Extensive work on slender axi-symmetric bodies in transonic flow has been carried out and well documented in the 1970’s. With the progress of CFD that has taken place in the following decades, codes are available to look into the detailed characteristics of the shock-boundary layer interaction and the resulting wave drag, in particular due to the geometry of the afterbody. However, to the authors’ knowledge, the optimum drag of axi-symmetric bodies need further elaboration. Therefore it is the objective of present work look carefully into the drag mechanism due to geometry of the afterbody, in particular and more significantly, to find a way to optimize the total drag.
