This seminar presents the past, present and future of aviation, with chronological coverage of (i) propeller planes (involving fans, as used in World War II for flying over the Himalayas), (ii) jet planes (subsonic, involving combustion engines that use air to feed the combustion, including Stealth aircraft), (iii) supersonic aircraft (Concorde, 1969-2003, planned for revived commercial use), (iv) hypersonic aircraft (involving combustion engines that use solid fuel rather than air to feed the combustion due to thin air in the high altitude, used for the 1969 Moon landing and the Space Shuttle of 1981-2011, planned for commercial use), and (v) all-electric vertical take-off and landing aircraft (with no combustion engine, being developed for use as air taxi within a city). This talk also covers the current problems with aviation, as resulting from hail strike, bird strike, corrosion, joint degradation, flutter, vibrations, lightning and icing. These problems have resulted in numerous accidents and are alleviated by techniques including damage monitoring (either using embedded sensors or using the structural material as the sensor), lightning protection, vibration damping, electrical deicing, and automatic control (smart aircraft). This lecture was first presented for the general public in the International Women’s Air and Space Museum in Cleveland, Ohio, on Oct. 8, 2022.
Professor Chung received her PhD degree in Materials Science from Massachusetts Institute of Technology and her BS degree from California Institute of Technology. She is a pioneer and international leader in research on multifunctional structural materials. She has authored or coauthored over 600 peer-reviewed journal papers, and 10 books, with over 41,673 citations (Google Scholar). She is ranked by the 2022 Stanford University study (based on publications and citations) to be 13th among 315,721 materials researchers worldwide (living/deceased), and 1st among all researchers in UB (all disciplines combined, living/deceased). Chung is Fellow of ASM International and American Carbon Society. She received the Pettinos Award (an international research award) from the American Carbon Society, and an Honorary Doctorate Degree from University of Alicante, Spain. http://en.wikipedia.org/wiki/Deborah_Chung
