Experiments on isolated fiat plates perpendicular to the wind are described. It is shown that the effects of aspect ratio on drag, base pressure and flow pattern are small up to A = 10. All of these rectangular plates shed ...

Root-mean-square intensities and spectra of local pressure fluctuations were measured by transducers at two positions on the inner part of the wing and four on the outer part, while low-frequency pressure fluctuations on ...

Low-speed wind-tunnel tests have been made, under as near two-dimensional conditions as possible, on a wing section with plain leading- and trailing-edge flaps. The increases of lift resulting from boundary-layer control ...

This note considers the effect on the flow over a swept wing, of vertical plates of small height--commonly called 'fences'. It is shown, as might be expected, that the nature of this effect is that of a partial-reflection ...
