The Aeroballistic Research Facility is one of several free-flight aerodynamic research facilities in the world and has gained a reputation as one of the most accurately instrumented. This facility was developed for the exterior ballistic testing of gyroscopically stabilized fin stabilized or mass stabilized projectiles. Such testing includes bullets missiles and subscale aircraft configurations. The primary source of data for this type of facility is the trajectory information derived from orthogonal pairs of shadowgraph film cameras. The loading unloading processing digitizing and off-line analysis of the film data is extremely costly and time consuming. The unavailability of even unreduced images for subjective evaluation often means delays of days between experiments. In this paper we describe evaluation of an advanced still video system as the baseline for development of an integrated real-time electronic shadowgraph to replace the film cameras for normal range operations. 1.
