Designing mini model of wind turbine blades based on Horizontal Axis Wind Turbine model
Abstract
Wind turbine is a rotating machine which converts the kinetic energy in wind into
mechanical energy then is converts to electrical energy using electrical generator. A
prototype development of Horizontal Axis Wind Turbine is produce with the purpose to
design a mini model of wind turbine blades based on Horizontal Axis Wind Turbine model
and to build mini model of Horizontal Axis Wind Turbine that can produce electricity. This
project consists of several processes starting from designing process, material selection
installation and testing. Airplane winglet wing and propeller has been choosing as wind
turbine blade design. Two type of testing is used to run Horizontal Axis Wind Turbine
model; Output voltage testing and L.E.D testing. Higher number of blade produce more
output voltage. The optimum angle to harvest kinetic energy from wind source in this
project is 45°. The comparison between two designs of wind turbine blades shows that
Twist blade is a better design compare to Winglet blade. For overall, this project is
successful and able to produce electricity from wind source.
