“…Even simple models of flapping flight dynamics involve multi-body, nonlinear, non-autonomous (time-varying) dynamics. One common assumption used in flapping flight dynamic models is that the effect of the wing inertial forces on the body dynamics may be neglected [2][3][4][5][6][7][8][9][10]. The validity of this assumption is a subject of continuing debate; see the recent review of Taha et al [11] or Sun [12].…”

Because of the relatively high flapping frequency associated with hovering insects and flapping wing micro-air vehicles (FWMAVs), dynamic stability analysis typically involves direct averaging of the time-periodic dynamics over a flapping cycle. However, direct application of the averaging theorem may lead to false conclusions about the dynamics and stability of hovering insects and FWMAVs. Higher-order averaging techniques may be needed to understand the dynamics of flapping wing flight and to analyze its stability. We use second-order averaging to analyze the hovering dynamics of five insects in response to high-amplitude, high-frequency, periodic wing motion. We discuss the applicability of direct averaging versus second-order averaging for these insects.

Abstract-The dynamics of flapping wing micro aerial vehicles (MAVs) is studied in this paper. The MEMS Laboratory in Tamkang University has been developing flapping-wing MAVs for several years. Based on the developed flapping-wing MAVs we study its dynamics and compare our results with flight test data. Although several papers have discussed similar topics previously, using our flight test data we demonstrate the validity of the assumptions and derivations. We also propose a claim that links the average aerodynamical forces to the wind tunnel test data, so that a flapping MAV can be analyzed with the same methodology as what we have done to a fixed-wing aircraft. Flight test data and numerical simulations are also provided to demonstrate the validity of our derivation.

“…Where C 3.5 ≈ is the aerodynamic force coefficient, derived empirically in (Dickinson et al, 1999;Schenato et al, 2003) and f C is a coefficient chosen so that the aerodynamic force is 20% greater during downstroke than during upstroke. This dissymmetry between the two half strokes can be justified based on (Dudley, 2002).…”
