Abstract

The flow over an insect wing can be highly influenced by the wing aspect ratio (AR), affecting the aerodynamic forces. Previous studies present apparently contradictory effects of AR, creating a challenge in selecting the optimum AR in the design of insect-inspired micro air vehicles. Some recent studies indicate that the AR-effects are coupled with those of the Reynolds number and Rossby number. The
present study investigates the individual effects of these three parameters and suggests that the use of the span-based length scale decouples their effects. This also helps reconcile the past AR studies.
