ABSTRACT OF THE DISCLOSURE A wind mill comprising a tower construction carrying on its top in turnable arrangement a wind turbine with a two bladed or a three bladed propeller attached to a substantially horizontal axis, plate strip members being mounted on the tower in helical course with their free edges extending from the tower. The invention solves the problem of reducing the detrimental effect on the propeller- of towers which at their top in turnable arrangement carry a wind turbine with a two bladed or a three bladed propeller mounted on a substantially horizontal axis. The improved wind mill reduces the risk of a fatigue fracture in the roots of the propeller and in the hub and also reduces wear on the bearings of the propeller axis.
