A Ring Source Method for Predicting the Aerodynamic Characteristics of Bodies of Revolution.

'The views expressed herein are those of the authors alone and do not neeessurily represent those of the Institute. " SUMMARY A method is presented for determining the potential flow around bodies of revolution at incidence and yaw in uniform flow, and in curvilinear flow. This method utilises the ring source method of Hess and Smith (Ref.l) and gives substantial advantage over existing techniques. When compared with the method of Petrie (Ref. 3 and 4), in a typical case, the computer run time is almost halved. The method is applicable to a wide class of bodies, both pointed and blunt, and determines both surface and flow field conditions. By its nature it is, of course, limited to low total angles-of-attack
