Sabot Aerodynamics During Discard.

Abstract

The aerodynamics of a generic sabot piece is treated using the Newtonian approximation. The sabot piece is composed of an inner and outer cylindrical surface, conical surfaces on either end, and longitudinal slices parallel to the axis. When assembled, an integral number of such similar pieces form an annular cylinder. A computer program is included which gives the Newtonian lift, drag, and moment coefficients of the piece in terms of the front and rear cone angles, length, ratio of inner to outer radii, and number of pieces. Only pitching motion is treated, and no aerodynamic interference between sabot pieces or projectile is considered. A discussion of a model for sabot discard is given.
