A wing-design study has been conducted on a 65 swept leading-edge delta wing in which the wing geometry was modi ed to take advantage of the naturally occurring ow that forms over a slender wing in a supersonic ow eld. Three-dimensional nonlinear analysis methods were used in the study which was divided into three parts|preliminary design, initial design, and nal design. In the preliminary desi...

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...

The Drosophila glucoside xylosyltransferase Shams xylosylates Notch and inhibits Notch signaling in specific contexts including wing vein development. However, the molecular mechanisms underlying context-specificity of the shams phenotype is not known. Considering the role of Delta-Notch signaling in wing vein formation, we hypothesized that Shams might affect Delta-mediated Notch signaling in ...

Experiments are performed on a 82.5 sweep flat-plate delta wing combined with a dorsal fin of height 0.6 of the wing semi-span at Reynolds number based on the wing root chord of 3.32×105, in which a pair of small and short dielectric barrier discharge plasma actuators are employed at the wing leading edge near the apex of the wing to effect flow control. Measured pressure distributions over the...
