Optimization Design of New Bionic Propeller

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 acc
