Computerized Method for Preliminary Structural Design of Composite Wind Turbine Blades

摘要: A computerized method has been developed to aid preliminary design of composite wind turbine blades. The allows for arbitrary specification the chord, twist, and airfoil geometry along blade an number shear webs. Given external description its load distribution, Fortran code uses ultimate-strength buckling-resistance criteria compute thickness load-bearing laminates. also includes analysis option obtain properties if a laminates schedule is prescribed. These include bending stiffness, torsion mass, moments inertia, elastic-axis offset, center-of-mass offset blade. Nonstructural materials-gelcoat, nexus, bonding adhesive-are included computation mass. This paper describes assumed structural layout within blade, approach, computational process. Finally, example illustrates application hypothetical properties.
