The stability of flapping flight, which is a natural requirement for flying insects, is one of the major challenges for micro aerial vehicles. A fully coupled computational model is employed that combines the Navier–Stokes equations and the equations of motion in six degrees of freedom to model the hovering flight of a hawk moth. These simulations are combined with high-speed videogrammetry experiments on live, untethered hawk moths flying in quiescent and perturbed flows. The flight videos are used to identify a potential mechanism that could be used by the moth to stabilize its hovering flight. The effectiveness of this mechanism is then investigated using computational-fluid-dynamics-based simulations and semianalytic approximations. The results of the current study should improve the understanding of mechanisms used by flying insects to stabilize themselves and help to gain insights that can be employed for micro aerial vehicles.
