Talk Title: Harness Natural Wisdom to Design 3D-Printed Bionic Materials
Abstract: Living creatures are continuous sources of inspiration for designing synthetic materials. However,
living creatures are typically different from synthetic materials in two aspects: First, living creatures typically
feature sophisticated microstructures and architectures that are challenging to reproduce in traditional
engineering practice. Second, living creatures consist of living cells to support their metabolisms, such as
growth, regeneration, and remodeling, which are typically impossible in traditional synthetic materials. In this
talk, by harnessing modern additive manufacturing technologies, dynamic chemistry, and/or living organisms,
we report a series of 3D-printed bionic materials to imitate both architectures and metabolisms of living
creatures. For example, with the aid of dynamic chemistry, 3D-printed lightweight structures can self-heal
large-scale impact damages and fractures. With the aid of living bacteria, 3D-printed polymers can self-grow
into structural composites with pre-designed microstructures. With the aid of living plant cells, 3D-printed
artificial trees can harness photosynthesis to self-remodel into multifunctional materials.
Biography: Qiming Wang is an Assistant Professor in the Department of Civil and
Environmental Engineering of the University of Southern California. Prior to this
position, he received a Postdoc training at Massachusetts Institute of Technology
(2014-2015) and earned his Ph.D. degree at Duke University (2014). His research
interest is centered around additive manufacturing and mechanics of unprecedented
materials and structures that can potentially address grand engineering challenges,
including infrastructure, water, environment, robotics, and healthcare. His research
has been widely reported by prestigious media, such as Science News, Nature News,
Discovery, Washington Post, NBC News, Wall Street Journal, Physics Today,
Materials Today, and NASA Tech Briefs. He received a number of academic awards,
including NSF CAREER (2020), SME Outstanding Young Manufacturing Engineer
(2020), AFOSR YIP (2018), MRS Graduate Student Award (2014), ACS Arthur K.
Doolittle Award, Duke Kewaunee Student Achievement Award (2013), Duke Lew Pre-doctoral Fellowship
(2012), and ASME Best Paper Award (2011). He was elected as the Editor (2018) of ASME Technical
Committee of Mechanics of Soft Materials and become Secretary in 2019, Vice-chair in 2020, and Chair in
2021.

Speaker: Andrew Dorsey, USC AME PhD Student
Talk Title: Design Space Exploration of Future Open Rotors
Abstract: The goal of this paper is to determine whether an open rotor aircraft configuration has the potential to provide fuel-burn benefits relative to a conventional turbofan aircraft, and if so in which regions of the payload range design space adopting an open rotor technology would be most advantageous. A design space exploration focused on the major trends and design drivers is carried out for open rotor aircraft with aft mounted and wing mounted engines, and their performance compared to a turbofan baseline. We consider transport aircraft with ranges between 1000 and 7000 nautical miles and 50 to 400 passengers, and introduce a modeling approach for open rotor engines into a conceptual design and optimization framework. For each range-passenger requirement, aircraft are optimized for minimum fuel burn on an economic range mission. It is found that open rotor configurations are best suited for short range missions with large passenger counts, and that aft mounted open rotors outperfor
m wing mounted ones. The optimum open rotor engine design sacrifices engine and aerodynamic efficiency in order to limit integration penalties and propulsion system weight.
Biography: Andrew Dorsey is a PhD student under Professor Uranga. His research focuses on conceptual aircraft design, aircraft optimization, and exploring future aircraft technologies. Andrew works full time in the Advanced Concepts group of Boeing Commercial Airplanes as a conceptual aircraft designer. He is currently on a rotation supporting 737 MAX Return to Service and 777x Entry into Service. Andrew has a B.S. from the University of Michigan, a M.S. from USC, and is a certified flight instructor.
