Abstract : An approximate flow field technique is developed for the prediction of inviscid aerodynamic characteristics of re-entry vehicles with asymmetric nose geometries at angle of attack and/or sideslip. The subsonic flow region on the nose is approximated using a correlation for surface pressures and iterating on the shock position to satisfy mass continuity. The axisymmetric frustum is computed using the exact three-dimensional inviscid equations, explicitly treating crossflow effects. (Author)
