Event Type: discussion, led, by, professor, sharvan, kumar, brown, university
Organized By: Tilde Cafe/Deepti Pradhan
Latest Activity: Nov 12, 2010
The next cafe discussion is made possible with support from a grant from NOVA/WGBH. It is a lead-in to the upcoming four part PBS special relating to Materials Science - "Making Stuff: Stronger, Smaller, Smarter, Cleaner". Beginning January 19, 2011, NOVA will premiere this new four-hour series on consecutive Wednesday nights at 9 pm ET/PT on PBS (check local listings).
Professor Sharvan Kumar from the School of Engineering, Brown University, has generously agreed to come to Branford and tell us about Aircraft Engines: Yesterday, Today and Tomorrow. He has provided a brief outline for the afternoon:
"The desire to fly faster, fuel efficient and more comfortable/quieter aircrafts has placed an unprecedented demand on new materials for aircraft engines. Aircraft engines use a variety of materials for the different components within the engine, depending on whether they are rotating or static parts, and whether they are in the front or aft of the combustion chamber. Engine manufacturers have become incredibly innovative with engine design and material usage. To a significant extent, processing technology has played a key role in enabling these innovations and designs. However, the current materials used in the engine are operating at close to their melting temperatures and the quest for new materials that can operate the engine hotter has been underway and is one of the biggest technological challenges in Materials Science. In this discussion/presentation, I will highlight the anatomy of a jet engine, identify the parts we will focus on, and then outline some of the enabling technologies as we transition from the early engines through the current day engine, and the kind of thinking that is evolving from a Materials standpoint and design standpoint for the engines in the twenty-first century."
