A Pulse-Forming Network Design for Electrothermal-Chemical (ETC) Combustion Characterization of Solid Propellants.
Abstract
The combustion of solid propellants subjected to plasma augmentation has been studied with a 300-kJ maximum stored energy Pulse-Forming Network (PFN) in the range of 1 KJ/g of electrical energy over a 1.2-ms pulse length. A closed chamber vessel is used for the combustion of these solid propellants in which the plasma is injected via a plasma generator. Since the need to characterize the effects of plasma augmentation on propellant combustion may require a greater pulse length than the 1.2 ms initially provided by the PFN used at the U.S. Army Research Laboratory (ARL), a PFN upgrade providing a 2.4-ms pulse length with a 400-kJ maximum stored energy was implemented. When operated at 5 to 7% of the maximum stored energy, the PFN pr6vides augmentation in the range of 1 kJ/g of propellant. Calculations, design, and fabrication are detailed. Also discussed are plasma generator modifications dictated by the increase in pulse length and energy input needed for test firings.
