The lateral axis wind turbine comprises of a pair of oppositely placed hubs in combination of plurality of extended radial arms symmetrically projected out wards and fitted on bearings to the central shaft. The turbine blades are pivoted between each extended pair of arms and are having the freedom to swing around their own axes and around the common axis of central shaft.

The central shaft comprises of a cam profile over which lever arms of turbine blades could engage during its working cycle. In operation, the streaming wind, forces the blade along the direction of wind while the extended lever arm turn towards the cam profile fitted around the central shaft. During power stroke the cam profile prevents the blade swing any further, by giving leverage to the turbine blade to force pivot axis of the blade turn forward along with the wind direction. Lever arms terminate engagement with cam profile during idle stroke and revolve around central axis and come back to initial position during next phase of the working cycle. Passive yaw control is archived by fixing flat plates, on the surface of rotating radial arms perpendicular to main shaft axis. Orienting the turbine blades in the wind direction is achieved by mounting rotatably on the towering structure of the wind mill.

The turbine design has low center of gravity and easy to assemble. It can turn by rainfall and snowfall as well.

This design doesn't involve complicated manufacture for its turbine blade shapes. Therefore it can fabricate with scraps and locally available materials.p>Turbine control is used for better performance. Further it helps structural stability and optimum output. The yaw system can align the wind turbine in parallel with wind direction.

A passive yaw control systems is applied using the wind force to turn the rotor towards the wind. An active yaw system also could be applied to a commercial scale wind turbines.

Present wind turbines, turbine blade area limit to a small fraction of the swept area. This problem has overcome by the present wind turbine by turning the blades in a lateral direction of the blowing wind, while leaving the blades to face full force of the wind.

Present wind turbines sweeps a circular area of the sweeping wind. Lateral axis wind turbine sweeps a square area of the wind flow to generate more power.
