Embodiment Construction

[0017] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0018] Such as Figure 1 to Figure 2 As shown, the connection assembly between the rib and the long stringer of the present invention includes: a rib web 2 , a long stringer flange 3 and a connecting angle piece 1 .

[0019] Specifically, both the rib web 2 and the long stringer flange 3 are provided with through holes.

[0020] The connecting angle piece 1 includes two mutually connected plate surfaces, there is an angle between the two plate surfaces, and through holes are respectively opened on each plate surface, and then the bolts 4 are passed through one of the connecting angle piece 1 respectively. The through holes on the plate surface and the through holes o...

Abstract

The invention provides a wing rib and stringer connecting module, and relates to the field of aircraft structure design. The wing rib and stringer connecting module comprises a wing rib web plate (2),a stringer edge bar (3) and a connecting angle piece (1). Two plate surfaces of the connecting angle piece (1) are connected with the wing rib web plate (2) and the stringer edge bar (3) through bolts (4); an included angle between two plate surfaces of the connecting angle piece (1) can be set as any angle; when the angles of the wing rib web plate and a stringer are changed, or the width of thestringer edge bar is changed, the connecting angle piece (1) is also applicable, and during applying, the connecting angle piece (1) can be produced as an all-same piece; the connecting angle piece (1) is small in size, so that the weight can be reduced by 40-60%; and meanwhile, the connecting angle piece (1) directly supports the upper part of the stringer, so that the force transfer efficiencyis improved. The wing rib and stringer connecting module is simple, convenient and excellent in connecting effect.

Description

technical field [0001] The invention relates to the field of aircraft structure design, in particular to a connection assembly between wing ribs and long trusses. Background technique [0002] The ribs and girders are generally connected by connecting angle pieces, and each rib and each stringer needs a angle piece, and there are a large number of angle pieces, making the manufacture and assembly very cumbersome and error-prone. For a wider girder top edge, the cantilever of the gusset becomes longer, the force transmission efficiency becomes lower, and the weight increases, and the gusset cannot be made into the same piece because of the change of the cantilever length. How to make the corner pieces identical, improve the force transmission efficiency of the corner pieces, and reduce the weight of the corner pieces is a difficult problem. Contents of the invention [0003] The present invention provides a connection assembly between a wing rib and a long stringer to solv...
