Speed Wind Tunnel Facility at the Naval Postgraduate School in Monterey, California. The purpose was to visually analyze ...
On analysis of viscoelastic structures.
This study is to understand the effects of nonlinear behavior of structures using a finite element method. The nonlinear behavior equations are derived from equations of motion and constitutive equations. The basic theory ...
