Abstract

The increasing use of electrical energy is inversely proportional to the diminishing fossil energy sources. New and Renewable Energy  is one of the alternative energy that is being developed now. One of the energy used in the utilization of new and renewable energy is wind energy. In this study, we will discuss the manufacture of blades made from Expanded Polystyrene (EPS) Foam which is intended for wind turbines at low wind speeds. The use of this material is used and is able to form a blade with a weight of ± 300gram. This blade uses an Inverse Tapper type blade, which is a blade with an enlarged geometry at the tip, this geometry has a large surface so that it can receive more wind so that it can rotate at low wind speeds. The design and manufacture of blades is carried out using Aeolus ASP software which is open source on several analysis features and serves to determine the performance of the blades as well as to analyze aerodynamics and optimization of the shape of the blades designed to use Blade Element Momentum (BEM). This blade is capable of producing a voltage of 12.09 V. In the process of making the blade using wire cut to create geometry with National Advisory Committee for National Aeronautics (NACA) 4412 airfoil. The blade uses layers of balsa wood and monocote plastic sheets, and uses wood plywood as the base of the blade.

Abstract

In the manufacture of wind turbines, there are several parameters that are taken into account, namely the wind speed in the area to be installed. The wind speed in Indonesia ranges from 3m/s – 11m/s, so it is quite difficult to implement a macro-scale wind turbine and the facilities are still inadequate. So this design is a design to make a micro-scale wind turbine that adapts to the characteristics of wind speed in Indonesia. In this design, a blade with the Inverse Tapper type is made which is a blade type with an enlarged shape to the end to get a large sweep at the end of the blade and produce a lift force that is greater than the drag force on the blade so that it can rotate the blade. In the design of this blade, material changes are also made, generally the material used in the blade is made of wood, fiber, and aluminum. In this design, a material made of styrofoam is used, this is to make the mass of the blade lighter and make the blade able to rotate at the smallest wind speed. In this design, the maximum power obtained is 553 watts at 668 rounds of blade rotations . Keywords : Airfoil, Inverse Blade, Cl/Cd, Styrofoam.
