Abstract

A wind rotor member (10) comprises a central hub portion (14, 15) by which it may be mounted for rotary movement around a substantially horizontal axis, and a number of rotor blades (16) which are secured to said hub portion (14, 15) in stationary positions relatively thereto and which extend in generally radial outward directions from the hub portion. In order to enable operation within a very wide range of wind speeds, each rotor blade has a larger blade angle (vC) at its outer end than at its inner end (vA).
