Dual leading-edge vortices on flapping wings.
An experimental investigation was performed with two aims: (1) to clarify the existence of the dual leading-edge vortices (i.e. two vortices with the same sense of rotation located close to the leading edge above the leeward wing surface) observed on flapping wings in previous studies; (2) to study systematically the influences of kinematic and geometric parameters on such a vortical structure....
متن کاملThe Unsteady Motion of Slender Wings with Leading-Edge Vortices
The unsteady motion of thin, slender wings with leading-edge vortioes is considered. Incompressible flow and slender-wing theory are assumed throughout , and use is made of an analogy between the unsteady flow and related steady flows. The particular motions treated are: (i) a sudden plunging motion, or change of incidence, (ii) entry into a gust, For the first case, it is shown that the flow i...
متن کاملRotational accelerations stabilize leading edge vortices on revolving fly wings.
The aerodynamic performance of hovering insects is largely explained by the presence of a stably attached leading edge vortex (LEV) on top of their wings. Although LEVs have been visualized on real, physically modeled, and simulated insects, the physical mechanisms responsible for their stability are poorly understood. To gain fundamental insight into LEV stability on flapping fly wings we expr...
متن کاملLeading Edge Vortices
Leading-edge vortices that form at offdesign conditions can profoundly influence the aerodynamic characteristics of highly swept slender wings. predict wing geometry effects on the progressive spanwise development of leading-edge vortices is presented. This method, which can account for sweep, camber, twist, airfoil shape, flap deflections, and planform shape, is shown to be a useful tool for a...
متن کاملApplication of Variable Leading-Edge Roughness for Transition Control on Swept Wings
For transition to turbulence in crossflow-dominated swept-wing boundary layers, details of the strongly nonlinear nature of the stationary primary instability are well understood both experimentally and theoretically. It is the particular action of the nonlinearities that makes possible a transition control scheme using subcritically spaced leading-edge surface roughness arrays. What is desired...
