The invention relates to a connecting structure of an all-composite winged ship, each component of the Wing-in-Ground effect ship is provided with the same connecting part, A PVC structural foam corematerial, A FRP
surface plate is arrange on that upper and lower surface of the foam core material of the PVC structure, one end of the FRP
surface plate is connected with the FRP connection plate, AFRP connection layer plate is provide with a notch in that middle of the joint with the FRP
surface plate, A PVC structural foam core material extend into that notch, the FRP connection layer plate isformed into a
solid plate structure at one end away from the FRP surface plate, the
solid plate structure of the two members to be connected overlaps upwardly and downwardly, A plurality of double-row staggered through holes are arranged at the overlapping position, a
metal sleeve liner is bonded with
epoxy resin in the through holes, and bolts are installed in the
metal sleeve liner. The invention adopts the boss structure respectively, and the split wing box connects the
hull with the aft wing and the ground effect wing, the connection is firm, and the manufacturing, disassembly and
assembly are convenient, and the
utilization rate of the
hull space is improved.
