Abstract
This paper discusses the effects of wing inertial forces on flight stability and required lift for hovering of insects with a varying stroke plane. In this paper, the stroke plane of a flying insect is called varying if the angle between the stroke plane and insect’s body remains constant during flight. Using a quasi-steady aerodynamic model and averaging techniques, while including the wing inertial forces in flight dynamics, the analytical results show that for an insect with a varying stroke plane the wing inertial forces have destabilizing effects on the insect’s translational motion during hover. Besides, the results suggest that an insect with a varying stroke plane requires less aerodynamic lift than its weight and a nonzero-mean drag for a stable hovering flight. Numerical simulations support the analytical results. To realize the mechanics behind the destabilizing effects of the wing inertial forces of an insect with a varying stroke plane and explain the properties of the lift and drag required for a stable hover, first, the vibrational control of a three degree of freedom force-input pendulum with a varying force direction is discussed.
