William H. Mason Memorial Distinguished Lecture Series

Abstract: 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.

Abstract: NASA has a long history of serving the Nation and the world, by reaching for new heights and revealing the unknown for the benefit of all humankind. To ensure the agency will deliver on its mission in a hyper-connected, technology-enabled, globally-partnered, and rapidly-changing world, in 2020 NASA launched a Digital Transformation initiative to modernize the way it works, the experience of its workforce and the agility of its workplace.  Come hear how Hokies have shaped NASA’s digital strategy, the exciting progress being made, and lessons learned from their journey - and join the debate on how Virginia Tech can lead the way preparing the next generation to serve the world in a digital future.

Biography: Ms. Jill Marlowe is the Agency’s Digital Transformation Officer, and leads the Agency to conceive, architect, and accelerate enterprise digital solutions that transform NASA's work, workforce and workplace to achieve bolder missions faster and more affordably than ever before. In this role, she first defined and refines NASA’s digital transformation vision, strategy, and policies to accelerate NASA’s transformation progress focused on four targets: engineering, discovery, program/project management decision making, business operations. She partners with internal/external organizations to plan, coordinate and integrate implementation activities exercising five digital levers to accelerate progress: interoperable architectures, process transformation, maximizing data, common tools, inclusive teaming.

Prior to this role, Ms. Marlowe was the Associate Center Director, Technical, at NASA’s Langley Research Center in Hampton, Virginia. Ms. Marlowe led strategy and transformation of the center’s technical capabilities to assure NASA’s future mission success. In this role, she focused on accelerating Langley’s internal and external collaborations as well as the infusion of digital technologies critical for the center to thrive as a modern federal laboratory in an ever more digitally-enabled, hyper-connected, fast-paced, and globally-competitive world.

In 2008, Ms. Marlowe was selected to the Senior Executive Service as the Deputy Director for Engineering at NASA Langley, and went on to serve as the center’s Engineering Director and Research Director. With the increasing responsibility and scope of these roles, Ms. Marlowe has a broad range of leadership experiences that include: running large organizations of 500 - 1,000 people to deliver solutions to every one of NASA’s mission directorates; sustaining and morphing a diverse portfolio of technical capabilities spanning aerosciences, structures & materials, intelligent flight systems, space flight instruments, and entry descent & landing systems; assuring safe operation of over two-million square feet of laboratories and major facilities; architecting partnerships with universities, industry and other government agencies to leverage and advance NASA’s goals; project management of technology development and flight test experiments; and throughout all of this, incentivizing innovation in very different organizational cultures spanning foundational research, technology invention, flight design and development engineering, and operations. She began her NASA career in 1990 as a structural analyst developing numerous space flight instruments to characterize Earth’s atmosphere.

Ms. Marlowe’s formal education includes a Bachelor of Science degree in Aerospace and Ocean Engineering from Virginia Tech in 1988, a Master of Science in Mechanical Engineering from Rensselaer Polytechnic Institute in 1990, and a Degree of Engineer in Civil and Environmental Engineering at George Washington University in 1997. She serves on advisory boards for Virginia Tech’s Aerospace & Ocean Engineering Department, the Virginia Tech Center for Research in Aero/Hydrodynamic Technologies, Sandia National Laboratory’s Engineering Sciences Research Foundation, and Cox Communications Digitally Inclusive Communities (regional).

She lives in southeastern Virginia with her husband and the youngest of their three children and their energetic labradoodle.

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
