The performance of a reversible helical electromagnetic launcher (RHEML) is reported and discussed. The results demonstrate the feasibility of using the RHEML as an electrically programmable shock tester (EPST). The data show that the reversible heli

A new electromagnetic-launcher (EML) performance parameter called the specific force is presented and analyzed in this paper. The specific force is the second derivative of the EML's force equation with respect to current and represents the force gen

Properly designed augmented railguns (ARGs) can operate at significantly lower currents and higher efficiency than conventional non-ARGs. This paper analyzes the performance of a two-turn and a three-turn ARG showing the design parameters that are ne

The mechanisms and predictors of insulator degradation and erosion by pulsed high-current surface discharges are presented and discussed. Erosion and degradation depend on the insulator material, the electrode material, the ambient gas, and the prese

While Grover's tabular method to compute the mutual inductance of coaxial single-layer coils is convenient and fast when implemented on computer, its use has mostly been restricted to zeroth- and first-order calculations, since its accuracy is not we

Helical electromagnetic launchers (HEMLs) can operate at significantly lower currents and higher efficiency in comparison to conventional railgun and induction coilgun launchers. The HEML's versatility is due, in part, to its large inductance gradien

The maximum theoretical efficiency of constant inductance gradient electromagnetic launchers (EMLs) is analyzed and discussed. The maximum theoretical efficiency is a parameter needed to calculate the EML's efficiency. Constant inductance gradient EM

We present a characterization of contact velocity skin effect (VSEC), which is a major velocity- and efficiency-limiting effect at a railgun's sliding contact. Despite enormous contact forces, the armature remains separated from the rail by a thin la

The principal advantages of the sequentially fired pulse forming network (SFPFN) over its passive analog are its utility in both linear and nonlinear load applications. Operation of the SFPFN consists of charging multiple capacitor banks to different
