Abstract:

This research presents the design, fabrication and performance analysis of loopwing horizontal axis wind turbine. Among the many types of wind turbine, most of them failed in efficiency because of the higher rotating speed required in other conventional horizontal axis wind turbine. Another vertical axis wind turbine suffers unbalance torque between the right and left side which causes vibration. Loopwing horizontal axis wind turbine is operated at low rotating speed without reducing energy efficiency. There is no vortex discharge and noise because loopwing horizontal axis wind turbine has strip ribbons as its blade tip portion ends in a loop shape. Loopwing horizontal axis wind turbine blade is designed by the using of basic design formula such as angular momentum theory, blade element theory. The NASA SC(2)-0402 is chosen as  the loopwing horizontal axis wind turbine blade profile by comparing it with a similar airfoil shape from the results of Profili Software. The model of loopwing horizontal axis wind turbine is drawn by using Solidworks 2018. Performance testing is carried out on the roof of Main-Building at Mandalay Technological University. The wind turbine hub is placed 14.6 m above the ground. The material of loop type blade wind turbine is stainless steel.  The performance analysis of loopwing horizontal axis wind turbine is emphasized in this research. This loop type blade wind turbine can be started wind speed at 1.5m/s and cut-out wind speed at 12m/s.  Electrical power output can be produced by about 100 W by the following horizontal axis wind generator at rated wind speed  6m/s. Rotor diameter is 1.5m and the no. of the blade is three and the tip speed ratio is 5.
