Rept. no. 22G-5 Contract AF 196047400 AFESD TDR 62-81Unclassified report DESCRIPTORS Conical bodies, Aerodynamics, Drag, Ballistics.A simple formula for the Newtonian drag coefficient is derived for t e blunted cone-sphere ice-cream cone at small angles of attack. Gr p s are presented for the drag coefficient as a function of cone semi-vertex angle from 6 to 30 deg and bluntness ratio nose-radiusbaseradius ranging in tenths from 0 to 0.5. For given values of the body parameters, the weight required for the body to attain a prescribed ballistic coefficient is then determined. Fineness ratios for different specified cone-anglesAND DEGREES OF BLUNTNESS ARE PROVIDED FOR REFERENCE. Author
