David M. Van Wie, PhD, will present “Hypersonics: Back to the Future.”
Hypersonics is defined as flight at speeds above Mach 5—five times the local speed of sound. Currently, there is a resurgence of interest in hypersonic systems for applications such as weapons, rapid commercial transportation, and space launch. To realize these new applications, technology advancements are needed in the areas of novel thermal protection systems, high-temperature materials, advanced guidance, navigation and control, and propulsion. For more than 60 years, researchers at the Johns Hopkins University Applied Physics Laboratory have been investigating hypersonic technologies and applications, including Frederick S. Billig’s pioneering development of scramjet engine technology. Dr. Van Wie will offer a brief history of hypersonics highlighting Dr. Billig’s contributions and will discuss ongoing technology development challenges in this area.
HEMI research asks fascinating questions about what happens to materials under extreme conditions. Much of HEMI’s research can’t be perceived without powerful scanning technologies, let alone touched. Touch and perception, however, are both essential to how artists and designers learn and understand the world.
Symmetry and Fracture offers a way to physically connect with the complex research ideas of HEMI labs through hands-on exploration of mineral crystal systems and the grain boundaries of metallic materials.
You are invited to playfully investigate and decide for yourself where or if boundaries lie between art and science.
