03.1 - Aerodynamics – CFD Methods and ValidationNUMERICAL SIMULATION OF PITCHING MOTION EFFECTS ON THE AERODYNAMIC PERFORMANCE OF DRAGONFLY-LIKE FLAPPING WINGX.-Y. Lang¹, B.-F. Song¹, W.-Q. Yang¹; ¹Northwestern Polytechnical University, China Pitching motion has great impact on the aerodynamic performance of dragonfly-like wing’s hovering motion.Various pitching amplitudes have been numerically investigated. When pitching amplitude equals 45°, the tandem wing will obtain the optimal vertical force. The research in this paper is helpful to understand the flight mechanism of dragonflies. |
