In the scope of the ALaSCA project, a carbon fiber composite grid-type structure, called anisogrid structure, is investigated for the use in aircraft fuselages. The novel structural design presents two striking differences when compared to the traditional aircraft fuselage design: 1) the stiffening elements form a grid with non-rectangular skin bays, 2) grid stiffening elements are located on the inside as well as on the outside of the skin creating an antimetric structure. The unusual arrangement of stiffeners on either side of the skin leads to a difference in load carried by the inner and the outer stiffeners, which in turn could lead to an adverse structural response. The goal of the study presented in this report is to determine whether antimetry causes flight safety critical structural responses in the developed design.
