Abstract
The utility model belongs to the technical field of airplane structure design, and relates to a large-opening combined wing rib; comprises a rib body (1) and a large opening cover (2); the utility model transfers the assembly path and the maintenance path from the wall plate to the secondary load-bearing structure of the wing rib by using the large-opening combined wing rib, thereby avoiding the opening of a hole on the part with larger load, such as the wall plate, and the wing rib form has great weight reduction effect on the wing; the access opening of the rib can be designed to be larger, and is more convenient for personnel to enter and exit compared with the opening on the wall plate. For the sealing rib, a small access cover is designed on the large cover, so that the workload of maintenance is reduced.
Description
Technical Field
The utility model belongs to the technical field of aircraft structural design, a big opening combination wing rib is related to.
Background
The wing rib of the airplane is used as a secondary bearing component, the influence of the maintenance access opening on the wing rib on the main bearing line is small, but the wing rib structure efficiency is reduced sharply due to the fact that the wing rib is too large in opening, and the surrounding structure cannot be effectively supported. Meanwhile, the opening of the rib is small and cannot be used as an assembly passage or an overhaul passage for personnel to enter and exit, and if the opening is too large, the structural efficiency of the rib is reduced sharply, and weight is increased.
Disclosure of Invention
The utility model aims at: the invention designs a brand-new combined wing rib, can realize all functions of the wing rib, provides an open assembly passage and an overhaul passage, and designs a special overhaul cover cap to facilitate daily overhaul.
The technical scheme of the utility model: a large-opening combined wing rib is characterized by comprising a rib body 1 and a large opening cover 2; an opening matched with the large opening cover 2 is formed in the rib body 1, and the large opening cover 2 is connected with the rib body 1 through a bolt and a supporting plate nut.
The large opening cover 2 is provided with a plurality of lightening holes with openings.
A small access hole is formed in the large opening cover 2, and the access hole cover 4 is used for plugging.
Maintenance flap 4 lower cushion sealing rubber ring 3
The service flap 4 is arranged in the middle of the large flap 2.
The reinforcing ribs on the rib body 1 and the large opening cover 2 are in one-to-one correspondence.
The utility model has the advantages that: by using the large-opening combined wing rib, an assembly passage and an overhaul passage are transferred from the wall plate to a secondary bearing structure of the wing rib, so that holes are prevented from being formed in a part with larger load, such as the wall plate, and the wing rib has a great weight reduction effect on the wing.
The access opening of the rib can be designed to be larger, and is more convenient for personnel to enter and exit compared with the opening on the wall plate.
For the sealing rib, a small access cover is designed on the large cover, so that the workload of maintenance is reduced.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
when the upper edge strip of the wing panel stringer is double-flanged, a corner piece is required to connect the stringer and the wing rib to provide a support for the stringer and increase the stability of the stringer. Use the utility model discloses a connected mode is connected stringer top edge and rib.
The same connection angle piece can be used for both stringer axis and rib web angle changes, or stringer parameter changes.
As shown in fig. 1 and 2, the combined wing rib mainly comprises a rib body (1) and a large opening cover (2), wherein the rib body is provided with a large opening for personnel to pass through, and the rib body is used as an assembly passage in the assembly process and can be used as an overhaul passage in the later period of airplane overhaul; the large opening cover is connected with the rib body through the bolts and the supporting plate nuts, the load on the rib body can be transmitted to the large opening cover through the circle of bolts, the rib body and the support columns of the large opening cover are arranged correspondingly as much as possible, and the support columns are favorably pressed.
Example 1: if the rib has no sealing requirement, lightening holes are opened on the large cover (2) as shown in figure 2, and daily maintenance can be carried out through the lightening holes.
Example 2: if this rib has sealed requirement, rib structural style can also open a little access hole on big flap (2) as shown in figure 1 and figure 3, carries out the shutoff with access hole lid (4), and fills up sealed rubber circle (3) under the access hole lid, only needs the little flap of dismouting during daily maintenance, reduces the quantity of dismouting bolt.
Claims (5)
1. The large-opening combined wing rib is characterized by comprising a rib body (1) and a large opening cover (2); an opening matched with the large opening cover (2) is formed in the rib body (1), and the large opening cover (2) is connected with the rib body (1) through a bolt and a supporting plate nut; a small access hole is formed in the large opening cover (2) and is blocked by the access hole cover (4).
2. The large-opening composite rib as claimed in claim 1, wherein the large flap (2) is provided with a plurality of open lightening holes.
3. The large-opening composite rib as claimed in claim 1, wherein the access cover (4) is underlaid by a sealing rubber ring (3).
4. The large-opening composite rib as claimed in claim 1, wherein the access door (4) is at a middle position of the large door (2).
5. The large-opening combined wing rib as claimed in claim 1, wherein the reinforcing ribs on the rib body (1) and the large-opening cover (2) are in one-to-one correspondence.
