Abstract:
Skin-friction measurements have been made on a half-model slender wing of 24 ft root chord at low subsonic speeds. The maximum root-chord Reynolds number was 30 x 10power6. The measurements were made using surface pitot-tubes formed by magnetically attaching razor-blade segments to the model surface. The results show that high levels of skin friction are present beneath the leading-edge vortex and are correlated satisfactorily with previous results obtained at lower Reynolds numbers.
