The results of determining the criterion of the working capacity of a five-ply structure of a glass-reinforced plastic fairing of a DRLOA-50 aircraft are reported. As a result of the performed accelerated climatic tests, it is revealed that, for the glass-reinforced plastic honeycomb structure of the fairing wall, the most sensitive characteristic to aging processes and the action of service and climatic factors is the tensile strength of the adhesive joint prepared with VK-36RD film adhesive. The range of admissible values of this and other strength characteristics of the composite constituting the wall of a large-scale fairing are additionally revealed.
