The Devil is in the Details: How to Build Your Own Continuous Adjoint Airfoil Inverse-Design Tool

The continuous adjoint (CA) technique for optimization and/or inverse-design of aerodynamic components has seen nearly 30 years of documented success in academia. The benefits of using CA versus a direct sensitivity analysis are shown repeatedly in the literature. However, the use of CA in industry is relatively unheard-of. The sparseness of industry contributions to the field may be attributed to the tediousness of the derivation and/or to difficulties in implementation due to the lack of well-documented adjoint numerical methods. This presentation will briefly address some of the roadblocks the investigator experienced in building a continuous adjoint inverse-design tool from first principals. The derivation process for the continuous adjoint equations and the resulting equation set will be described. In addition, the numerical methods used during implementation as well as some of the pitfalls to avoid will be discussed. Finally, examples of airfoil inverse designs will be given.
