“…The elliptical front profile blended with a semi-circular trailing edge and so the aerofoils were considerably more bluff than the thin sections used in Refs. [1][2][3][4]. Interest in such bluff sections arose from the prospect that circulation control could be used to Paper No 953.…”

SummaryTypical performance characteristics are presented for a cascade of two-dimensional bluff aerofoils employing circulation control from a tangential blowing jet. The cascade was tested in various configurations at a freestream Mach number of 0·3 and Reynolds number of approximately 1·5 x 105. Lift and drag coefficients and stream deflection are related to the blowing jet momentum coefficient. The expressions employed for lift and drag eliminate the direct effect of the blowing jet on measured performance, which was found to be influenced strongly by vortex shedding at low jet blowing rates.For the configurations employed, tests showed that the economical application of circulation control on an uncambered blade could produce flow turning angles up to 20°.
