Electronic and Fiber-Optic Applications in Pulsed Power Networks

摘要

The electrothermal-chemical (ETC) gun program at Aberdeen Proving Ground, MD,utilizes pulse-forming networks (PFN) to deliver electrical energy at specific energy profiles. This energy, when injected through a 'capillary' chamber as a superheated jet, causes the combustion of propellants or working fluids. The possibility of attaining a greater pressure gain by delay-triggering the plasma injection from the conventional electric match propellant ignition (pressure raise), using an electronic voltage/pressure sensor and time delay generator, is discussed. The high electrical energy level involved in these PFN operations requires the use of a fiber-optic control system, which is also discussed. Fiber optics, Pulse-forming networks, Firing circuits.
