5 Design presentation This chapter introduces the wind turbine design proposal, which has been developed on basis of the principal concept, described in section 4.5. A 3D illustration of the overall wind turbine design is shown on figure 5.1. Figure 5.1: 3D illustration of overall wind turbine design 35
DESIGN PRESENTATION The main dimensions of the wind turbine are illustrated on figure 5.2. 36 Figure 5.2: Overall wind turbine design and main dimensions Figure 5.3 contains a more detailed overview of the wind turbine and identifies its key components. A full overview of the wind turbine components can be found in the compo- nent diagram of att. 12. Reference is also made to the product drawing of att. 11, which contains further technical details, including main dimensions, wind turbine data and detail views.
