The full-scale development (FSD) program of a new store includes determination of the aerodynamic configuration, mapping of the aerodynamic characteristics and determination of the release envelope. For particularly concerning A/C-store geometry the Risk-Reduction Phase (RR) of the FSD includes a preliminary separation analysis. Usually, this preliminary analysis is based on Captive Trajectory System (CTS) tests. The CTS technique may yield inadequate data for cases with very close distances between store and A/C.A new preliminary store separation analysis method is suggested, RR6DS, a 6 degrees of freedom (6DOF) simulation based on a few Captive Wind-Tunnel tests and free-stream aerodynamics. This new method was successfully applied for the Smart Precise Impact and Cost-Effective guidance kit (SPICE) development program, to determine its aerodynamic configuration.The RR6DS method is a quick, cost-effective and approximate version of the full simulative technique that includes grid tests. This paper describes the RR6DS method and presents a comparison between the CTS tests and the 6DOF simulation results. c m Cm« Cn Q CX C Y C z H •yy
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
