Aerodynamic Characteristics of Basic Nose-Cylinder Bodies for Large Ranges of Angle of Attack

Abstract

The existing methods of predicting aerodynamic characteristics for basic blunt-based bodies of revolution are reviewed and accessed. Utilizing the more accurate methods, a digital computer program was developed which uses numerical techniques, thus avoiding less accurate simplifying assumptions. This new approach provides reasonable accuracy in predicting the normal force and moment coefficients of basic model combinations for angles of attack ranging from zero to 90 degrees. This accuracy in prognosis also includes freestream Mach numbers ranging from subsonic to hypersonic.
