About
Jo Won Chang is a researcher specializing in insect flight aerodynamics, biomechanics, and experimental fluid dynamics, with a particular focus on unsteady aerodynamic phenomena in flapping-wing systems. His work has made significant contributions to our understanding of how insects like hawkmoths generate and control aerodynamic forces during both hovering and forward flight. Chang's most impactful contribution is his development of an improved quasi-steady aerodynamic model that incorporates the movement of the center of pressure during insect flight (2015, 60 citations). Using dynamically scaled robotic hawkmoth wings, he experimentally derived translational lift, drag, moment, and rotational force coefficients, providing a more physically accurate framework for modeling insect aerodynamics. Building on this, his investigation into advance ratio effects on flapping-wing lift augmentation in forward flight (2016, 56 citations) employed time-varying force measurements and digital particle image velocimetry (DPIV) to systematically characterize how flight speed alters aerodynamic performance across multiple flow regimes. His earlier experimental work with robotic Manduca sexta models established foundational insights into unsteady aerodynamic characteristics at biologically relevant Reynolds numbers. More recently, Chang has extended this research to examine the structural influence of leading-edge wing veins on aerodynamic performance. Together, his body of work bridges biological inspiration and engineering application, informing the design of bio-inspired micro air vehicles.
