Abstract

A new railgun configuration with perforated sidewalls is investigated. The motivation for this new configuration is the desire to minimize the detrimental effects of inertial and viscous drag at high velocities caused by the debris from the projectile and the gun wall trapped in the plasma armature. The test has been done on a 1.2 m long railgun with a 3.2-mm-diameter bore. Results for hydrogen pellet acceleration show that at high currents the perforated railgun outperforms the unperforated one. Combined with a newly designed cryogenic pellet generator and the first stage gas gun, a solid hydrogen pellet velocity of 2.46 km/s has been achieved on the 1.2-m railgun.

Acceleration of solid hydrogen pellet using augmented railgun for magnetic fusion reactor refueling

Journal Article Zhang, J; Kim, K; King, T - IEEE Transactions on Magnetics

A 1.2-m long electromagnetic railgun with separate augmentation was designed, fabricated, and tested for the purpose of injecting hypervelocity hydrogen pellets into magnetic fusion devices for refueling. A compact configuration of two pairs of coaxial rails insulated by thin Kapton film was employed. Two pulse-forming networks were used to separately control the duration, amplitude, and overlap of the current pulses. Copper sulfate resistors were employed as impedance-matching resistors and bank short resistors. The magnetic field inside the gun bore was boosted by the high current on the augmentation rails, which in turn increased the J x B force without increasingmore »« less

Study of a transaugmented two-stage small circular-bore railgun for injection of hypervelocity hydrogen pellets as a fusion reactor refueling mechanism

Journal Article Tompkins, M; Anderson, M; Feng, Q; ... - IEEE Transactions on Magnetics

Injection of hypervelocity hydrogen pellets has become widely accepted as the most effective means of refueling magnetically confined fusion reactors. Pellet velocities on the order of 10 km/s are desired and hydrogen pellet erosion during acceleration must be minimized. It is important to maintain uniform bore surfaces during repetitive shots, implying that, if a railgun is to be used to accelerate the pellets, damage to the sidewalls and rails of the railgun due to local heating must be limited. In order to reduce the amount of power dissipated within the bore and increase the propulsive force generated by the plasma-arcmore »« less

Results from recent hydrogen pellet acceleration studies with a 2-m railgun

Conference Kim, K; Zhang, D; King, T; ...

A new 3.2-mm-diameter, two-stage, fuseless, plasma-arc-driven electromagnetic railgun has been designed, constructed, and successfully operated to achieve a record velocity of 2.67 km/s({sup b}) for 3.2 mmD {times} 4 mmL solid hydrogen pellet. The first stage of this hydrogen pellet injector is a combination of a hydrogen pellet generator and a gas fun. The second stage is a 2-m-long railgun which serves as a booster accelerator. The gas fun accelerates a frozen hydrogen pellet to a medium velocity and injects it into the railgun through a perforated coupling piece, which also serves a pressure-relieving mechanism. An electrical breakdown of themore »« less

Electromagnetic railgun hydrogen pellet injector: Progress and prospect

Conference Kim, Kyekyoon

A two-stage, fuseless, plasma-arc-driven electromagnetic railgun system suitable for hydrogen pellet acceleration has been developed and successfully tested. The first stage is a combination of a hydrogen pellet generator and a gas gun, which is responsible for injecting a medium-velocity hydrogen pellet into the second-stage railgun through a coupling piece. As the pellet enters the railgun, a specially designed arc-initiation scheme electrically breaks down the propellant gas which has followed the pellet from the gas gun into the railgun, thus forming a conducting plasma-arc armature immediately behind the pellet. This arc formation event coincides with the triggering of the mainmore »« less

Development and study of a 3. 2-mm-diameter, 1. 2-m-long two-stage plasma-arc-driven railgun for hypervelocity hydrogen pellet injection

Technical Report Zhang, D.; Kim, K.

A detailed description of a prototype, fuseless, plasma-arc-driven, two-stage railgun system with a 1.2-m-long railgun barrel and a 3.2-mm-diameter circular bore is presented, along with the preliminary results indicating its capabilities and limitations. A hydrogen pellet generator, which has a straight-tube configuration and which is also operated as a gas gun, is employed as the first stage of the two-stage acceleration system. The design details of this preacceleration system and the results illustrating its performance are first presented. The second-stage accelerator which acts as a booster accelerator, is a fuseless plasma-arc-driven railgun, and constitutes the core of the entire two-stagemore »« less
