A connection structure of an all-composite ground-effect wing ship

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of wing-in-ground effect ships, in particular to a connection structure of a full-composite material wing-in-ground effect ship. Background technique [0002] Wing-in-ground-effect vehicles (Wing-in-ground-effect vehicles) are ships made using the principle of ground effect. When the wings move close to the surface, the influence of the surface on the airflow is used to generate surface effects, which increases the lift-to-drag ratio of the wings. Not only can the propulsion power be reduced, but also keep sailing away from the ground. Wing-in-ground boats fly at a low altitude of 1 to 6 meters above the water surface. Once an emergency occurs, they can land on the water surface at any time, with high safety. WIG craft using composite materials can significantly reduce its structural weight and improve flight performance, but due to the anisotropy and no plastic deformation of composite materials, composite...

Problems solved by technology

[0005] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a connection structure of a full-composite wing-in-ground ship, so as to solve the problem that the full-composite wing-in-ground ship cannot withstand concentrated loads caused by the characteristics of the composite material itself. The strength and stiffness of the components at the connection do not meet the safety and reliability requirements, as well as technical problems such as low space utilization and inconvenient disassembly and assembly caused by the connection structure
