 Abstract

Measurements of the distribution of heat-transfer coefficient and static pressure have been made in free flight on the flat upper surface of a sharpedged delta wing of aspect ratio 1 (76º leading-edge sweepback) at 14° incidence. Two configurations were tested differing only in edge angle between upper and lower surfaces, being 26.50 and 900 respectively. From the pressure measurements and some preliminary wind-tunnel tests, it was seen that both exhibited vortical separation at the leading edges with reattachment along the centre line. The heat-transfer coefficient distributions however showed marked differences, particularly in the neighbourhood of reattachment, but for both models were everywhere less than the theoretical values for a flat-plate, based on freestream conditions.
