"Flapwise Bending Edgewise Bending(Peter J. Schubel, 2012)The data for the flap wise bending and edgewise bending can be measured andestablished statistically through Modal Analysis. This analysis helps in proofingthe data that how much load a blade can bear. This helps in identifying naturalfrequency, damping characteristics frequency and mode shapes of the windturbine blades. (Gunner C. Larsen, 2002) This analysis is purely experimental,hence is out of scope of this research.4. Fatigue LoadsThese loads occur when a material is subjected to a repeated non-continuousforce that causes the material to cross its fatigue limit. Operating wind turbineswithin the fatigue limits leads to inefficient blade designs & thus an optimizedblade design is always subjected to fatigue loads.Geographical Analysis:There have been a few studies across the world measuring wind turbineperformance and the effect of environmental factors on the same and hencelittle literature is available that describe the blade design parameters as pergeographical locations. (Vicky K Rathod, 2004)Through the little literature available, we were able to review some keyparameters that affect the blade design as per geographical locations. These are:- Wind Speed: the average wind velocity varies on a very large scale. Windturbines perform poorly at very low speeds and at very high speeds, bladescan be damaged hence the rotor need to be stopped.Even temperature plays a critical role in the variation of wind speed. (Kompulsa - Science And Technology)- Location: the wind varies at different locations such as - densely populatedregions, forests, buildings, hilly areas, plateau and plains, offshore regionsetc. Thus site location becomes a major factor.Sometimes, by observing the nearby trees also give an idea of the windspeed. Experts may observe the lean of the tree branches and have a generalidea of the wind speed. Local airports and Weather stations can also providethe same information. (Vicky K Rathod, 2004)- Height: it plays a very major role in the performance output of a windturbine. The wind generator should be mounted at a minimum height of 30feet in the absence of any obstruction within 300 feet of range.During our research, we came across a simulation website where one cantest output efficiency and cost per unit power generated by selectingdifferent parameters such as:? Geographical Location – offshore, plains or hills? Blade length, Blade Pitch? Tip shape, Airfoil shape? Turbine height? Some other parameters Simulation example from scienceofeverydaylife.comOptimization of Wind Turbine:Blade design optimization is very essential to achieve an optimized wind turbineoutput. The blade design optimization is achieved by blade design analysis. This isbased on BEM analyzing parameters such as airfoil shape, rotor speed, designattack angle, rated wind speed etc.As Burton et al. (2011) stated, “a successful blade design must satisfy a wide rangeof objectives too, some of which can be in conflict”. These objectives are:1. Maximize annual energy production2. Restrict the maximum power output in the turbine3. Endure fatigue loads4. Limit tip deflections to avoid blade and tower collisions5. Prevent resonances6. Minimize weight and cost. "
