| Abstract | Abstract : Measurements have been made of the maximum deflection from the Coanda effect of a plane jet by a deflecting surface comprising a circular drum whose diameter was four times the jet nozzle width and which had a small flap attached to it. It was shown that the deflection of this comparatively thick jet is dependent on the jet pressure ratio and only quite small deflections can apparently be obtained for pressure ratios greater than 2. A few tests with a jet of slightly reduced thickness showed that although larger deflections were obtained at low pressures, only small deflections were again possible at pressure ratios greater than 2. Finally, some attempts at boundary layer control with spanwise auxiliary blowing slots on the deflecting surface indicated that some increase in deflection angles may thereby be achieved. |
