Summary

This report describes a series of steady and time dependent pressure measurements on a half-model of a rectangular wing of aspect ratio 4. The wing was mounted on a halfbody attached to a sidewall of the RAE 8 ft x 8 ft windtunnel and the tests were made at Mach numbers of 0·60, 0·70 and 0·80 with fixed transition and a Reynolds number of about 2·4 x 106 at the highest Mach number. The wing was oscillated about its mid-chord axis at four frequencies giving frequency parameters up to 0·27 at M = 0·80. The static angle of incidence was varied from -10° to + 10°; here interest is centred on angles of incidence for which the flow on the upper surface of the wing is separated.

Selected mean and oscillatory measurements are offered as a challenge to computational fluid dynamicists for this simple threedimensional configuration. The measurements are of particular interest because the transonic flows include both incipient and well developed separations.
