A wind powered electrical generating system having a suitable shaped aerodynamic duct or shroud within which a wind turbine having a fixed pitch blade is mounted, as by means of a stator means at the inlet of the duct or shroud with the stator means including mechanism for varying their effective angle of attack with regard to the approaching wind so as to provide the desired swirling approach of the wind to the turbine therebehind in achieving the desired torque and speed of shafting from the turbine to generator driven by the turbine in maintaining constant phase and frequency of the electrical output wherein the duct or shroud is mounted by a tower or shaft that will permit the cocking of the structure into the wind.
