Over the last two decades, several mechanisms of armature transition have been postulated. Each mechanism has been subjected to experimental and analytic examination with the objective of "explaining" transition. However, no single mechanism has emer

Low parasitic mass, high muzzle velocity railgun launch packages are required for railguns to compete with conventional guns. This paper describes a launch package concept for long rod penetrators which has the potential of achieving less than 50% pa

A railgun barrel has been designed for 90 mm multishot, rapid fire application. This new design is based on the laminated metallic railgun structure design that IAP has employed in constructing railgun barrels which are currently in use in several la

Bore life is one of the most difficult technical issues confronting railgun development for practical use. Material testing for wear and erosion using a railgun is a very slow and expensive method for developing many shot life data. We have built and

A Distributed Energy Store (DES) powered railgun has been built to evaluate DES projectile acceleration performance and launcher efficiency. We describe the design, fabrication, and initial test results of the launcher, lightweight launch package, an

Material deposition on the rail in railguns from sliding armatures during nonarcing contact phase must be minimized to meet the Electromagnetic Armament System Focused Technology Program (EMAS FTP) program requirement for rail variation over the life

Railgun launchers must be energy efficient to realize use in practical systems, especially mobile applications which require compact power supplies. This paper shows that railgun launcher efficiency has already been demonstrated at 47 percent at laun

Railgun armature contact forces are often treated as a "quasi-static" parameter. The magnetic loading of the armature is treated as time varying, but the structural response is treated statically. In this paper, the authors look at the dynamic respon

This paper reviews the design features and performance characteristics for a large bore (90 mm) barrel system fabricated for the Defence Research Agency (DRA) to operate at the Kirkcudbright Electromagnetic Launch Facility. This 90 mm barrel was desi

Integrated launch packages in round bore railguns are designed to support acceleration forces based on a given current distribution in the armature/sabot. Deviation from this current distribution can lead to loads for which the launch package is not
