“…The desire to create a structure combining the advantages of a sandwich structure in combination with high reliability makes sense. 18 It is possible to ensure increased safety in case of damage through the use of a sandwich structure core with high rigidity characteristics. In such a situation, if a crack has formed on one of the skins, the core would take over the resistance to operational loads and ensure aircraft structure functioning until the end of the flight.…”

The possibility of using a new type of core structure for the aircraft lift surface, which is an alternative to the conventional structural layout, was reviewed. The study was carried out using the rudder of the ultralight aircraft "MC-15 Cri-Cri" as the example. A comprehensive comparative analysis of the prototype design with the proposed alternative option was made. The analysis of the studied structural layout variants strength characteristics was carried out using FEM calculations due to the complexity of the geometric shape of the proposed alternative. The prospects of using a prefabricated faceted core structure instead of the classical structural layout of the aircraft lift surface were revealed.
