  • Superconducting railgun. Current from a DC power supply flows between the rails through the superconducting material with a component at right angles to the elongated direction of the rails. The device features rails made from ceramic materials capable of becoming superconducting at relatively high temperatures. Ideal launch efficiencies neglecting Joule losses and assuming constant rail current during the launch are shown to be 50 percent for normally conducting systems, and up to 100 percent for systems with superconducting augmentation. passing an electrical current through the railgun, the Lorentz force pushes the Superconducting augmentation consists of a superconducting coil operating in the persistent mode closely coupled magnetically with a normally conducting rail gun. Although feeding current to a multi-turn coil armature might not require currents as large as those required in a railgun, the elimination of the need for high speed sliding contacts is an obvious potential advantage of the induction coilgun relative to the railgun. Projectile velocities increase by more than 50% and launch efficiencies increase by more than a factor of two depending on the SARG features a superconducting coil closely coupled magnetically to the rail gun and operating in the persistent mode. The calculated actual launch efficiency of 30. The energy efficiency results from the superconducting coils ability to recover the rail magnetic field energy normally dissipated at the end of launch in rail guns, by means of a unique application of the flux The Lorentz force due to the magnetic field Bz on the conduction electrons in the crosspiece has an axial component, Fy = ρ−v ˆx Bz ˆz ✪ × dVol = c ρ−vBz v − dVol = ✪ Superconducting augmentation consists of a superconducting coil operating in the persistent mode closely coupled magnetically with a normally conducting rail gun. Some embodiments utilize rails made entirely from superconducting ceramics while other embodiments utilize rails with metallic cores covered by layers of superconducting ceramics. Projectile velocities and launch efficiencies increase significantly depending on the magnetic coupling between the rail and In order to verify the feasibility of the repetitive superconducting IPPS and study its driving characteristics, the dynamic launching process of a simple 4-m-long railgun system was simulated. The efficiency and the launching force of the rail gun is enhanced by the flux trapping property of a closed superconducting coil causing a significant increase in the magnetic field strength. 3 percent when an adjunct system of superconducting augmentation coils is added, even when using The simple rail gun and rail guns with normally conducting and superconducting augmentation are discussed using an energy approach. Projectile velocities and launch efficiencies increase significantly depending on the magnetic coupling between the rail and A rail gun projectile includes superconducting material. The energy efficiency results from the superconducting coil's ability to recover the rail magnetic field energy normally dissipated at the end of launch in rail guns, by means of a unique application of the flux conse Does constructing rails in a rail gun from superconducting material make the gun more powerful? Will that produce a stronger magnetic field (denser magnetic field strength) than if we use "normal" conductors? Both the energy efficiency and projectile velocity of a rail-gun system can be substantially increased by the addition of an adjunct superconducting augmentation coil system. The superconducting material is of a type that the current flowing through it produces a force for driving the projectile longitudinally along the rails. The energy efficiency results from the superconducting coil's ability to recover the rail magnetic field energy normally dissipated at the end of launch in rail guns, by means of a unique application of the flux An energy approach has been used assuming constant rail currents to compare the actual launch efficiencies of an air defense simple rail gun (SRG) with a similar superconducting augmented rail gun (SARG). If a superconducting railgun is used, according to the Josephson effect, and if the spacing between the armature (projectile pusher on the circular railgun) and the railgun is about a scale of A railgun with superconducting rails. A railgun has few parts: a pair of parallel conducting rails inside a barrel, an armature that rides the rails, and a projectile in front of the armature [see diagram, "Gun Control," above]. . Energy requirements of an actual This patent describes a projectile for launching from a rail gun including first and second parallel, elongated electrically conducting metal rails insulated from each other and connected to opposite terminals of a DC power supply. perconducting augmen- tation coil system. Metal abutting A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a ranged weapon, that uses electromagnetic force to launch high- velocity projectiles. The projectile comprising a forward portion, a rear portion, and an armature between the forward and rear portions, the rails and projectile armature being arranged Superconducting augmentation consists of a superconducting coil operating in the persistent mode closely coupled magnetically with a normally conducting rail gun. A theoretical investigation of the effect of this system on a rail gun has shown that two benefits occur. 5 percent for an SRG is increased to the 46.
