摘要: ▪ Abstract In this review we describe the aerodynamic problems that must be addressed in order to design a successful small aerial vehicle. The effects of Reynolds number and aspect ratio (AR) on performance fixed-wing vehicles are described. boundary-layer behavior airfoils is especially important flight regime. results experimental studies, including influence laminar separation bubbles, discussed. Several examples unmanned (UAVs) regime Also, brief survey analytical models for oscillating flapping-wing propulsion presented. These range from earliest where quasi-steady, attached flow assumed, those account unsteady shed vortex wake as well aeroelastic flapping wing. Experiments complemented analysis led ornithopter also
