| Summary: | The aerodynamic efficiency of the Swift (Apus Apus) and its resultant wing morphology merit further study for applications towards micro aerial vehicles (MAVs). Three bio-inspired wing planforms form the focus of this study to investigate the impact of sweep and spanwise chord variation on their local flow physics. The suction side flow characteristics are investigated using 2D particle image velocimetry (at Re = 4.0 × 104 and 6.0 × 104) to identify the effects induced by the planform geometry, followed by direct force measurements (at Re = 6.0 × 104) to correlate the observed flow dynamics to the measured lift and drag force contributions. The trailing wake observation is further conducted for the two wing geometries (at Re = 1.0 × 105) with identical span and area to determine changes associated with the downstream location and observe the development of the trailing wingtip vortex. |
