FIELD: manufacture of structural articles for aircraft members, fuselage and wings in particular.
SUBSTANCE: proposed method includes laying lower and upper skins from several layers of prepreg in molds, molding and mounting longitudinal and transversal stiffening members by means of trihedlar elastomer inserts provided with transversal grooves. Longitudinal members in form of solid-state rods are laid above trihedlar elastomer inserts. Lower skin is covered with reinforcing prepreg tapes at areas where longitudinal and transversal stiffening members are located. Transversal framework is made in form of truss ribs inserted into transversal grooves of trihedral elastomer inserts.
EFFECT: facilitated procedure; reduction of mass and time for manufacture.
