A novel method for optimal design of hydrodynamic performance of bionic propeller with a deformable leading edge is proposed. Based on the bionics principle and method of parameterized modeling. the fore-fin concave-convex structure of humpback whales is applied to the propeller leading edge. the leading edge in the propeller to meet flow region according to the exponential decay curv... https://www.kwangleetkd.com/product-category/gift-card/
