If this is pure design work in an office, this may require special skills or experience. For example: blade design in wind power generation; design of cam curves for automotive engines and transmissions; There are other, more distant individual positions that are not universal. Good luck
The blade diameter is not professional, it should be the sweeping diameter. Common blade shapes are 126/110/114, etc., and the corresponding blade sizes are 68m, 54m and 56m; now the diameter of the largest wind turbine blade has exceeded 70 meters, which is equivalent to the wingspan of a Boeing; aircraft.
When it comes to materials, it's more complicated. Different parts of the blade have different materials. Generally speaking, three categories are used, carbon fiber and fiberglass as the outer surface, and balsa wood and mouss as surface. base material.
The other thing is that carbon fiber binder is ideal because it has better strength and is lighter, but it is also a problem because it is too expensive. Balsa wood is balsa wood. As for foam, there are relatively many types, but generally hard foam products account for 90% of the share in this field.
The main materials of wind turbine blades are fiberglass fabrics and reinforced resins.
Large megawatt blade spar caps can use a carbon-glass hybrid design, and hull cores typically use glass. . Fiber fabric
In addition to LM, domestic and foreign large wind turbine blade manufacturers such as VESTAS, SIEMENS, GAMESA, etc. all use epoxy resin systems; resin and fiberglass fabric, using polyester resin, the bonding speed is fast, the prThe post-curing process does not require heating, and the mold rotation efficiency is high;
