An energy-absorbing connection arrangement with a multitude of connectors for joining two components, such as a transverse member and a circular frame element, of an aircraft fuselage. Each connector comprises a headed shaft and the shafts reach through component boreholes. On the shaft ends facing away from the heads, counter-bearings are provided. At least one of the components comprises a fiber-reinforced plastic material. A head and/or counter-bearing of at least one connector rests against at least one underlay device. The underlay device is received in a guide groove in the first component, with the guide groove commencing in the region of the boreholes. The underlay device, upon exceeding a mechanical threshold load, is slidable away from the boreholes. Energy absorption takes place along a longitudinal center axis of the guide groove as a result of hole-bearing-stress failure and/or the shearing of the fiber-reinforced plastic material component.

Connection arrangement and structure

An aircraft fuselage including an outer skin that is stiffened by way of a backing structure and that delimits at least one passenger cabin and one cargo hold. In the vertical direction of the fuselage, the cargo hold is arranged below the passenger cabin. The backing structure in the cargo hold above a cargo-hold floor framework comprises at least two lateral quasi-joints, and below the cargo-hold floor framework comprises at least one further quasi-joint. In the cargo hold, in the longitudinal direction of the fuselage, a multitude of energy absorption devices, arranged one behind the other and acting in the transverse direction of the fuselage, are arranged for absorbing tensile loads.
