THREE-LAYERED RIBBED PANEL Russian patent published in 2019 - IPC B64C3/26 B64C3/18 B32B3/12 

FIELD: aviation.

SUBSTANCE: invention relates to ribbed panel of swept wing. Technical result is achieved in a swept wing ribbed panel, which comprises a skin supporting the stringers and parallel to the flow of the rib. Skin, ribs and cross ribs are made integral. Transverse stiffening ribs are parallel to flow and intersect with longitudinal stiffeners at angles defined by sweep. At that, the ribs of the crosses play the role of deconcentrators due to thickening of the crosspiece by a value sufficient for placement of a fastener in it, installation and fixation of the second skin of the panel, which is attached to the free ends of the ribs of the crosses with the help of scrapers.

EFFECT: technical result is improved aerodynamic surface of panel.
