Experimental pressure distributions, lift, moment and drag coefficients on the wing-body combination are measured. Data were obtained at angles of attack from-10 degree to 10 degree, a free stream velocity of 40 m/s and Reynolds numbers based upon wing chord lengths from 0.32×10(exp 6) to 0.43×10(exp 6). The data obtained from these experiments are compared with data obtained from computations using a boundary element method which is a modification of Morio’s theory. In order to confirm the starting points of the trailing vortex sheets on the body, observations of the flowfield by an oil flow technique are presented and the features of the oil film flow patterns are discussed. It is concluded that the present procedure may offer promise for practical engineering applications.
