Innovative Technologies and Techniques for In-Situ Test and Evaluation of Small Caliber Munitions

application of microadaptive flow control techniques to small caliber munitions. This article discusses innovative techniques and technologies created in pursuit of the development, test, and evaluation of this new control technology. Tools developed include the use of g-hardened sensors, processing and actuator control electronics in 25 mm and 40 mm munitions. Inertial measurement units meeting all survival, packaging, and power requirements were designed and implemented using low-cost commercial off-the-shelf sensors including micro-electromechanical systems accelerometers and rate sensors and solid state magnetometers. Using resources integrated on the processor, flight data were recorded and stored for post-flight retrieval. An innovative projectile soft capture system allowed the projectiles to be safely recovered and reused multiple times. Data analysis techniques were extended to evaluate the in-flight performance of the microadaptive flow control technology. Further, the data served as a diagnostic tool to compare system flight performance with ground-based tests. Key words: dynamic engagement test environment; guidance and control; integrated electronics; Maneuverable munitions; microadaptive flow control technology; SCORPI-ON Program; spinning projectiles. T he Future Force Concept for the U.S. Army clearly outlines a strategy for operational scenarios that feature com-bined-arms operations in a multi-threat, dynamic engagement environ-ment. Precision small to medium caliber munitions are integral and necessary elements of this strategy. To meet this vision, innovative techniques and technolo-gies are needed for both the realization and test and evaluation of small, spinning, guided projectiles.
