Dynamic Modeling of Insect Flight Mechanisms
Mark Jankausi, University of Washington
Abstract: While inspiration from biology has revolutionized engineering design, even the most advanced manmade systems are consistently outperformed by their biological counterparts. For example, airborne insects exhibit robust flight stability and dexterity unparalleled by micro air vehicles. Although research efforts by engineering and biology communities have significantly advanced the understanding of flapping-wing flight, many of the mechanisms employed by small-scale biological fliers are still poorly understood. In flight, insect wings undergo substantial bending and torsional deformation, activating mechanoreceptors in the process; it is widely believed the neurological feedback generated by these mechanical sensors is essential for both posture control and robust disturbance rejection. During this talk, I will elucidate the role of the wing as both a sensor and actuator and discuss recent advances in structural modeling of flexible wings. I will review the multi-physical (aero and inertial dynamics) problem of insect maneuverability and highlight the prominence of inertial forces on gross trajectory shaping. The presented results inform the much needed optimization of small-scale aerial robotics and provide the theoretic framework for rigorous studies in insect sensorimotor coordination.
Bio: Mark Jankauski is currently a postdoctoral research associate at the University of Washington. He received his B.S. degree in Mechanical Engineering in 2011 and subsequently worked in industry for a year as an Instrumentation & Controls Engineer and Mechanical Estimating Professional for CH2M Hill. Mark began graduate school at the University of Washington in 2012, where he received his M.S. (2014) and Ph.D. (2017) in Mechanical Engineering. He received a best-paper award at the International Conference of Micro Air Vehicles in 2014 for his research on flexible wing mechanics and a College of Engineering Student Teaching Award in 2016 for instructing classes in dynamics, vibrations, and finite element analysis.
