FIELD: aircraft engineering.
SUBSTANCE: stringer panel forming the skin and stringers from alternating monolayers of composite arranged in lengthwise direction along said stringers. Stringer cross-section features wavy shape. Stringer is divided into first part starting in skin depth and formed by extra lengthwise monolayers, second part with shin transverse monolayers are laid in separate strips, and third part formed by lengthwise and crosswise stringer monolayers above the last top layer of the skin. Crosswise monolayers extend to wave edges to overlap underlying crosswise monolayers Layers at stringer cross-section mid part can be made horizontal so that wave top has smooth horizontal section.
EFFECT: reliable joint between stringer and skin.
