Figure 3.25: The two most signicant modes of the battery support 69
3.10 Summary Through this chapter, the design of a new support for the batteries was discussed. First, the problems encountered with the last year's design were exposed to explain why this particular design had to be given up. Then, the available mass budget to realize this support was calculated, which is a crucial step when a new design had to be created. The selection of the several components which have to be included inside the support, was also exposed. In addition, the material selection, which has to be in accordance with several requirements that were listed, was studied. Finally, the design procedure was presented step by step, just like it progressed during the whole year. This design was then validated by several analysis and calculations. At the moment where this thesis ends, the plans are provided to the support's manufacturers (a rst rough shape of the box is presented in Figure 3.26).
