Book excerpt: The possibility for balloting-energy growth is examined. The basic equations are developed and the important parameters for balloting motion are obtained and discussed. It is concluded from the analysis that balloting-energy growth can not occur for the balloting model assumed in the present treatment.

Available in PDF, EPUB and Kindle. Book excerpt: This is the second of three basic reports dealing with the in-bore balloting motion of a projectile launched in an electromagnetic railgun. The first report addressed axial projectile motion without cocking and was titled 'A Basic Single Model of In-bore Motion of Railgun Projectiles.' Understanding the inbore motion of a projectile is important to its design and its ability to hit a target with some effectiveness. Analysis of in-bore motion is a complicated problem since many parameters are involved and the interacting relationships between them must be determined. To make the problem easier to understand, it was analyzed on several levels beginning with the basic simple model which computed only the axial motion and followed by more complicated models in the upper analysis levels that included as many lateral forces and gun tube vibration effects as possible. This report deals with the second basic or zero level of balloting analysis. A basic simple model considering only the effect of the propulsion force, the friction force of the armature, and the clearance between the projectile and the barrel is presented. The computation of the axial projectile motion with a certain cocking angle is the goal of this analysis. Equations of motion are derived and solved. A sample computation with available data is performed and the results plotted to give a clearer understanding of balloting action.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final of three reports dealing with the in-bore balloting motion of a projectile fired from an electromagnetic railgun. Knowledge of projectile in-bore motion is important to its design and the design of the railgun. It is a complicated problem since many parameters are involved and it is not easy to determine the interacting relationships between them. To make the problem easier to understand it was analyzed on several levels. Beginning from the basic simple model which computed only the axial motion, more complicated models were introduced in upper levels that included the more significant lateral forces and gun tube vibration effects. This report deals with the approximate analysis of balloting motion. This model considers the effects of the propulsion force, the friction force of the projectile package (projectile and armature), air resistance, gravity, the elastic forces, and the projectile/ barrel clearance. To simplify the modeling, a plane motion configuration is assumed. Though the projectile is moving with a varying yaw angle, the axes of the barrel and the projectile package, and the projectile center of gravity are always considered in a plane containing the centerlines of the rails. Equations of motion are derived and solved. A sample computation is performed and the results plotted to give a clearer understanding of projectile in-bore motion.

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.

Book excerpt: This work documents the BALLOT2 computer program which may be used to compute the in-bore or balloting motion of a projectile launched in a stationary smooth gun tube. The term smooth gun tube means that the gun tube has straight rifling only or nor rifling at all. The presentations include all the main equations, the program symbols or codes, the flowcharts, the preparation of the input data, the output of computation results, the operation of the program, and the program usage. The program may compute the effects of eccentricity of projectile c.g., axial c.g. location, rotating band properties, projectile dimensions, initial projectile position, bore diameter, friction forces, air resistance, etc. The results of computations are arranged to be printed out in tabular form, plotted in figures, and recorded on a magnetic tape. An example is included to show the data arrangement and the computed results. (Author).
