“…UT-CEM was testing the first U.S. Army prototype iron core compulsator (CPA) when dramatic performance increases appeared as a result of moving from plasma to solidhybrid armatures [3]. The benefit in efficiency, particularly at lower velocities (under 4 km/s) had also been studied and verified by others including Barber [4].…”

Abstract--The need to evolve and make more efficient design tools for use in complex railgun system trade studies has led to an enhanced design for a fully integrated hybrid metal contact launch package for railguns. During work on two successful railgun projects at The University of Texas at Austin Center for Electromechanics (UT-CEM), an algorithm was designed which has produced what appears to be a strong design candidate for an aluminum double ramp integrated launch package (ILP). Using only four user inputs, the code produces railgun bore configurations (simple or augmented) and detailed ILPs which minimize the energy requirements for the compulsator. The output design gives useful mass fractions very close to the pinnacle of what is possible without more extensive use of composites.This paper describes the design process used to optimize the railgun bore and ILP. Included is an advanced concept generated by the algorithm along with a detailed 3D structural analysis of the ILP based upon a current profile that is relevant for high performance applications.

“…The model for this design was assembled and executed in FORTRAN and results were compared to many earlier designs [1][2][3][4][5][6][7][8][9][10][11]. For the purpose of validation, an ambiguous 2,300 m/s launch package was designed and validated using a dynamic 3D mechanical finite element analysis.…”

“…Among the potential applications for railguns rapid fire systems have been discussed for a long time [1][2][3][4][5]. In fact the electric launch technology may outclass classical powder guns not only with respect to muzzle energy but also regarding the maximal cadences to be obtained.…”

This paper reports on the rapid fire railgun (RAFIRA) project recently launched at ISL with the aim of investigating the multishot capacity of the armature technology used at the ISL. The latter is characterized by the use of multiple metal fiber brush armatures. The project started with the development of a new medium caliber launcher (25 mm x 25 mm) named RAFIRA and a suitable loading system, as described in part I of the set of papers. This part II summarizes the major results obtained with RAFIRA in single-shot mode and briefly explains the method of optimizing its performance. The experimental realization of the loading system described in part I is presented. First results regarding the performance of this loader are presented. Suitable conditions allowing multishot experiments were worked out. The paper concludes by presenting the first multishot experiments performed using the ISL armature technology. Already in the first tests, RAFIRA has accelerated projectiles up to more than 1000 m/s, while achieving cadences around 30 Hz. The sliding contact performance of these experiments is briefly discussed.

“…Nevertheless, the problem of matching the parameters between ACPA and the flashlamp load is complicated. References [5,6,7] are based on the experimental data of the particular compensated pulsed alternators. References [10,11] have already calculated and analyzed the characteristic parameters of current waveform of ACPA, as well as the parameters of machine effecting.…”

this paper presents a nontraditional Laser power system which an active compensated pulsed alternator (ACPA) drives the flashlamp directly instead of the capacitor groups. As a result, the volume of the laser system is decreased because of the high energy density of ACPA. However, the matching between the output of the alternator and the laser flashlamp is significant and needs to be well analyzed. In order to solve this problem, based on the theory for ACPA, the author proposes a simplified model for the system of ACPA with the flashlamp load by the way of circuit simulation. The simulation results preliminarily illuminate how the performance of the ACPA laser power system is effected. Meanwhile, the simulation results can also supply a consultation for the future ACPA laser power system design and control.
