Evaluation of Component Buildup Methods for Missile Aerodynamic Predictions

This paper presents an evaluation of component buildup aerodynamic methods for missile design. The methods presented define the methodology which could be incorporated into a handbook and computer program for missile aerodynamic predictions. Selected criteria and recommended aerodynamic prediction methods for isolated components, interference, inlet/airframe interactions, vortices, and propulsion system effects are presented for use in conceptual or preliminary design. The methods investigated include theoretical, semiempirical, and empirical techniques presently used in industry. Although many methods are available, gaps in methodology do exist and are identified.
