Integral rib. CFRP diaphragm with swelled cutouts. Wing leading edge

Integral CFRP rib with longitudinal and transverse stiffeners

for the perception of high loads caused by concentrated effects in aircraft primary structures: wings and high-lift devices, fin, stabilizer, control surfaces

Weight saving over metallic analogs of no less than 18%
No mechanical and adhesive-bonded joints
15% reduction in a manufacture cycle through the co-curing of structural components
No shims and shimming operations in the process of unit assembly

CFRP diaphragm with swelled cutouts

for stiffening airframe structure skins and nose units - wings, high-lift devices, fin, stabilizer, control surfaces

Weight saving over metallic analogs of no less than 12%
Higher load-carrying capacity of a web under 14% shear
No mechanical joints
10% reduction in a technological cycle through the formation of a cutout stiffened in the process of formation with a swelled edge

Wing leading edge -

an integral multiweb highly and mid-loaded structure from CFRP and organoplastics

Weight saving of no less than 20%
Higher structure fatigue life and vibration resistance
No mechanical and adhesive-bonded joints
10-15% reduction in a manufacture and assembly cycle through the co-curving of structure elements
Lack of shimming and assembly operations
