Abstract :In this study, an engineering method is presented for computing the aerodynamic characteristics of missiles with circular, square, rectangular and elliptical cross sections. To predict the normal force coefficient values for a rectangular body, a formula was developed to modify Cdn values for noncircular cross sections. This semi-empirical method was applied to predict viscous separation cross flow and potential cross flow terms for the body alone. The geometric variable considered in this study was the body cross section. The aerodynamic characteristics of missiles for the bodies alone were computed for different Mach numbers. The predicted aerodynamic characteristics were in good agreement with the results in the literature.Keywords : missile, aerodynamics, normal force, center of pressure
