LITEREATURE REVIEW ON THE GLOBAL WIND TURBINE PROPELLER TYPES

Abstract

The global energy crisis and the urgency of climate change mitigation, encourage the use of renewable energy, one of which is wind energy. The efficiency of the conversion of wind energy into electricity is very dependent on the design of the wind turbine propeller. This study aims to conduct a comprehensive literature study of various types of wind turbine propellers that have been developed and used globally, especially in the context of small-scale turbines for household needs. The method used is descriptive-qualitative literature study by examining various scientific sources, such as international journals, technical books, and reports of energy institutions. The results of the study show that there are several main types of propellers, namely Horizontal Axis Wind Turbine (HAWT), Vertical Axis Wind Turbine (VAWT), multi-blade, and Helical Blade, each with characteristics Aerodynamics, excellence, and its own limitations. The analysis also shows that the design of the propeller is efficient, simple, and low-cost is needed for the use of wind energy on a household scale, especially in tropical regions such as Indonesia. This research is expected to be a reference for the development of a mini wind turbine that is applicable, affordable, and sustainable.
