Design and Fabrication and Testing of a Low Speed Wind Turbine Generator Using Tapered Type Rotor Blade Made from Fibre Reinforced Plastic

Abstract: This study fabricated a three bladed wind turbine of 0.6 m rotor diameter. The blade was divided into ten sections and shape derived from the blade element and momentum theory with two linearization points at 70% and 90%.. Other design values chosen were; clark Y as the airfoil type, 2.5 as tip speed ratio, 1.1 as lift drag ratio, design angle of attack of 8 o . The rotor blades were fabricated using two layers of fibre reinforced plastic and 2% hardenning on resin. The power coefficient of the turbine was tes… Show more

“…The design values included; the design tip speed ratio is λ d =2.5, number of blade is three, and a rotor with tapered blades in which the chord length increases from the root towards the tip, lift-drad coefficients' ratio (Cl/Cd) ratio 1.1 and rotational speed of 750 rpm. Saoke (2014) found exciting results on the performance of this turbine in the wind tunnel, the coefficient of power was found as 0.29. The study recommends more work to be done on the blade geometry to optimize its Cp value.…”

“…The gears are made of two discs as shown in figure (5), one of which is large with a disk of 164 sprockets and is bolted to the spindle, and the small disc is attached to the generator spindle of the number of sprockets (9). The sprockets are designed to be easy to engage with each other to transfer mechanical energy from rotor to generator to generate electric power and the figure below shows how the gears are designed.…”
