Hydrofoil is the direct component to generate thrust for underwater glider. It is significant to improve propulsion efficiency of hydrofoil. This study optimizes the shape of a hydrofoil using Free-Form Deformation (FFD) parametric approach and Surrogate-based Optimization (SBO) algorithm. https://www.bekindtopets.com/hot-mega-BioSentry-BioPhene-Spray-Disinfectant-15-5-oz-best-find/
