Original Kurzfassung:
Spoilers of large commercial aircrafts are currently realized in composite sandwich design. Nowadays, research is focused on monolithic highly integrated composite structures, which substitute such sandwich designs, mainly because of commercial aspects. From a structural point of view, this is difficult to justify. Sandwich designs are perfectly suitable for structures exposed to bending moments like aircraft spoilers. However, monolithic structures can be produced cheaper and integration of sub-components in one single part is easier. Two monolithic alternatives, which fulfill all structural requirements, are considered in terms of applied materials, manufacturing processes and the resulting manufacturing costs. Those are compared to a standard sandwich spoiler to provide a holistic view on the selection of designs, processes and materials for future aircraft spoilers
