Abstract : The investigation of the applicability of a higher order panel method code to the aerodynamic analysis of missile configurations is the object of the paper. In a cooperative work between MBB and ONERA, the HISSS code - developed by MBB for the analysis of attached, subsonic and supersonic flow about complex aircraft configurations - has been used for calculating a large variety of different missile geometries, including classical configurations, non-circular bodies an air-breathing configurations. Accuracy and limitations of the present theoretical approach are evaluated and discussed by comparison of calculated results with wind tunnel data available at ONERA. It is concluded that the method can be successfully used for the analysis of very complex missile geometries at both subsonic and supersonic Mach numbers, provided that the flow conditions prevent violation of the underlying linearized potential theory.
