Available in PDF, EPUB and Kindle. Book excerpt: The acceleration of projectiles through the use of electromagnetic forces (Railguns) has many advantages over conventional methods. Foremost are the higher velocities which can be achieved and the reduction in firing platform sensitivity to hits. Projectile velocities on the order of 3-4 kilometers per second allow the use of 'kinetic energy kill' projectiles which are effectively inert munitions. Additionally, by using purely electromotive force for the acceleration, the need for explosive propellants is eliminated. A one meter Electromagnetic Railgun was designed and constructed to serve as a test bed for research into alternative armature materials, rail/armature plasma effects, and current pulse forming techniques. A modular approach was used to allow independent changes in power supply, pulse forming network, bore configuration, and gun augmentation.

Book excerpt: As the magazine of the Texas Exes, The Alcalde has united alumni and friends of The University of Texas at Austin for nearly 100 years. The Alcalde serves as an intellectual crossroads where UT's luminaries - artists, engineers, executives, musicians, attorneys, journalists, lawmakers, and professors among them - meet bimonthly to exchange ideas. Its pages also offer a place for Texas Exes to swap stories and share memories of Austin and their alma mater. The magazine's unique name is Spanish for "mayor" or "chief magistrate"; the nickname of the governor who signed UT into existence was "The Old Alcalde."

This book was released on 2001-12-01 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: A naval electromagnetic railgun would be a considerable asset against a littoral environment. By accelerating projectiles to 3 km/s, a naval railgun would be capable of reaching 300-400 nautical miles. Problem such as rail erosion, energy storage and fire control prevent the railgun from becoming a weapon to date, At the Naval Postgraduate School, the Physics Department continues to investigate and develop concepts to overcome these challenges. As part of the methodology, previous students built a one-meter railgun system for experimentation. The existing 1.6 mF power supply is insufficient to fire this railgun effectively. To design a sufficient power supply a MATLAB code was created to simulate a generated current pulse and to predict the subsequent railgun performance. Interrelated factors such as railgun geometry, muzzle velocity, current density and contact surface area were taken into consideration. Also, tradeoffs in capacitance, projectile mass and residual current were weighed against one another to achieve desired railgun performances. From numerous simulations, this study determined that the one- meter railgun with a 21.5 mF power supply could fire a 0.1 58-kg projectile at a velocity of 1 km/s, and leave a residual current of only 4% of the initial energy once the projectile exits the rails.

Available in PDF, EPUB and Kindle. Book excerpt: Long range maritime land attack can be accomplished with today's chemically propelled munitions only by sacrificing responsiveness. Projectiles launched with electromagnetic forces can achieve velocities above 2-3 kilometers per second. The technical challenges to be overcome before electromagnetic launch can be considered practical for maritime land attack include development of high density pulsed power supplies, high current power switching and a long life launcher. To investigate electromagnetic launch technology a 1.2 meter railgun was constructed. It was designed to allow augmentation and various bore configurations. The railgun power unit consists of two 11 kV, 830 microfarads capacitors discharging through a 7 micro-H inductor coil. A crowbar circuit provides capacitor protection. Operational testing of the firing circuit, instrumentation, power unit, and launcher structure was satisfactory. The 7 micro-H coil induced currents within the power unit, which adversely effected triggering circuitry. The molybdenum projectiles initially tested proved disappointing due to their tendency to meld with the copper rails. An extended current pulse resulting from such a meld caused failure of the crowbar circuit, which curtailed further testing. The induction coil could safely be discarded, and a revised crowbar circuit will prevent further failure. Future operational testing will focus on alternative armature materials and designs and on operational methods.
