The relationship of coefficient of pressure center of body of revolution and angle-of-attack and Mach number was educed, based on the aerodynamic formulas of high-angle-of-attack flow. Adopting a k-ε two-equation turbulence model following the realizable rules, seven kinds of body of revolution with different shapes in high-angle-of-attack flow fields were researched by means of CFD, and the numerical results were derived. The numerical simulation results were consistent with the ones in theoretic analysis. Research results indicate that there is a geometric discriminant, which is correlated with the geometric configuration that has strong influence on the law of variation of the coefficient of pressure center. 
