Yawing and Balloting Motion of a Projectile in the Bore of a Gun with Application to Gun Tube Damage

Abstract

New basis equations of motion are derived to describe in bore shell yawing and balloting motion. It is shown that the prior equations of Reno and Thomas are not satisfactory. These equations are used to derive expressions for the growth of balloting motion. Application of these equations to a mechanical failure of a shell in an 8-in. howitzer XM201 test program shows the new treatment accounts for the observed tube damage. This approach provides a basis for calculating causes and probability of occurrences of severe balloting.
