Abstract

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.
