A wind turbine is a device that is able to convert wind energy into mechanical energy, then converted into electrical energy through a turbine generator. Wind turbines that rotate on a horizontal axis are called horizontal axis wind turbines (TASH) and those that rotate on a vertical axis are called vertical axis wind turbines (TASV). The efficiency of horizontal axis wind turbines can be increased to obtain maximum power coefficient. The aim of this research is to simulate a wind tunnel trainer kit that has been designed and made. Can find out the shape of a miniature wind turbine model and the maximum rotation produced during testing. This research method is to analyze the performance of wind turbines so that a Horizontal Axis Wind Turbine (TASH) simulation design is carried out with variations in the number of blades of 3, 5, 8, angle variations of 0°, 5° and variations in wind speed as well as analyzing the effective performance efficiency produced by the wind turbine. the. Measurement parameters are analyzed from Power, Torque and Thrust. Based on the results of the analysis and design that has been carried out, the wind turbine tested at the average wind speed in Riau Island, namely 6.13 m/s and a rotational speed of 325.27 rpm, found that the most efficient wind turbine is with 8 blades with a power of 325.27 rpm. watts, rotor torque 0.0170 Nm and thrust 0.74 N with a pitch angle of 5°. In calculating the greatest efficiency produced by wind speed, the best turbine efficiency was obtained at a speed of 1.972 m/s with a wind rotation speed of 104.67 rpm, turbine power of 0.27 watts and an efficiency of 56.6%. Based on the simulation results, the highest Reynolds number is found in 3 turbine blades.
