Development of helicopter attitude axes controlled hover flight without pilot assistance and vehicle crashes.
(2007)
In this work, we show how to computerize a helicopter to fly attitude axes controlled hover flight without the assistance of a pilot and without ever crashing. We start by developing a helicopter research test bed system ...
A prototype computerized synthesis methodology for generic space access vehicle (SAV) conceptual design.
(2006)
This dissertation presents the development steps required towards a generic (configuration independent) hands-on flight vehicle conceptual design synthesis methodology. This process is developed such that it can be applied ...
Effects of elliptical burner geometry on partially premixed gas jet flames in quiescent surroundings.
(2005)
The 3:1 AR elliptical and circular burners produced similar carbon monoxide and nitric oxide emission indexes over the range of equivalence ratios of 0.55 to 4.0, for laminar flames. (Abstract shortened by UMI.)
High-fidelity modeling and impact footprint prediction for vehicle breakup analysis.
(2005)
Thus the main thrust of this study was to develop and verify the additional dynamics modeling and capabilities for the analysis tool with the objectives to (1) have the capability to predict impact point and footprint, (2) ...
Analysis and control of thermoelastic vibrations in plate structures.
(2001)
This work is concerned with the analysis and control of thermoelastic vibrations in rectangular plate structures using piezoelectric materials for the sensor(s) and actuator(s). Both isotropic and symmetrically laminated, ...
An experimental and numerical investigation on hydrogen-hydrocarbon composite fuel combustion.
(2000)
Experimental measurements and numerical predictions show that the local flame temperature increases with the increase of hydrogen content in the mixture; consequently the NO production increases in the flame. On the other ...
Multidisciplinary design optimization of a fighter aircraft with damage tolerance constraints and a probabilistic model of the fatigue environment.
(2001)
Damage tolerance analysis (DTA) was considered in the global design optimization of an aircraft wing structure. Residual strength and fatigue life requirements, based on the damage tolerance philosophy, were investigated ...
Buckling and flexural vibration of rectangular plates subjected to half sinusoidal load on two opposite edges.
(2004)
The problem of buckling of thin rectangular plates subjected to uniform and linearly varying in-plane load has been solved quite some time back beginning with the work of Bryan in 1890--91. Recently, Leissa and Kang obtained ...
