Book excerpt: This interim report presents the formulation of a system of simultaneous differential equations which describes the general motion of a projectile of finite geometry and inertia traveling in a flexible gun tube. The formulation permits the projectile six degrees-of-freedom relative to the gun tube; three orthogonal translational motions of the projectile c.g. relative to the instantaneous gun tube axis and three (Eulerian) rotational motions of the projectile about it c.g. The formulation is presented in terms of interior ballistics data, projectile design data, and gun tube design and motion data. The formulation accounts for projectile spin, mass eccentricity, elastic deformation of the projectile rotating band and bourrelet, and projectile/bore interfacial friction and torque transmission. Furhtermore, the formulation is unrestricted regarding the nature of gun tube motion. The formulation has been compared with projectile descriptions and formulations employed by other investigators and, based upon this comparison, isconsidered to be the most generally applicable projectile in-bore motion formulation appearing in recent literature.

This book was released on 1973 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic behavior of a projectile during acceleration in the gun tube requires a quantitative description, since, if balloting becomes excessive, undesirable conditions such as damage to fuzing, shell body engraving, inaccuracy of fire due to yaw, and yaw velocity at the muzzle may result. The approach taken in this report utilizes the equations of motion derived in an earlier report titled, 'Transverse Motion of an Accelerating Shell' to describe the balloting motion of the 8-inch XM673 projectile fired in the MK-16, MCLG gun, XM201 and M2A2 gun tubes. Most previous solutions which have appeared in published works to date discuss the problem in a simple way, or consider separately the main factors that effect projectile motion. Effects of friction forces at the bourrelet and the driving band, changes of the eccentricity and the location of the center of gravity, and the wall thickness of the shell were considered in this formulation. The analysis shows that the contact of the bourrelet on the gun tube is intermittent when the C.G. eccentricity is zero or very small and the contact is continuous when the eccentricity is large and that this parameter is the one that most affects the performance of the projectile and the associated fuze. The analytical results are presented in graphic form.

Book excerpt: Each of the four main sections in this report deals with the motion, the forces, and the moments experiences by a gun tube with a straight axis and an offset breech, and with certain simple types of support. Section I presents a development of the kinematics of a projectile in a concentric moving flexible tube. Section 2 treats the forces and moments that act on a projectile in terms of kinematic variables of the tube. Section 3 treats the motion of a tapered cantilever tube that is actuated by the projectile and by prescribed motion at the breech. In Section 4, the problem of a rigid curve tube that is hinged at the breech so that it can swing sideways is treated.

This book was released on 1974 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
