NEW TWISTS IN THE LEADING-EDGE VORTEX

Journal of Experimental Biology, 2004
![Figure][1] Insects aren't airplanes. If they flew like airplanes, they would fall right out of the sky because their wings are much too small. But since they flap their wings, they can generate a `leading-edge vortex', a rotating element of fluid along the front of the wing ...

Control of leading edge vortex breakdown by blowing

26th Aerospace Sciences Meeting, 1988
An investigation into the effects of using a jet of air to control the vortex breakdown position on a 70 degree delta wing is presented. The specific objectives focused on optimizing the blowing positions in terms of maximum lift increments obtained for minimum blowing rates.

Numerical simulation of leading-edge vortex flows

17th Fluid Dynamics, Plasma Dynamics, and Lasers Conference, 1984
Steady flowfields describing respectively the distinguished structure for subsonic, sonic, and supersonic leading-edge flow about a thin delta wing at angle of attack in a supersonic freestream are calculated numerically. Solutions of the steady three-dimensional compressible laminar Navier-Stokes equations are obtained by time integration.

Vortex separation above delta leading edges.

Journal of Aircraft, 1967
and that the jet flow would attach at the inlet lip. The inspections of Fig. 4 shows that the round lip, created by the jet flow, extended well inside the inlet lip and restricted the inlet flow area. Thus, the pressure recovery improvements that might have been realized as the result of rounding the lip were offset by higher pressure losses associated

Slender Wings with Leading Edge Vortex-Separation

1982
The demands of high speed performance and maneuverability on modern transport- and fighter-aircraft require slender wings, whose leading edge vortex flows result in increased lift at high angle-of-attack. Beginning with the experimental and theoretical development and the history of application the article will discuss the application of panel- and ...
