INTLIFT

Interim estimates of lift (CLA), overturning moment (CMA), and yaw-drag (CDA2) coefficients for small-arms and medium-caliber projectiles. MCDRAG-format geometry inputs; requires a correct center-of-gravity location.

Projectile geometry (MCDRAG format)

Projectile identification Reference diameter DREF (mm) Total length LT (calibers) Warnings when LT > 7 Nose length LN (calibers) Warnings when LN < 1.5 Headshape RT/R Boattail length LBT (calibers) Base diameter DB (calibers) Meplat diameter DM (calibers) Center of gravity CGN (calibers from nose)

Computes the fixed Mach schedule 0.5–3.0 used by the original BASIC program.
