Summary

By integration of the pressure distributions of Part I of this paper values for the normal force and centre of pressure position (or moment) are obtained herein for the three effects; interference on the body, interference on the wing, and overall body-wing. In order to estimate overall body-wing characteristics the net wing alone and body alone normal forces and centre of pressure positions are also required, methods of estimating these quantities are readily available in the literature (e.g. ref. 2). The present method gives an estimate of overall body-wing normal force which is usually accurate to within 10 per cent and an estimate tor overall cp position which is usually accurate to half a calibre. Comparison of the present method with the method of Nielsen, Kaatari and Pitts shows that there is little to choose between the two so tar as overall estimates are concerned; the present method has the advantage of an associated pressure field.
