Based on geometry which calculated in the CAD software a 3D model of the blade will be created. This further improve the accuracy of the data collected. The design team utilize those data to create the blade model.
Details parameters of aerodynamics profiles can be downloaded from Aerofoil Investigation database. Forces generated in an aerodynamic profile with various symbol which used for calculation Shape and forces generated are determined by the aerodynamic profiles and which can be found on Aerospace Institutes. 1 software with a set of wind speed and required span of the rotor. The design team later perform an analysis on the designed aerofoil profiles with a WIATRAK 1. Based on the information above mentioned, the calculation was done which involve calculation for the force that generated in the aerodynamic profile and lifting 4 forces produced by the aerodynamic blade profile. The selection is based on constraint from the environment, budget, requirements from the regulation and performance. The first step of the design process for a turbine blade involves choosing the aerofoil profiles for the blade. Due to such heavy computation involved, this approach becomes practically very challenging even with the advanced computational power”. 25 x 105 possible designs even with geometry assumed to be the same.
That is to say, for a turbine blade made of modestly three constituent materials with volume fraction 2% as the resolution, there are 1. For an example quote from reference documents, “For a 3D object with m types of materials and n number of variations for each material, the modelling space is E3 x nm dimensional. The creation process required high accuracy and reliability works performed as it involves a large number of variants and calculation for the surface profile, working parameter for the specific working environment and material for the turbine blade. CAD (Computer-Aid Design) program are able to produce 2D and 3D sketches which used in the manufacturing process and simulation.

The reason of choosing win turbine blade as a case study example is because of its complexity on not only shape but also involve heavy simulation on a designed model for performance and calculation on how to manufacture and bring the designed product to live. The design team mentioned in the following report are a team of personnel from the reference report. This leads us to the following case study report which will show an example of the process of design, simulate and modelling a wind turbine blade by a design team with the application of Computer-Aid Design software, engineering knowledge and simulation software. Computer-Aid Design software is one of those tools. With the help of all these tools, engineers or students nowadays are able to solve problems more effectively, productively and more innovative. Wondering if students or engineers living in the 21st century consider themselves fortunes as a lot of problems which previously solved by scholars, engineers, programmers from the past, simplified the solutions and consolidate into various tools to make solving some of the problems easier than ever.
