Method for double-shear joining of panels in aerofoil-fuselage assembly of airplane, involves optimizing total transfer rate by increasing force transfer rate of low density fish-plate and decreasing transfer rate of high density fish-plate

摘要

The method involves joining two fish-plates (3, 4) that are provided with high density and low density, respectively. A total force transfer rate is optimized by increasing force transfer rate of the low density fish-plate and decreasing force transfer rate of the high density fish-plate such that overall mass of the fish-plates is minimized. A material of the low density fish-plate is selected such that the material exhibits higher rigidity than the high density, where the low and high density fish-plates are made of metal alloy and composite material, respectively. An independent claim is also included for an aerofoil-fuselage assembly.
