Title:
BIONIC AIRFOIL BLADE
Document Type and Number:
WIPO Patent Application WO/2020/237850
Kind Code:
A1
Abstract:
A bionic airfoil blade. A profile curve of the bionic airfoil blade comprises a bionic airfoil blade back curve and a bionic airfoil blade abdominal curve. An included angle α formed by the bionic airfoil blade back curve and the bionic airfoil blade abdominal curve at a leading edge is 14.43, and the included angle β formed at a trailing edge is 6.42. Also disclosed is a design method for the bionic airfoil blade. The bionic airfoil blade has good lift-drag characteristics and hydraulic performance. The method can design bionic airfoils with different maximum thicknesses, and is high in practicability.
