William H. Mason Memorial Distinguished Lecture Series
2024 LECTURE
Dr. Dimitri Mavris, Distinguished Regents Professor, School of Aerospace Engineering and Director, Aerospace Systems Design Laboratory, Georgia Institute of Technology, "Environmental Assessment of Novel Aircraft Configurations and Technologies"
Hosted on October 15, 2024 3:30 PM in MCB 129
During the 40th Session of the Assembly of the International Civil Aviation Organization (ICAO), the Member States requested a feasibility assessment of a long-term global aspirational goal (LTAG) for international civil aviation in three sectors: technology, fuels, and operations. ICAO’s Committee on Aviation Environmental Protection (CAEP) organized a Technology Sub-group to better understand future evolutionary technologies for airframes, propulsion systems, and advanced concepts (including energy storage) up to 2050. Scenarios were analyzed to understand the impacts on CO2 emissions, costs, and investments, as well as potential implications on aviation growth, noise, and air quality. Professor Dimitri served as co-chair of the Technology Sub-group and under his direction the Aerospace Systems Design Laboratory conducted research in support of this study.
In this presentation, Professor Mavris will provide the technological perspective of LTAG with a high-level overview of the integrated results. The LTAG methodology involved three main steps including creating the technology reference aircraft, assessment of advanced tube and wing configurations, and assessment of advanced concept aircraft. A detailed methodology was developed and the international community was engaged to determine the potential of airframe and propulsion technologies possible up to 2050. Advanced tube and wing aircraft have a clear potential to improve the fuel (energy) efficiency of the international aviation system with some incremental contribution from aircraft with unconventional configurations, within the time frame considered for the study. While the integrated scenarios (technology, fuels, and operations) show the potential for substantial CO2 reduction, none of the scenarios reach zero CO2 emissions by 2050, but a carbon neutral growth could be achieved.
Dimitri Mavris earned his B.S. (1984), M.S. (1985), and Ph.D. (1988) in Aerospace Engineering from Georgia Tech. He is the Boeing Chaired Professor of Advanced Aerospace Systems Analysis in Georgia Tech’s School of Aerospace Engineering, Distinguished Regents Professor, and an S.P.

2022: Dr. Daniel Miller, Lockheed Martin, "Sunset or Sunrise? A Skunk Works Take on Flow Control for Tomorrow's Air Vehicles"
Abstract: Tomorrow's air vehicles will need higher degrees of platform functionality, performance, and integration of enabling advanced subsystems than those in service today. New platforms will most likely be unconventional configurations as well. This lecture will provide an overview of promising emergent flow control technologies in this context as well as the prospects of new technologies buying their way onboard an aircraft. Active flow control has emerged as one of the technologies that could improve aircraft performance by removing jointed surfaces which increase weight and mechanical complexity. Here is a link to a one-minute YouTube video which offers an intriguing glimpse of the promise of this technology: https:// www.youtube.com/watch?v=ruSQa1PvC3E&t=4s

About the Lecture Series
The William H. Mason Memorial Distinguished Lecture is sponsored by the Kevin T. Crofton Department of Aerospace and Ocean Engineering in memory of Dr. Bill Mason, a dedicated educator at Virginia Tech from 1989 until his passing in 2019. He was a lifelong Hokie, having earned his bachelor’s degree in 1971, a master’s degree in 1972, and a doctoral degree in 1975, all in aerospace engineering at Virginia Tech.
Dr. Mason was deeply passionate about airplanes. As a teenager, he spent countless hours building and flying model airplanes. As an undergraduate student at VT, he gained practical experience during summers working at McDonnell Douglas in St. Louis, Missouri, on various F-4 aircraft projects including the ‘swing wing’ F-4, and at the Edwards Air Force Base, California, on the U.S. Army Huey Cobra helicopters.
In 1974, he began his professional career with Grumman in Long Island, New York. Over the next 15 years, he made highly valuable contributions to many high-profile projects. Examples include (i) the X-29, an experimental aircraft with a forward-swept wing and canard; (ii) the NASA/Grumman Research Fighter Configuration with supercruise and maneuvering capabilities; and (iii) the SC3 Wing Concept which set a record for low drag at high-lift supersonic performance.
Dr. Mason returned to VT in 1989 and immediately devoted himself to sharing his knowledge with undergraduate and graduate students, his colleagues, and student design teams. He taught courses in aircraft design; applied computational aerodynamics; and configuration aerodynamics while performing research in aerospace systems design; multidisciplinary optimization; and applied aerodynamics. His legacy lives on with a large number of students he educated and advised by generously sharing his unique insights in aerodynamics and hydrodynamics. He co-authored Applied Computational Aerodynamics: A Modern Engineering Approachone of the first textbooks in the world on this subject for undergraduates. In addition, he also authored an unpublished manuscript of Configuration Aerodynamics textbook, and authored or co-authored more than 100 technical papers and reports.
A consummate professional and an unpretentious man, he combined his love of aircraft and vast knowledge and experience of design and configuration aerodynamics in extraordinary ways to make a lasting difference.
Virginia Tech honors Dr. Mason’s legacy and contributions by hosting an annual lecture in fall on topics related to aerospace and ocean vehicle systems design including multidisciplinary optimization, applied fluid dynamics, and aerospace engineering education.
