Drag Functions for Exterior Ballistics

The drag curves for small projectiles were all emperically derived by the gentlemen for whom the curves are named. Not that much difference exists between the curves (good news since even though the physics behind the drag curves is not fully understood to the point of having deterministic formula(s), one would hope that emperical measurements would be repeatable!). The following pictures show the three drag functions selectable with this exterior ballistics program. The "Ingalls" curve is a modified Mayevski function.

All curves are for "standard" conditions - sea level, 59 degrees F, etc.

Drag functions for velocities up to 5000 fps.
