This contribution reports about a generalization of the successful Osculating Cones method for designing waverider forebodies and inlets, to an Oscillating Axisymmetry (OA) concept for obtaining shapes with higher volumetric efficiency and flow quality control on the inlet plane. The approach is based on an inverse axisynnetric method of characteristics which through the OA concept allows the construction of 3D flows as a solution to the 3D Euler equation within a few seconds on a workstation.
