Computer program for the kinetics and populations in a xenon fluoride laser
(Monterey, California. Naval Postgraduate School, 1979-12)
To highlight in a qualitative manner the kinetics of an excimer laser, a simple computer model for calculating the species populations in a KrF laser cavity is developed; subsequently a computer program originally developed ...
Calculation of the oxide growth rate of 2-1/4 Cr - 1 Mo steel in air and the subsequent measurement of the strain required to crack the oxide
(Monterey, California; Naval Postgraduate School, 1980-09)
This study examined the growth rate of 2-1/4 Cr - 1 Mo steel in air under isothermal growth conditions. Two oxidizing temperatures were used, 403 degrees and 499 degrees, for five specimens each with oxidizing times varying ...
Application of H infinity method to modern fighter configuration
(Monterey, California. Naval Postgraduate School, 1989-12)
H„ optimal control theory, based on singular value loop shaping, is used to
synthesize a controller for the statically unstable longitudinal dynamics of X-29
aircraft. Two design cases are studied: 2-input 2-output; and ...
The computer simulation and modeling of a flexible missile in 2-D motion.
(Monterey, California. Naval Postgraduate School, 1989)
The development and computer simulation is presented for a bending flexible missile with a rigid-body controller system moving in a 2-D coordinate frame. In this thesis, the dynamic model was developed through the Equivalent ...
Development of a constituitive equation for HSLA-100 at cryogenic temperatures
(1987-12)
HSLA-100 is a 100ksi nominal yield strength steel being developed by the Navy for
Naval shipbuilding applications. To assist in ductile and brittle failure modelling of this low
carbon steel, tensile tests were conducted ...
Effect of chromium addition to the low temperature hot corrosion resistence of platinum modified aluminide coatings.
(1985)
Marine gas turbines face many adverse conditions such as
reduced fuel quality and a salt environment which present
the sulfur, chloride, and sulfates required to initiate and
propagate hot corrosion. A particularly ...
Plastic instability of aluminide and platinum modified diffusion coatings during 1100˚C cyclic testing.
(1985-12)
Platinum modified and unmodified aluminide diffusion
coatings, on a nickel base superalloy (IN-738), were
prepared to test the pre-aluminizing surface roughness
effect on coating oxide scale adherence. A preliminary
study ...
Computer simulation of random and non-random second-phase distributions in two-phase materials
(Monterey, California: Naval Postgraduate School, 1990-12)
The mechanical properties of any material with a discontinuous second phase dispersed in a matrix are recognized to be influenced by the distribution of the second-phase particles. Current models for the prediction of ...
The influence of thermomechanical processing on the elevated temperature mechanical behavior of 6061 aluminum - alumina metal matrix composite materials
(Monterey, California: Naval Postgraduate School, 1990-12)
A cast, aluminum-based discontinuous metal matrix composite was thermomechanically processed. The material studied was 6061 aluminum containing 10 vol. pct. or 15 vol. pct. alumina (Al2O3) particles, fabricated by casting ...
Experimental studies of impulse noise produced by spheres moving through water
(Monterey, California; Naval Postgraduate School, 1980-03)
It is known from previous experiments that freely falling spheres produce sudden noise bursts. The source of this noise is unknown and little is known about the conditions under which it occurs, In an attempt to study ...
