Unsteady flow field measurements using LDV.
The primary goal of this thesis was the development of an experimental technique, and supporting software, for the acquisition and analysis of unsteady velocity data generated by an oscillating airfoil. This research was ...
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 ...
High Reynolds number
A Navier-Stokes code, developed by N.L. Sankar, and an Interactive Boundary Layer code, developed by Tuncer Cebeci, are implemented for high Reynolds number, low Mach flows over a NACA 0012 airfoil. Upper surface pressure ...
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 ...
Optimizing HF antenna systems on the Dolphin and Sea Hawk helicopters
Making an aircraft available and modifying it to test various antenna systems and configurations is extremely costly. The computer model is an excellent alternative means of analyzing antenna systems for optimum communication ...
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 ...
Experimental design of a piloted helicopter off-axis-tracking simulation using a helmet mounted display.
The development of target tracking weaponry on the Army's Advanced Attack Helicopter (AAH) allows directional tracking with FLIR imagery at large angles from the longitudinal axis. A flight simulation using a helmet mounted ...
Flow field measurements using hotwire anemometry
A computer controlled data acquisition system utilizing hotwire anemometry has been designed, built and installed in the Naval Postgraduate School Low Speed Wind Tunnel Facility. All relevant wind tunnel data is obtained ...
