Procedure for Surveying a Station in the U.S. Army Research Laboratory Transonic Experimental Facility Spark Shadowgraph Range
Abstract
The indoor instrumented spark range at the U.S. Army Research Laboratory Transonic Experimental Facility was designed for firing various-caliber projectiles to establish their free-flight characteristics. The in-flight position and orientation of the projectile is measured using 25 orthogonal pairs of spark photography stations, providing a set of shadowgraphs. An intrinsic part of the spark range instrumentation is the complex fiducial system that resides within the facility. This report presents the step-by-step method used to survey one of the 25 orthogonal fiducial stations using specialized equipment and techniques. Such a survey may be conducted to measure and record the position of an existing fiducial bead, reattach a bead to an existing fiducial wire, or be part of a larger effort to replace a broken or damaged fiducial wire or other system component.
