Abstract:

The SPINNER computer program has been updated to compute aerodynamic coefficients for a wide variety of spin stabilized projectile shapes. Improvements over the original program are substantial as ogive radius, meplat diameter and rotating band diameter are accounted for instead of assuming mean values. Test cases are shown comparing the 1969 SPINNER, the 1973 SPINNER and experimental data. Input instructions and sample program outputs are given along with the 1973 program listing.
