Abstract:

The effect of the earths rotation on trajectories of the Angled Arrow Projectile is obtained by three methods a numerical integration of the equations of motion including the Coriolis force and by two approximate integration methods applied to the linear differential equations which define the variations from the range table trajectories produced by the earths rotation. A comparison of sample computations by the three methods indicates that the more exact method of correcting range table trajectories is sufficiently accurate for all purposes while the less exact method is sufficient to give the general magnitude of the effect of the earths rotation but is probably inadequate for use in the AAP fire control computers.
