Determination of Normal Forces Arising from In-Bore Pressures on an N- Segmented Sabot: Single Flechette
Abstract
A theoretical model for determining the normal forces produced on an n-segmented sabot during the interior ballistic cycle was developed. While the model considers frustrums of cones and includes the cylinder as a special case, the vector methods employed can be extended to any shape. This model assumes that the sabot can be approximated by segmented rigid bodies positioned symmetrically and individually spaced about the projectile. Results indicate that the composite normal force increases directly with the number (n = or > 2) of segments and approaches a limiting value as n approaches infinity. Furthermore, it is shown that sixteen segments approximates this limit to within 0.7 percent. Knowledge of the normal force can be used to develop conditions for preventing sabot/projectile slipping, as well as establishing material requirements.
