Description
Technical field
The utility model belongs to aviation wing structure design field, and in particular to a kind of discontinuous wing fixes leading edge.
Background technology
It is the fixed part in wing structure before front-axle beam that wing, which fixes leading edge, is primarily subjected to aerodynamic loading and becomes with wing
The stress that shape produces, when design, mainly consider rigidity Design.Wing fixes leading edge and 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, particularly with metal by docking partition plate
Rivet leading edge, it may appear that local stress is high, it is necessary to which skin thickness is thickeied or increases stringer quantity, so as to cause construction weight
Increase.
Utility model content
The purpose of this utility model is to provide a kind of discontinuous wing to fix leading edge, overcomes or alleviated by the prior art extremely
A few drawbacks described above.
The purpose of this utility model is achieved through the following technical solutions：A kind of discontinuous wing fixes leading edge, the fixation
Leading edge includes skins front edges, T-shaped partition plate, stringer, partition plate, double O shapes rubber profiles, front wall, and skins front edges bending is C-shaped,
T-shaped partition plate is arranged at the skins front edges both ends, and the front wall being connected with both ends T-shaped partition plate and length are provided with the skins front edges concave side
Purlin, and the multiple partition plates to connect with front wall, stringer of arranged for interval in the skins front edges concave side；Connect at T-shaped partition plate edge strip
It is connected to double O shape rubber profiles, each O-shaped rubber ring in this pair of O shape rubber profile respectively fixes the skins front edges in leading edge with one
Overlap joint.
Preferably, double O shapes rubber profiles are connected by pressing plate with the T-shaped partition plate edge strip, which is arranged at
Between two O-shaped rubber rings in double O shapes rubber profiles.
Preferably, the longitudinal profile being connected with both ends T-shaped partition plate is additionally provided with the skins front edges concave side, this is vertical
It is connected to section bar by cornual plate and each partition plate tail end.
The beneficial effect that a kind of discontinuous wing provided by the utility model fixes leading edge is, applied to metal riveting
Leading edge, leading edge section length is short, and without mechanically connecting between every section, every section of leading edge structure independent stressed, connects with wing-box
Spreading degree is short, and the area of stress influence produced with wing deformation is small, and large area reduces skin thickness or stringer quantity, so as to mitigate
Construction weight, while influence of the fixed leading edge to box section rigidity can be reduced.

Example property, it is intended to for explaining the utility model, and it is not intended that limitation to the utility model.Based on the utility model
In embodiment, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The discontinuous wing fixation leading edge to the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of discontinuous wing fixes leading edge, using metal riveting structure, fixed leading edge is covered including leading edge
The parts such as skin 1, T-shaped partition plate 2, stringer 3, partition plate 4, double O shapes rubber profiles 5, front wall 8.The bending of skins front edges 1 is C-shaped, at this
1 both ends of skins front edges arrangement T-shaped partition plate 2, which is used to separate two adjacent fixed leading edges.1 concave side of skins front edges
On be provided with the front wall 8 being connected with both ends T-shaped partition plate 2 and stringer 3, and arranged for interval is more in 1 concave side of skins front edges
A partition plate 4 to connect with front wall 8, stringer 3.For ensure partition plate 4 can be integrally detachable, partition plate 4 not with wing-box front-axle beam and wall
Plate (not shown) connects, but in order to increase the stability of every section of fixed leading edge itself, selects in 1 concave side of skins front edges
The longitudinal profile 7 being connected with both ends T-shaped partition plate 2 is also set up, which is connected by cornual plate and each 4 tail end of partition plate, i.e.,
Multiple 4 tail ends of partition plate are penetrated through using a longitudinal profile 7.T-shaped partition plate 2 at fixed leading edge segmentation, leading edge is fixed as both sides
The skeleton of segmentation, is connected with box section front wall and siding (not shown), and the T-shaped partition plate 2 is non-dismountable.As shown in Fig. 2, T-shaped
Double O shapes rubber profiles 5 are connected with 2 edge strip of partition plate, in order to ensure that rubber profile firmly installs, double O shapes rubber profiles 5 pass through pressure
