NODE OF THE FUSELAGE COMPARTMENT WITH MESH AND TRADITIONAL CONSTRUCTIVE-POWER CIRCUITS

摘要

FIELD: aviation.SUBSTANCE: invention relates to the field of aviation structures with various structural-power circuits (SPC), in particular, to the grid power structure of the fuselage compartment of a civil aircraft. Joint unit of the fuselage compartments with a mesh and traditional SPC contains spiral ribs and an end ring rib of the mesh compartment. Moreover, the spiral ribs are released beyond the edge annular rib for a distance of at least 10 mm in such a way that the intersecting ribs form an arc of a circle with a radius of at least 10 mm. Metal frame with grooves is placed close to the end ring rib, into which are placed spiral ribs outside the end rib, covered with a lid, which is tightened to the metal frame by bolts. Sheathing and stringers of the compartment with traditional SPC are connected to the metal frame through fittings by means of a bolted connection. Sheathing of adjacent compartments is attached with an overlap to the metal frame by means of a bolted connection. Moreover, the width of the end annular rib is not less than the width of the spiral ribs.EFFECT: necessary strength of the connection of the mesh compartment with the compartments of the traditional SPC fuselage is being achieved.1 cl, 3 dwg
