Component intersections are a persistent challenge in aerodynamic design. In this work, we present a method based on inverse distance warping to deform a fillet between two components for the minimum drag design. We show that this is tractable within gradient-based aerodynamic shape optimization and results in lower drag designs than those optimized without changing the intersection region.
