Well-crystallized segmented graphite nanofibers were prepared by pyrolysis of acetylene at 600–800°C using foam Ni catalyst. Transmission electron microscopy indicates that this kind of nanofiber looks like a linear array of lens-like segments wit

In the linear induction launcher (LIL), the barrel is divided into sections, and each one is energized in polyphase fashion by discharging a capacitor bank through the drive coils. The capacitor voltages and the frequency of the currents in the drive

A computer model, previously validated, was used to study the performance of an experimental three-phase launcher energized by a capacitor bank and designed to impart to a 137 gram projectile a muzzle velocity of 500 m/s: (1) the build-up of the trav

The performance of a two-section three-phase capacitor-driven LIL is analyzed by means of a computer simulation code which is based on the transient behavior of a lumped circuit model representing the gun. Initially, to design this launcher, to selec

This paper describes the design, construction, and testing of a 500 m/s linear induction launcher (LIL). This name was derived from its principle of operation which is similar to that of the classical induction motor. Various theoretical models and c
