ESDU 96033 presents an empirical method applying to cylindrical bodies with or without conical boat-tails, at angles of attack up to 25 degrees and Mach numbers up to 5. The method requires a value of the base drag at zero angle of angle of attack which may be obtained from ESDU 76033, 78041 and 79022 for subsonic, transonic and supersonic speeds, respectively. There must be at least three diameters of cylindrical section upstream of the boat-tail and the boundary layer must be fully turbulent. The method is accurate to within 0.03 in axial force coefficient based on body maximum cross section. Comparisons of predicted with experimental results are shown. A worked example illustrates the use of the method.
