Abstract: Osculating outer cone waverider design are mainly focused in the present osculating waverider design methods. Osculating inwardturning cone (OIC) methods are developed in this paper. Internalconical flow A (ICFA) is used as stream tracing flow field in OIC waverider.Inlet capture curve (ICC) and front capture tube (FCT) are defined first andthe OIC waverider is then generated by using Osculating aixymmtric methodand streamline tracing technique. The designed OIC waverider's flow fieldsand aerodynamic characteristics are numerically simulated under designconditions and the numerical simulation results are compared withtheoretical results. Both theoretical and numerical results are consistentwith each other well.
