The present paper aims to describe the potential of the adjoint technique for aerodynamic shape optimization. After a brief description of the continuous adjoint formulation and the aerodynamic optimization process developed at the DLR, specific requirements for an optimization framework combined with the adjoint technique are introduced. The drag reduction at constant lift and pitching moment for the RAE2822 airfoil in transonic flow is then presented as validation case. An extension to multi-point optimization demonstrates the capability of the framework to solve more complex problems. Finally, the wing-body optimization of a supersonic commercial aircraft confirms the flexibility of the framework and the efficiency of the adjoint technique.
