Abstract

Until the present date, free flight spark ranges have used conventional film technology for recording the position-attitude histories of projectiles as they traversed the instrumented ranges. Film solutions provided precise position-attitude data, but not without limitations. Film requires substantial range set-up, processing, and analysis time. Days or weeks could pass before a given experiment would have its data reduced for interpolation. Such time delay, and its attendant inefficiencies, could be greatly reduced by using a CCD camera of proper resolution operating in conjunction with a compatible data collection system. This capability would create an electronic shadowgraph system. The purpose of this paper is to describe the camera and data collection system first tested at the free-flight range at Eglin Air Force Base in February of 1992.
