Abstract : This present report is intended to be used in the formulation of quick estimates of the static aerodynamic characteristics of the conventional flared projectile. The data is based primarily on References 2 (E.D. Boyer, 'Free Flight Range Tests of a Minuteman Re-entry Stage Model') and 5 (AMCP 706-280, 'Design of Aerodynamically Stabilized Free Rockets'), and the exposition follows that of the corresponding finned projectile presentation. The drag, static moment and normal force coefficients are determined from the simplified geometry of the projectile and the bounding aerodynamic conditions, i.e., sea level, flat fire, 2M5, and small yaw. The computer program is written in the Hewlett-Packard Basic Language and is easily to other BASIC-language microcomputers.
