Abstract

In this paper, we have integrated the dynamical equations of the mean twisted trajectory of a spinning shell in terms of step functions similar to those of Siacci. The air resistance is assumed to be a known tabulated function of Mach number. Using our solutions we have calculated the drift of a 3 inch 16Ib. shell which agrees well with the observation. The corrections arising in the various elements of the trajectory are also calculated.
