ABSTRACT

This project presents the design, modelling and simulation of a wind turbine blade based on assumed local wind speed of 7m/s with a rotor performance of 10KW. These key values were plugged into QBLADE to design and model the blade using Blade Element Momentum (BEM) Theory.A MA TLAB program was developed to use (BEM) in designing a model of Horizontal—Axis Wind Turbine (HA WT,). NAGAOOI2 airjbil was selected Jbr the design of the wind turbine blade. The designed blade was also drawn and stress analysis conducted using SOLID WORKS. During optimization it was observed that the designed blade can operate optimally on increasing the wind speed from 7m/s to 12m/s, the optimal power generated was 53.528KW and the power value increases due the increase in air-velocity impact on the wind turbine blade. The designed blade had a coefficient ofpower of 0.3596 which falls within Beltz limit (0.25 — 0.40). The designed blade was seen to fail at I000N/m2.
