“…The mass-to-power ratio  was set to 25 kg/kW 27 , which is an averaged value for the power sources most commonly used in space. The energy efficiency of the railgun was set to 30% 29 , hence approximately one third of the electrical energy generated by the power source is transformed into kinetic energy:…”

“…In the literature, a value of 100-300 m/s is suggested as a realistic excess velocity for the expelled mass 28; 30 , therefore, in this paper, an excess velocity of 200 m/s, which is within the current technological capabilities 29 , was considered for all the analysis. Given the excess velocity, the mass expelled per shot can be calculated with the following equation: …”

“…Magnetic railgun systems have already been developed and used on Earth for other applications 29 , therefore we can assume a TRL 5, rendezvous and landing is TRL 7 as for other methods as well as nuclear power. The anchoring system and the mining system in microgravity instead require a substantial development 31-32; 48-49 , thus their TRL is no higher than 4.…”

“…The multiple brushes decrease the current density for each brush and allow for a good metal to metal electrical contact. Experiments with longer and heavier projectiles of up to 4 kg were performed at the PEGASUS facility [6]. The largest velocity achieved so far with a 300 g projectile is approximately 2500 m/s.…”

Nowadays rockets are the unchallenged workhorses of launch to Space. This technology generally suffers from a small payload to total weight ratio and requires large amounts of chemical fuels. Electromagnetic launch technology and more exact railguns, are promising candidates for the launch of smaller masses. Since several years the ISL has conducted railgun research and in this context studied possible space applications. Here two scenarios are presented and discussed.

“…The use of accelerators for fatigue testing of materials has many advantages: wide measuring range, high velocity impact tests and the possibility of using a ballistic part with different face geometry. These advantages allow to use accelerators in the material testing in industry, in military and especially in the area related with exploration of the space [9].…”

Abstract. The main objective of the research is to investigate, how the power supply parameters influence the kinetic energy of the movable element, called commonly a projectile or bullet. A calculation and measurement results of transient characteristics for an electrodynamic accelerator with permanent magnet support were presented in the paper. The calculations were made with using field-circuit model, which includes the parameters of the power supply, mass of the bullet and friction phenomenon. Characteristics of energy and muzzle velocity verso supply voltage (50 V to 350 V) and capacitance value (60 mF to 340.5 mF) were determined, as well. A measurement verification of selected points of calculation characteristics were carried out for investigated values of muzzle velocity. A good conformity between calculation and measurement results was obtained. Concluding, presented characteristics of the muzzle velocity and energy of the projectile vs. power supply parameters indicate, that accelerators could be used for fatigue testing of materials.
