Measurement Techniques for Electrothermal-Chemical Gun Diagnostics
Abstract
Methods of acquiring data, including pressures, load current and voltage, and 'crow-bar' diode current and voltage with a minimum of electrical noise in electrothermal-chemical (ETC) ballistic and combustion experiments are described. Measurements are performed in a 30-mm ETC gun facility that is driven by a 130-kJ (maximum) pulsed-power supply and a 50-cm(3) closed chamber facility using a 300-kJ power supply, both of which are located at the U.S. Army Research Laboratory. Strict attention is devoted to grounding of measurement and data- recording devices, as well as in shielding of measurement electronics, data lines, and high-power modulator components with 'Faraday' enclosures. The use of ferrite rings on data lines and 60-Hz power lines is frequent, and fiber optical links are used for electrical isolation between data recording equipment and high-voltage components. The experimental arrangement and resulting data are presented, and comments and conclusions are included.
