论文名称：Aerodynamics of a flapping wing with stroke deviation in forward flight

发表刊物：Physics of Fluids

摘要：In this paper, we numerically studied the effect of stroke deviation on the aerodynamic performance of the three-dimensional flapping wing
in forward flight at a low Reynolds number. Six deviation motion patterns with different stroke deviation amplitudes were investigated. The
results show that the distinct patterns exert a substantial influence on the aerodynamic forces of the flapping wing, with a more pronounced
effect at higher values of deviation amplitude. For most patterns, stroke deviation enhances either lift or thrust performance unilaterally. The
maximum lift and thrust of the wing with deviation motion can be 37% and 35% larger than that of the wing without deviation motion. A
detailed analysis of typical flow characteristics underscores the pivotal role of deviation motion in aerodynamic force generation. Finally, two
artificially created innovative deviation motion patterns are proposed, which exhibit an exceptional capacity to augment thrust by up to 123%
or enhance comprehensive aerodynamic performance significantly. These findings establish a theoretical foundation for designing highperformance flapping-wing micro-air vehicles.
