Synopsis

Blades happen to be the most critical part of the Wind Turbine and careful examination goes into the modelling and analysis of blades to increase the overall efficiency of the Wind Turbine. In the present work we design a wind turbine blade using the coordinates of the airfoil NACA 4415. The materials used are Aluminium and E-glass fiber/ epoxy. We perform the required analysis using various force and pressure requirements to analyze the stability of the blade. Vibration analysis is performed using Finite Element Method using ANSYS solver. Further, we use various materials to assess the strength of the blade along with various pre-twist angles to understand and assess our model. This is done to understand our model and pave way for further optimization, if any. In the present work we have plotted graphs for natural frequencies during free vibration, and of maximum deformation and maximum stress during application of static loads in Mechanical APDL software. The effect of Pre-twist on the natural frequencies of the Metallic blade is investigated. The vibration analysis and material properties are applied to pre-twisted blade. Pre-twist is applied with the help of HYPERMESH software.
