With conventional windmills the wing blades used have a certain resilient flexability which, in connection with "front runners", implies that the wings in strong wind are bent inwardly towards the mill tower, i.e. the wing rotor should be placed with a required safety spacing from the mill tower. An associated forward displacement of the entire rotor involves high costs and has already been avoided in various unsuccessful manners. The invention provides for an improved solution of the problem in disclosing that the wing blades, per se, are designated with such a forwardly curved configuration that the wing tips, when the wings are mounted in a conventional manner on the wing hub, will be located with increased spacing from the side of the tower.
