Coilgun Technology at The Center for Electromechanics, The University of Texas at Austin
The engineering trade-offs performed on a coilgun design are described. The concept used was that of a collapsing field accelerator. This concept was chosen because of its passive operation, and because it lent itself to ...
Research on coilguns at the Center for Electromechanics at the University of Texas at Austin (CEM-UT) has yielded considerable insight into the optimal design of coilgun structures. This research has indicated that the ...
Rapid Fire Railgun For The Cannon Caliber Electromagnetic Gun System
A rapid fire railgun launcher has been designed and fabricated and a single-shot prototype has been tested for the Cannon Caliber Electromagnetic Gun (CCEMG) System. Three, five round salvos of 185 g launch packages are ...
Design of a Rising Frequency Generator/Coaxial Accelerator
The Center for Electromechanics at the University of Texas at Austin (CEM-UT), has designed a high efficiency, low mass and volume, matched rising frequency generator (RFG), and coaxial accelerator system to launch a 22-MJ ...
Solid Armature Wear Modeling
Design of a Reluctance Accelerator
The design of a reluctance accelerator is described, and the methods used in its design are discussed. The methods of control of the accelerator and its predicted performance are also discussed. Because this device contains ...
Experimental Results from CEM-UT's Single Shot 9 MJ Railgun
A 10-m-long, 90-mm bore railgun has been designed and fabricated. During the test program, a number of solid armatures and projectile packages have been tested in a 50-m-deep vertical test range. The experiments are powered ...
Parameter Studies for Traveling Wave Coaxial Launchers
The traveling wave coaxial launcher is a complex machine that requires very extensive parameter studies to optimize. Most of previous attempts to realize hypervelocity using coaxial launchers have failed partly due to ...
Three-Dimensional Rail-Current Distribution Near the Armature of Simple, Square-Bore, Two-Rail Railguns
Vector potential is solved as a three dimensional, boundary value problem for a conductor geometry consisting of square-bore railgun rails and a stationary armature. Conductors are infinitely conducting and perfect contact ...
An Actively Switched Pulsed Induction Accelerator
A coaxial accelerator which will launch a 45 mm diameter, 225 g-mass to 2000 m/s is described. The launcher is a true induction device, as no current feed to the armature is provided. The armature is a multiturn design, ...
