The Leading-Edge Vortex of Swift Wings
Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the Leading-Edge Vortex (LEV) for lift generation in a variety of flight conditions. A well documented example of an LEV is that generated by aircraft with highly swept, delta shaped wings. While the wing aerodynamics of a manoeuvring aircraft, a bird gliding and a bird in flapping flight vary signi...
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...
متن کاملCalculations of the Flow over Thick, Conical, Slender Wings with Leading-Edge Separation
The vortex-sheet model of leading-edge separation previously applied to flat-plate delta wings has been applied to thick delta wings in the form of rhombic cones. The simplifications introduced by the use of slender-body theory and an asymptotic treatment for the core of the vortex have been retained. The results show that the vortex sheet leaves the wing tangentially to the lower surface. The ...

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...
