Abstract : An empirical method for quickly and reliably predicting normal force coefficient and center of pressure for a variety of bodies of revolution over a Mach number range of 1.5 to 3.5 and an angle of attack range of 0 to 24 degrees is presented. Within the method there is included a means for directly adjusting existing normal force coefficient and center of pressure data to account for changes in body length. The application of the empirical method is restricted to a specific class of configurations. These body geometry restrictions concern total length and nose bluntness. (Author)
