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 ...
Semi-active structural control systems with nonlinear actuator dynamics: Design, stability analysis, and experimental verification.
(2001)
The dissertation presents the development and experimental validation of control laws that provide stable closed-loop behavior and good performance for semi-active control systems with nonlinear actuator dynamics. In ...
Effects of Equivalence Ratio and Iodine Number on NOx Emissions from the Flames of Biofuels and Hydrocarbons
(2009)
Increased energy consumption in the United States has led to a demand for the development of new bio-derived fuels. As biofuels are used more frequently in diesel and gasoline engines it has become increasingly important ...
A platform cascading method for scale based product family design.
(2007)
In this dissertation, a product family design method for scale based products leveraged from multiple platforms is presented. A product family is a set of related products derived from a product platform. Product family ...
Buoyancy effects on flow structure and instability of low-density gas jets.
(2004)
Linear temporal and spatio-temporal stability analyses of a low-density round gas jet injected into a high-density ambient gas were performed by assuming hyper-tan mean velocity and density profiles. The flow was assumed ...
Flow structure of low-density gas jets and gas jet diffusion flames.
(2006)
Buoyant jets and flames have been a subject of significant research in fluid dynamics. Such flows are influenced by near field instabilities, turbulence, buoyancy, chemistry, heat release, etc. The present research deals ...
DESIGN AND ANALYSIS OF ROVER WHEEL TESTBED
(2009)
Wheel performance has been one of the limiting factors in interplanetary rover mis-
Implementation of three-dimensional visualization in interactive Web-based environment for engineering education and technical training.
(2003)
The first system, the CSD System is not only an illustration environment, but also an actual system that has been built for Tinker Air Force Base (AFB). The main purpose of Tinker AFB having this web-based environment ...
Buoyancy-induced heat and mass transport in a porous medium near a buried pipe.
(2006)
The heat and mass transport in a porous medium induced by buoyancy from a buried heated pipe has been examined in this study. Due to the complexity and irregularity of geometry involved, body-fitted coordinate systems along ...
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 ...
