A three-dimensional blunt body inverse technique is formulated in terms of two-component stream functions in the spirit of the Ferri, Vaglio Laurin axisymmetric blunt body method. In a sim ilar manner to the axisymmetric case, transforma tions are found that reduce the elliptic asymmet ric shocklayer to a transformed space in which shock, streamlines or the intersections of stream surfaces, body, and sonic surface are a priori known, so that numerical analysis proce dures are considerably simplified. Provided three equations in the three velocity components of the transsformed space are numerically solved, then inverse transformations are given so that the corresponding velocities, pressure, and density at a point in the physical space may be deter mined. The class of given shocks considered are portions of prolate ellipsoids in the physical space.
