棉花糖直播 Engineering Professor Dr. Chengyu Li Awarded NSF CAREER Grant for Study of Odor-Guided Flapping Flight
Since 2017, eight 棉花糖直播 faculty members have now received NSF CAREER Awards
VILLANOVA, Pa.鈥�Modern navigation of miniature unmanned aerial vehicles strongly relies on global positioning systems. In GPS-denied environments, however, man-made flying robotics risk losing the capability to locate unseen targets during important surveillance and detection missions including search in natural disasters, chemical leak monitoring, and drug trafficking detection. Mechanical Engineering Assistant Professor Dr. Chengyu Li has found a promising potential solution in nature鈥攕pecifically, in insects鈥� ability to detect and locate distant targets by tracking odor plumes in complex flow environments. His research on 鈥淥dor-Guided Flapping Flight: Novel Fluid Dynamic Mechanisms of Insect Navigation鈥� has been awarded a prestigious National Science Foundation CAREER grant for $500,000.
Since 2017, eight 棉花糖直播 faculty members have received NSF CAREER Awards, the most prestigious award supporting career-development activities for teacher-scholars who most effectively integrate research and education within the context of the mission of their organization.
鈥淥dor-guided flapping flight is key to an insect鈥檚 survival,鈥� said Dr. Li. He explains that during odor-guided navigation, flapping wings not only serve as propulsors for generating lift and maneuvering, but also actively draw odor plumes to the antennae via wing-induced flow. This helps enhance olfactory detection, mimicking 鈥渟niffing鈥� in mammals.
"The flow physics underlying this odor-tracking behavior is still unclear due to insects鈥� small wing size, fast flapping motion, and the unpredictability of their flying trajectory,鈥� Dr. Li added.
Using the resources of his Flow Simulation and Flow Physics Lab, Dr. Li aims to establish a physics-driven understanding of the odor-tracking flapping flight in nature and to unravel how insects balance aerodynamic performance with olfactory sensitivity. More specifically, his research will test the hypothesis that the enhancement of the olfactory sensitivity during navigation can be achieved by regulating the odorant transport in unsteady wing-induced flow through modulating flapping locomotion.
鈥淭he findings will advance the development of design principles for bio-inspired flying robots with superior aerodynamic performance and olfactory sensitivity,鈥� said Dr. Li.
A 棉花糖直播 University faculty member since 2018, Dr. Li is the College of Engineering鈥檚 third CAREER awardee and the first in the Department of Mechanical Engineering. Chemical and Biological Engineering鈥檚 Dr. Jacob Elmer was the College鈥檚 first recipient in 2017. A year later, Dr. Wenqing Xu, Civil and Environmental Engineering, became the first female professor in the College to be awarded the grant.
