FIELD: aviation.
SUBSTANCE: invention relates to aircraft construction and relates to aerodynamic surfaces of polymer composite materials of high-extension wings, wing devices and tail surfaces. Caisson of the detachable part of the wing of the large extension consists of a top panel with integrated spars connected to the bottom panel. Upper and lower panels are made of load-bearing layers of polymeric composite material and aggregate. In this case, the height of the filler of the upper panel exceeds the height of the filler of the bottom panel.
EFFECT: increase in the load-carrying capacity of the structure, an increase in specific characteristics, and an increase in manufacturability are achieved.
