Abstract:
Wind tunnel measurements of lift, pitching moment and drag on one plane and two cambered wings of "mild ogee" planfom (p = 8/15) are reported. These measurements are supplemented by vapour screen and oil flow observations. The wings were designed by slender wing theory for attached flow along the leading-edge at particular values of lift and pitching moment. The design and measured attachment conditions agreed fairly well. The non-linear lift developed could be related with the type of vortex development above the attachment incidence.
