“…The blades are generally characterised by the airfoil used, the chord length and the span of the blade. Many simulations have been done on the effect of chord length on the stress distribution [3] but the effect of twist is yet to be analyzed. The twist of the blade is very important to determine the mass flow rate over the blades.…”

The past decade has experienced a boom in industries and engineering. This has led to an increase in demand for power. The major power generators are wind farms, thermal power plants and hydroelectric power plants. All these industries employ a common method of harnessing power-Turbines. The efficiency of these turbines can be improved by reducing the material used or by increasing the longevity of the blades by either changing the chord length or the twist angle of the turbine blades. Based on the applications of the turbine, these blades have different geometries i.e. different airfoils, different chord lengths and different degrees of twists. The current paper attempts to analyze the effect of chord length and angle of twist on the von-mises stress distribution over the wing of a thin airfoil, namely NACA 5504 using finite element methods. The blade is assumed to be made of aluminum material.
