FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to airframe design, and can also be used in shipbuilding, machine building and other industries to obtain permanent joints during production and repair of structural elements in places, which do not allow double-sided approach to repaired section. Rivet consists of rod with head and axial cavity, core, made in form of rod with shank, diameter of which is equal to diameter of axial cavity of rivet, on one end of core is formed head, linear dimensions of which is greater than diameter of axial cavity, at distance equal to thickness of riveted pack from head of core on core has tear-off zone, and at other end of shank. Under the rod head of the rivet on external surface of the rod there is a slot with depth of 0.1–0.15 of the rivet diameter and length equal to the thickness of the riveted package, and the groove is filled with composition, the melting point of which is lower than the recrystallization temperature of the rivet material.
EFFECT: technical result of invention consists in improvement of reliability of permanent rivet connection, ensuring its tightness, due to soldering of rod with rifling package.
