Trailing Edge Flap Optimization for an Upper-Surface Blown Aircraft Wing

Creator:: Kelly, Bryan R.
Abstract:: Integrated Distributed Electric Augmented Lift (IDEAL) applies upper surface blowing in a novel way to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on propulsion airframe interaction (PAI) with trailing edge flaps at low Reynolds numbers was necessary to advance the...

A framework to model reliability and failures in complex systems during the early engineering design process

Creator:: O'Halloran, Bryan M.
Abstract:: An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...

Experimental study of impulse turbines and permanent magnet alternators for pico-hydropower generation

Creator:: Cobb, Bryan R.
Abstract:: Increasing access to modern forms of energy in developing countries is a crucial component to eliminating extreme poverty around the world. Pico-hydro schemes (less than 5-kW range) can provide environmentally sustainable electricity and mechanical power to rural communities, generally more cost-effectively than diesel/gasoline generators, wind turbines, or solar photovoltaic systems....

Vortex Generator Flow Control for an Upper-Surface Blown Aircraft Wing with an Extended Coanda Flap

Creator:: Kelly, Bryan R.
Abstract:: Integrated Distributed Electric Augmented Lift (IDEAL) applies upper-surface blowing in a novel way using an array of electric ducted fans (EDFs) to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on the use of vortex generators (VGs) to reduce flow separation...

Methodologies to improve reliability engineering in early design

Creator:: O'Halloran, Bryan M.
Abstract:: This thesis is the summation of two publications with the motivation to move reliability analysis earlier in the design process. Current analyses aim to improve reliability after components have been selected. Moving specific analyses earlier in the design process reduces the cost to the designer. These early design analyses provide...

Integrated Evaluation of Drinking Water Purification: A Mixed-Method Laboratory and Field Assessment of a Biomass-Powered Water Treatment Technology

Creator:: Burleson, Grace Ellen
Abstract:: The global water crisis is defined as one of the major threats facing humankind over the next decade with over 1 in 10 people lacking access to clean drinking water worldwide. An estimated 1.2 million people pasteurize their drinking water by using boiling as an indicator. Pasteurization is the process...

Development and Trial of a Usability Testing Protocol for Biomass Cookstoves : An Interdisciplinary Approach

Creator:: Moses, Nicholas D.
Abstract:: Improved cookstoves have been designed and disseminated for several decades in an effort to address the human health and environmental issues caused by the inefficient, traditional biomass cooking and heating methods used by 40% of the world’s people. Engineers and designers working on these improved stoves have tended to focus...

Identification of Physical and Chemical Processes on Ignition and Burning of Live Fuels

Creator:: Fazeli, Hamid
Abstract:: Wildland fire refers to an unpredictable and uncontrollable fire that happens in wildland areas. Regardless of the beneficial impacts of wildland fires on ecosystems, the destructive impacts of wildfires on air quality, economy, public health, etc. are considerable. An essential goal in the fire community is that the wildland fires...

Analytical method for the prediction of reliability and maintainability based life-cycle labor costs

Creator:: Fitzpatrick, Mark W.
Abstract:: An analytical method for predicting life-cycle maintainability labor costs is developed. The purpose of the analytical method is to allow the evaluation of products, based on life-cycle labor cost, early in the design process. The Boeing 737-300/400/500 Bleed Air Control System is used as a test model, and the results...

The energy extraction performance of an oscillating rigid and flexible foil

Creator:: Totpal, Alexander D.
Abstract:: The aerodynamic performance of an oscillating pitching and plunging foil operating in the energy harvesting mode is investigated. Experiments are conducted in a closed-loop recirculating wind tunnel at Reynolds numbers of 24,000 to 48,000, and reduced frequencies (k = fc/u) of 0.042 to 0.083. Foil kinematics are varied through the...
