(Rept. no. 22G-5) (Contract AF 19(604)7400) (AFESD TDR 62-81)Unclassified 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-radius/baseradius) 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)
