Abstract
The main goal of our research is to design a windmill to withdraw and pump groundwater in agricultural areas where delivering electrical current is expensive and requires high voltage. We designed, manufactured, studied and described horizontal axis wind turbines, as the system was designed locally. It is considered one of the best options for low-speed winds. The turbine contains ten blades, the length of each blade is 1.2 meters, and the turbine area is 4,524 square meters, with the height of the wind turbine tower reaching 8 meters. The gearbox contains 2 gears, one of which is a small one consisting of 24 teeth called Driver and the large gear contains 120 teeth called Driving, where the conversion ratio is 5:1 in order to obtain a lower speed and greater torque. The best characterization of the system was studied at low wind speeds, as the turbine power depends on the wind speed. It is suitable for use in the Qayyarah district during the summer. The cost of this project is very low compared to other projects that are used to pump water. It is also considered important for reducing desertification and increasing investment.
