A Cambered Body Method for Missile Datcom

Abstract

*# A method for analyzing cambered bodies has been incorporated into Missile Datcom. Existing methods based on mean line theory, slender body theory, viscous crossflow theory were assessed. They were compared with wind tunnel data from subsonic to supersonic speeds for cambered bodies with axi-symmetric cross-sections. The comparison cases consisted of three configurations with discrete camber changes (deflectable nose missile) and twelve configurations with continuous camber changes. A combination of slender body and viscous crossflow theory was found to provide the best agreement with experimental data. Nomenclature
