2. ABSTRACT: Vertical – axis (Horizontal Turbine) rotors can be either drag-or lift-based. The cup anemometer is an example of a drag-based, vertical axis wind device. The drag on a cup is greater when its concave side faces the wind which causes the device to rotate.   Lift also plays a small part: the cups crossing the wind experience a small lift because their convex surfaces deflect the wind and causes a pressure reduction. The main virtue of the cup anemometer is that it tends to rotate within a narrow range of TSRS under all conditions, so its rotational speed is closely proportional to wind speed.

3. INTRODUCTION However, it can not carry a load with any efficiency; it has never been constructed on a large scale for use as a wind turbine. The Savonius rotor works on a principle similar to that of the cup anemometer but is adopted to produce shaft power. It also takes advantage of the lift generated as the curved outer surfaces of its scoops cross the air flow. There are also a variety of so-called Panamones; there are pure drag devices, in which one side of the rotor carries blades or sails square to the wind, while other side produces reducing drag by shielding or furling the blades. Because drag devices tend to run at TSR below unity (since their tips can not readily travel faster than the wind), they are inevitably less efficient than lift-dependent devices. In addition, their high solidity makes them more material-intensive in relation to the wind area ‘seen’ by the rotor.

6. SHEET METAL: The term “sheet metal” refers to  any metal that can be formed into flat pieces of varying thicknesses . Thick metals are called plate. Metals used in the sheet metal industry include cold rolled steel, mild steel, stainless steel, tin, nickel, titanium, aluminum, brass, and copper.

7. DYNAMO: A dynamo is a type of electrical generator that is used to create a conducting current with the help of a commutator. A dynamo used the laws of electromagnetism to create a direct conducting current or electric power from the rotation of the coil .

8. BATTERY: A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

9. FRAME:   something composed of parts fitted together and united. : the underlying constructional system or structure that gives shape or strength (as to a building) : a frame dwelling. 3. : an open case or structure made for admitting, enclosing, or supporting something.

10. SHAFT: That rotates and transmits power from a driving device, such as a motor or engine, Throu The term shaft usually refers to a component of circular cross section gh a machine. Shafts can carry gears, pulleys, and sprockets to transmit rotary motion and power via mating gears, belts, and chains .

11. WORKING PRINCIPLE A horizontal wind turbine has currently been modernized from the traditional windmill designs that have been around for many centuries. A nacelle installed perpendicular to the turbine tower and horizontal In terms of the ground shows the name of the turbine. Most common models for drawing energy from wind, the horizontal wind turbines offer a great amount of advantages . The core components of a horizontal wind turbine are as shown below: - The main rotor shaft - The electrical generator - The gearbox to increase the rotation speed of the blades - Turbine blades, with stiffness to avoid contacting the post A wind vane is used to point the turbines, while a wind sensor is implemented for a large horizontal wind turbine
