Design, Fabrication and Performance Analysis of Loopwing Horizontal Axis Wind Turbine

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
