This work implements a coupled viscous-inviscid interaction method between a VLM and RANS to develop a medium fidelity aerodynamic analysis approach for aerodynamic design. The method is differentiated using a coupled adjoint method for use in gradient-based design optimization and MDO frameworks. We demonstrate the approach for optimizing a cruise-slotted wing.
