Abstract
A new 1kW wind turbine blade was designed for optimal performance in low wind speed areas with the use of computer software, Propid. It consists of a newly designed airfoil for good tolerance to low Reynolds numbers. It also shows low drag, compared to other wind turbine airfoils, when contaminated in the form of bugs or dirt.
Structural design and analysis were done with Ansys software in order to optimize the composite material strength to weight ratios. The moulds for manufacturing of the blades were CNC-machined. The G-Codes for the process were generated by an in-house-written 3D computer program to ensure high accuracy of the airfoil and planform shape.
Compared to other locally manufactured blades, the new blades have superior performance in low wind speeds. This enables wind turbines to generate adequate power at previously unsuitable areas.
