Evaluation of Electromagnetic and Electrothermal Launchers for the BRL Advanced Test Facility
Abstract
Optimum designs have been developed for three types of electric launchers that can be used for conducting terminal ballistic research. BRL specified the operational requirements, viz., to accelerate penetrators having a mass in the 60-200 g range and a length-to-diameter ratio in the 10-40 range to velocities in the 2.5-3.5 km/s range. Capacitor-driven electromagnetic launchers (EMLs), homopolar-generator-driven EMLs, and capacitor-driven electrothermal launchers have been evaluated and compared on the basis of technical risks and capital costs. A capacitor-driven EML is recommended as the best option for meeting BRL's requirements. Based on the design of the preferred launcher option, a one-year commissioning/test (C/T) program has been defined. The C/T program addresses the technical issues that can be identified that impact on facility performance, reliability and cost of operation. The resolution of these issues by the conclusion of the C/T Program will allow routine operation of the facility for terminal ballistic research to commence. At that time, the BRL team should thoroughly understand the operation and maintenance of the advanced gun facility. Keywords: Electromagnetic guns; Army research laboratories; Army test facilities.
