Abstract
A windmill rotor of the front-runner type and airfoil type wind blades therefor in which the blade tips have a longitudinally forwardly curved configuration. The curvature solves the problem of inward flexure of the blade in strong wind conditions, without requiring modification of the manner in which the rotor as a whole is mounted in order to avoid having the blade strike the windmill tower under such strong wind conditions.
