Challenges and opportunities for Hypersonic Flight

by

Dr. Mark J. Lewis

Honorary Fellow of the American Institute of Aeronautics and Astronautics

Executive Director, Emerging Technologies Institute

Hypersonic flight is a very exciting and fast-developing aerospace field. Please join us and learn more from the leading top expert and the AIAA Honorary Fellow, Dr. Mark Lewis!

Dr. Mark J. Lewis

Honorary Fellow of the American Institute of Aeronautics and Astronautics,

Executive Director, Emerging Technologies Institute

Dr. Mark J. Lewis is the Executive Director of the National Defense Industrial Association’s Emerging Technologies Institute (ETI), a non-partisan research center focused on technologies that are critical to the future of national defense. ETI provides research and analyses to inform the development and integration of emerging technologies into the defense industrial base.

Prior to this position, Dr. Lewis was the Director of Defense Research & Engineering in the Department of Defense (DoD), overseeing technology modernization for all Services and DoD Agencies, as well as the acting Deputy Under Secretary of Defense for Research & Engineering. In that role, he was the Pentagon’s senior-most scientist, overseeing an organization with a $17B annual budget that includes DARPA, the Missile Defense Agency, the Defense Innovation Unit, the Space Development Agency, Federally Funded Research and Development Centers (FFRDC), and the Department’s basic and applied research portfolio.

From 2012 to 2019, Dr. Lewis was the Director of the Science and Technology Policy Institute, an FFRDC that supported the Executive Office of the President and other Executive Branch agencies in the formulation of national science and technology policy. Dr. Lewis is a professor emeritus at the University of Maryland, where he served as the Willis Young, Jr., Professor and Chair of the Department of Aerospace Engineering until 2012. A faculty member at Maryland for 25 years, Dr. Lewis taught and conducted basic and applied research in the fields of hypersonic aerodynamics, advanced propulsion, and space vehicle design and optimization. Best known for his work in hypersonics, Dr. Lewis’s research has spanned the aerospace flight spectrum from the analysis of conventional jet engines to entry into planetary atmospheres. From 2004 to 2008, Dr. Lewis was the Chief Scientist of the U.S. Air Force, the principal scientific adviser to the Chief of Staff and Secretary of the Air Force. As the longest-serving Chief Scientist in Air Force history, his primary focus included hypersonics, space launch, energy, sustainment, advanced propulsion, basic research, and workforce development. From 2010 to 2011, he was President of the American Institute of Aeronautics and Astronautics, the world’s premiere aerospace professional society

Dr. Lewis attended the Massachusetts Institute of Technology, where he received his Bachelor of Science in Aeronautics and Astronautics, Bachelor of Science in Earth and Planetary Science (1984), and Master of Science (1985) and Doctor of Science (1988) in Aeronautics and Astronautics. He is the author of more than 340 publications and has been an adviser to more than 70 graduate students. In addition, he has served on various boards for NASA and the DoD, including two terms on the Air Force Scientific Advisory Board.

A recipient of the USAF Exemplary, Meritorious, and Exceptional Civilian Service Awards, and of the Secretary of Defense Outstanding Public Service Award, Dr. Lewis was also the 1994 AIAA National Capital Young Scientist/Engineer of the Year; received the IECEC/AIAA Lifetime Achievement Award, the AIAA Dryden Lectureship Award, and the AFA Theodore von Karman Award; and is an Aviation Week and Space Technology Laureate. He is a member of the International Academy of Astronautics, a Fellow of the American Society of Mechanical Engineers, a Fellow of the Royal Aeronautical Society, and an Honorary Fellow of the American Institute of Aeronautics and Astronautics.

Addressing the Challenges of the Design of Hypersonic Vehicles with Simulation

More recently, the United States Department of Defense (DoD) has been actively pursuing and supporting the development of hypersonic weapons and vehicles owing to the continued threat from adversaries. The Pentagon’s FY2021 budget request for all hypersonic related research is at $3.2B – up from $2.6B in FY2020. Hypersonic vehicles fly at speeds of at least Mach 5, which is five times the speed of sound in air. These extreme operational conditions pose unique challenges in the design, manufacturing, and sustainment of these vehicles. Also, the lifetime of these defense vehicles and weapons span over decades.

Some of the major challenges in the design of hypersonic vehicles are in the areas of aerothermodynamics, propulsion, structures and materials, thermal management, and phenomena such as communication blackout and aero-optical effects. This presentation will focus on how Ansys physics-based simulation technologies can help the designers and analysts address these challenges in the context of hypersonic vehicle design. Simulation can provide a framework for validation of these designs, reduce the need for physical tests resulting in cost savings and compressed design cycle time.

Parsons Digital Engineering Framework (PDEF) Hypersonic Demonstration
This talk presents a demonstration of digital systems engineering at a System of Systems level. The focus is on the deployment of various sensor platforms to provide tracking opportunities for various hypersonic trajectories. Requirements are generated based on high level system performance and how the overall laydown contributes to the maximum viewing time allowed for the system of systems. The talk outlines the process of generating a threat vignette and using that to develop requirements based on system performance. The laydown consists of fixed and mobile sensor platforms and an optimization study is performed to determine the best placement of mobile sensors within operational areas. In addition, a probabilistic analysis is performed to calculate the most likely position within 3 sigma around each optimized mobile sensor location. These values are used to determine threshold and goal key performance parameters that can be used in trade studies to see the effects of modifying the sensor parameters and ensuring that requirements are still being met.
This talk also presents a digital framework that was used to create the workflow and integrate various simulations tools such as STK and MATLAB into the process. The framework consists of a Model Based Systems Engineering tool, No Magic’s Cameo; a integration tool and simulation execution engine, Phoenix Model Center, and performance models developed in Systems Tool Kit and MATLAB. Outputs from these studies are configuration managed in a SQL database and performance metrics can be view through a Digital Dashboard, such as Microsoft’s PowerBI tool. Finally, all simulations are ran in a virtual environment hosted in Microsoft Azure.
