Estimating the term…
Proposed is an attachment arrangement (1) for attaching a component to the fuselage (3) of an aircraft, and an aircraft comprising such an attachment arrangement. The attachment arrangement (1) comprises an elongated stringer (5) that can be connected to the aircraft fuselage, and a fitting (11) that can be connected to the component. The stringer comprises a multitude of recesses (9) that are formed one behind the other in the direction of longitudinal extension of the stringer. The fitting comprises at least one engagement element (13) that is adapted for positive-locking engagement in the recesses (9) of the stringer (5). The stringer and/or the fitting can comprise CFC. The fittings can also comprise various other plastics or metal. Weight savings are achieved while at the same time providing stable and variably-positionable attachment. Furthermore, a method for constructing a stringer for an attachment arrangement is proposed, in which method, by providing reinforcement fibres adjacent to the recesses, a carbon scrim is locally reinforced around the recesses.
An attachment arrangement (1) for attaching a component to the fuselage (3) of an aircraft, wherein the attachment arrangement comprises:
The attachment arrangement of any one of the preceding claims, wherein the recesses are round.
The attachment arrangement of any one of the preceding claims, wherein the recesses have a cross-sectional area of at least 1 cm2.
The attachment arrangement of any one of the preceding claims, wherein the stringer is designed as a T-stringer, and wherein the recesses are arranged in the web of the T-stringer.
The attachment arrangement of any one of the preceding claims, wherein the stringer and/or the fitting are/is designed as an injection moulded part.
The attachment arrangement of any one of the preceding claims, wherein the stringer and/or the fitting comprise/comprises glass-fibre-reinforced plastic.
The attachment arrangement of any one of the preceding claims, wherein the stringer and/or the fitting comprise carbon-fibre-reinforced plastic.
The attachment arrangement of any one of the preceding claims, wherein the stringer and/or the fitting are/is a milled part or a carbon-fibre-reinforced Duroplast moulded part.
An aircraft comprising an attachment arrangement of any one of the preceding claims.
