This utility model relates to the field of
aviation connection structure technology, specifically to a docking
flange; it includes a main connecting ring, an auxiliary connecting ring, a reinforcing rib, and a positioning mechanism. The positioning mechanism includes a positioning pin, a positioning block, a limit seat, and a tensioning bolt. This utility model provides a load-bearing docking
flange structure for adding an optoelectronic
turret to the front of the airtight end frame of an aircraft
nose. Through the structure of the main connecting ring, auxiliary connecting ring, reinforcing rib, and positioning mechanism, the main connecting ring docks with the docking ring of the equipment, and the reinforcing rib provides support. At the same time, it transfers the load of the main connecting ring to the auxiliary connecting ring of the docking
flange. The auxiliary connecting ring transfers the load from the main connecting ring to the
airframe structure, while satisfying the connection between the docking flange and the front airtight end frame of the aircraft
nose. This enables the convenient installation of long-
cantilever, heavy-duty, ring-shaped interface equipment on the aircraft
nose.
