Aerospace & Mechanical Engineering Seminar
January 26, 2012 at 5:00 PM - 6:00 PM
McDonnell Douglas Hall, Room 2101
The first AE/ME Graduate Seminar of the 2012 semester will be this Thursday, January 26 at 5pm in MDH 2101. Dr. Mitch Wolff of the Air Force Research Laboratory will present on his research in energy-optimized aircraft with a focus on gas turbines.
About the Seminar:
A new subsystem-based approach, INtegrated Vehicle and ENergy Technolog program (INVENT), to solve on demand aerospace vehicle energy management issues is being pursued by the Air Force Research Laboratory, Energy, Power and Thermal Division (AFRL/RZP). The goal of this approach is to create an “Energy Optimized Aircraft” that will maximize energy utilization for broad capabilities while minimizing complexity. On demand systems require attention to issues of system integration and energy management for optimal performance and capability. Integrated system modeling and simulation spans a broad range of technical expertise such as thermal management, power generation, power distribution and load management in a highly dynamic environment. Energy conversion is critical in the efficient design of on demand systems. For aircraft applications, the majority of energy conversion takes place in the gas turbine. Therefore, significant opportunities exist for optimizing this process especially consideration of auxiliary systems and how they interface with the hot gas engine sections. Gear boxes and starter/generators are key components of power generation leading to power distribution which is then connected to load management. Methods of storing and dissipating energy such as high-energy density batteries, super-capacitors and heat exchangers are also vital for on demand system optimization, which has regenerative energy capability. Underlying these system integration issues is the basic energy management issue of on demand highly dynamic thermal management. Finally from an experimental view, hardware in the loop (HIL) system integration optimization for energy management is being pursed. Initial results of recent in-house AFRL/RZP research will be present which is focused strongly on the development of high fidelity aircraft modeling and simulation capabilities.
About Dr. Wolff
Dr. Mitch Wolff received his B.S., M.S., and Ph.D. in Mechanical Engineering from Purdue University in 1983, 1989, and 1995, respectively. In the fall of 2008, he joined AFRL in an IPA position as the Scientific Advisor for INVENT. He will continue in this position until the fall of 2012 when he will rejoin Wright State University. He joined the Wright State faculty in September 1995 as an assistant professor of mechanical engineering being promoted to associate professor in September 2000 and professor in September of 2003.
He is the co-author of over 100 technical papers and journal articles in the areas of propulsion, computational methods, hardware in- the-loop, system integration, unsteady aerodynamics, forced response, and high speed flows. Dr. Wolff has participated in the AFOSR summer faculty program as a visiting scientist with the Aero Propulsion & Power Directorate, Compressor Aero Research Laboratory (1996, 1997), and the Air Vehicles Directorate (1998), Wright-Patterson Air Force Base. In 1999, Dr. Wolff was recognized with the SAE Ralph R. Teetor Educational Award, the ASEE Dow Outstanding New Educator Award, and the College of Engineering and Computer Science Teaching Effectiveness Award. He received in 2001 the College of Engineering and Computer Science Outstanding Faculty Award.
In 2003, he was selected by the Affiliate Societies Council of Dayton for the Outstanding Engineers & Scientists Award in Education. Dr. Wolff served on a National Research Council Review Panel of NASA’s Aeronautics Research Programs in 2003. He was a Visiting Professor in 2004 at the Laboratory of Applied Thermodynamics & Turbomachinery at the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland. Dr. Wolff is a member of ASEE, SAE, an associate fellow of AIAA, and a fellow of ASME.
