The focus of this paper is to provide the technical background, summary and implementation of a Joint GTRI, ARL and DARPA effort to explore the feasibility of producing steering forces on a spinning projectile using micro-adaptive flow control MAFC. The paper discusses the theoretical foundation for the non-linear flow control mechanism, the multidisciplinary modeling technology developed, the flight control technology required to enable the MAFC on spinning projectiles, the design of the flight test and validation hardware, and the results of the closed-loop flight test. The closed-loop tests clearly indicate that MAFC can be used as a control technology on a non-linear spinning projectile and can be extended to other subsonic munitions.
