Missile Datcom is an industry-standard tool used for predicting the aerodynamic stability and control performance of conventional missile configurations. In August 2008, the US Air Force Research Laboratory (AFRL) and the US Army Aviation and Missile Research, Development, and Engineering Center (AMRDEC) released the 8/08 version of the Missile Datcom code. Among the major changes introduced were: 1) significant revisions to the axial force prediction methodology for bodies with blunted, truncated, and low fineness ratio noses and 2) an additional capability that permits the user to specify angular orientations for body protuberances, thereby allowing the calculation of incremental pitching and/or yawing moments resulting from protuberance drag. This paper documents the process utilized in developing, implementing, and validating the updated methods in the 8/08 release of Missile Datcom, and includes comparisons with experimental and computational fluid dynamics data.
