The design of hypersonic vehicles and hypersonic propulsion systems is a challenging endeavor.Affordable computational power has made CFD more accessible, including for optimization related tasks. Adjoint optimization methods that were previously in the realm of research are now available in commercial softwares like STAR-CCM+. This work explores the use of adjoint-based optimization with STARCCM+ for hypersonic vehicle design in two case studies on external and internal hypersonic flows. For the external aerodynamics, a waverider geometry is optimized for lift over drag while considering particular constraints. In the internal flow case, mixing is improved inside a hydrogen scramjet geometry using adjoint CFD. Both the advantages and the limitations of adjoint-based optimization are evaluated.
