Aerodynamics of Maneuvering Slender Wings with Leading-Edge Separation

Non-conical Flow past Slender Wings with Leading-edge

The 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...

Calculations 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 ...

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...

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....
