Acoustic emission from spectrum fatigue cracks in 7075 aluminum
The E-2C Hawkeye, a U.S. Navy aircraft, has experienced problems with fatigue cracks in its wings. This problem was studied in the laboratory using a representative specimen under simulated flight loading. Acoustic emission ...
Analysis of a perturbation solution of the main problem in artificial satellite theory
(Monterey, California: Naval Postgraduate School, 1990-09)
The development of a universal solution of the main problem in artificial satellite theory has only recently been accomplished with the aid of high powered computers. The solution to this long standing problem is an ...
Numerical studies of compressible flow over a double-delta wing at high angle of attack
(Monterey, California. Naval Postgraduate School, 1990-03)
The objective of this work is the investigation of vortical flows at high angles of attack using numerical techniques. The first step for a successful application of a numerical technique, such as fimite difference or ...
The effects of nozzle geometry on particle size distribution in a small two dimensional rocket motor
(Monterey, California. Naval Postgraduate School, 1989-09)
Laser diffraction particle sizing was conducted at the nozzle entrance, inside the nozzle, and in the exhaust plume of a small two-dimensional rocket motor using two different metallized propellants to determine the effects ...
The use of a microcomputer system as an aid to classical and digital control system design and analysis.
(Monterey, California. Naval Postgraduate School, 1983)
This thesis takes five FORTRAN IV programs from "Computer Programs for Computational Assistance in the Study of Linear Control Theory" by Melsa and Jones and translates them into a microcomputer BASIC language to run ...
Finite element program for calculating flows in turbomachines with results for NASA Task-1 compressor
(Monterey, California. Naval Postgraduate School, 1982-10)
A general mesh generation code (MESHGEN) and finite element flow solver (TURBO) for calculating the flow development through axial turbomachines are fully documented. The finite element approach followed Hirsch and Warzee. ...
Automatic control and data acquisition system for combustion laboratory applications.
(Monterey, California. Naval Postgraduate School, 1982)
A modern computer based automatic data acquisition/control system was installed at the Department of Aeronautics' Combustion Laboratory. This system utilizes an HP-85 desktop computer as system controller for the HP-3054A ...
A study of state rate feedback implicit model following control for VSTOL aircraft.
(Monterey, California. Naval Postgraduate School, 1980-09)
The State Rate Feedback Implicit Model Follower control concept is examined in detail from a classical and modern control theory viewpoint. State Rate Feedback Implicit Model Following (SRFIMF) is a concept whereby control ...
Estimation of sonobuoy position relative to an aircraft using extended kalman filters.
(Monterey, California. Naval Postgraduate School, 1979-09)
In airborne anti-submarine warfare there is a need to more accurately determine the positions of sonobuoys on the surface of the vater. This report develops two algorithms which employ extended Kalman filters to determine ...
Unsteady surface pressure and near-wake hot-wire measurements of a circulation control airfoil.
(Monterey, California. Naval Postgraduate School, 1977-09)
The large lift coefficient changes attainable with Circulation Control Airfoils through small changes in boundary layer blowing suggest rotary wing cyclic control can be obtained through modulation of the blowing. ...
