AN EMPIRICAL METHOD OF PREDICTING NORMAL FORCE AND CENTER OF PRESSURE CHARACTERISTICS FOR BODIES OF REVOLUTION AT ANGLES OF ATTACK UP TO 24 DEGREES AT SUPERSONIC MACH NUMBERS,

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)
