Abstract
The present invention provides the connection structure between a kind of fixed leading edge segmentation, two partitions (3) are set at two fixed leading edge segmentations, partition (3) is the L-shaped angle section in section, two partitions (3) are oppositely arranged in the fixed leading edge in two sides, wherein the edge strip part in two partitions (3) is away from each other placement, there are gaps between the fixed leading edge in two sides, rubber tube (2) are set in gap, rubber tube (2) is made of O-shaped rubber ring and two rubber strips collinearly arranged being symmetricly set in O-shaped rubber ring, O-shaped rubber ring is inlaid between the fixed up-front gap in two sides, two rubber strips are plugged between the skins front edges in fixed leading edge (1) and partition (3), partition (3), rubber strip and skins front edges (1) three are detachably connected.Connection structure provided by the present invention makes every section of fixed leading edge structure independent stressed with the relative motion between deformation-compensated every section fixed leading edge of rubber tube, reduces local stress, mitigates construction weight.
Description
Technical field
The invention belongs to aviation wing structure design fields, and in particular to the connection structure between a kind of fixed leading edge segmentation.
Background technique
The fixed leading edge of wing is the fixed part in wing structure before front-axle beam, is primarily subjected to aerodynamic loading and becomes with wing
The stress that shape generates, when design, mainly consider rigidity Design.The fixed leading edge of wing considers the factors such as material, technique, is designed to
Segmental structure, the fixed leading edge segmentation of tradition are connected as an entirety, leading edge entirety stress by docking partition, it may appear that answer part
Power is high, construction weight weight.
Summary of the invention
The purpose of the present invention is to provide the connection structures between a kind of fixed leading edge segmentation, overcome or alleviated by the prior art
At least one drawbacks described above.
The purpose of the present invention is achieved through the following technical solutions: the connection structure between a kind of fixed leading edge segmentation, described in two
Two partitions are set at fixed leading edge segmentation, and two partition respectively as the fixed up-front skeleton in two sides, fix between leading edge by two sides
There are gaps, and rubber tube is arranged in the gap, which is covered by the leading edge in the fixed leading edge of detachable fastener and two sides
Skin and partition are connected.
Preferably, the partition is the L-shaped angle section in section, and two partitions are oppositely arranged on the fixed leading edge in the two sides
On, wherein the edge strip part in two partitions is away from each other placement.
Preferably, the rubber tube is by O-shaped rubber ring and what is be symmetricly set in O-shaped rubber ring two collinearly arrange
Rubber strip is constituted, and O-shaped rubber ring is inlaid between the fixed up-front gap in the two sides, and two rubber strips are plugged in fixed leading edge
In skins front edges and partition between, partition, rubber strip and skins front edges three by detachable standard component be connected.
The beneficial effect of connection structure between a kind of fixed leading edge segmentation provided by the present invention is that fixed leading edge is segmented
Between there are certain interval, centre is connected using rubber tube, with opposite between deformation-compensated every section fixed leading edge of rubber tube
Movement, thus make every section of fixed leading edge structure independent stressed, the stress that with wing deformation generates short with wing-box connection length
The zone of influence reduces, to mitigate construction weight；Gap between every section of fixed leading edge is compensated using rubber tube, while can be played
Sealing function.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the connection structure between the fixed leading edge segmentation of the present invention.
Appended drawing reference:
1- skins front edges, 2- rubber tube, 3- partition.
Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
The connection structure fixation leading edge segmentation of the invention is described in further details with reference to the accompanying drawing.
As shown in Figure 1, the connection structure between a kind of fixed leading edge segmentation, two fix two partitions 3 of setting at leading edge segmentations,
Two partitions 3 are oppositely arranged in the fixed leading edge in two sides, fix respectively as two sides by the angle section that the partition 3 selects section L-shaped
Up-front skeleton, wherein the edge strip part in two partitions 3 is away from each other placement.There are certain interval between the fixed leading edge in two sides,
Rubber tube 2 is set in gap, which selects by O-shaped rubber ring and two conllinear arrangements being symmetricly set in O-shaped rubber ring
The pattern that constitutes of rubber strip, O-shaped rubber ring part is inlaid between the fixed up-front gap in two sides, and two rubber strips are plugged in
Between skins front edges 1 and partition 3 in fixed leading edge, partition 3, rubber strip and 1 three of skins front edges pass through detachable fastening
Part is connected (common detachable standard component can be selected in the detachable fastener), so that rubber tube 2 is connected with the fixed leading edge in two sides.That is rubber
The rubber strip of sebific duct 2 is connected on the edge strip of two partitions 3, and skins front edges 1 cover on the outside of 2 rubber strip of rubber tube, with can
Standard component connection is unloaded, the intermediate O-shaped rubber ring portion extrusion of rubber tube 2 is between two partitions 3.It is deformation-compensated with rubber tube 2
Relative motion between every section of fixed leading edge makes every section of fixed leading edge structure independent stressed, reduces local stress, mitigates structure weight
Amount, while playing sealing function.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of protection of the claims
It is quasi-.
