Description
Technical field
The invention belongs to aviation wing structure design fields, and in particular to a kind of fixed leading edge of discontinuous wing.
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, particularly with metal by docking partition
Rivet leading edge, it may appear that local stress is high, needs to thicken skin thickness or increases stringer quantity, so as to cause construction weight
Increase.
Summary of the invention
The purpose of the present invention is to provide a kind of fixed leading edges of discontinuous wing, overcome or alleviated by least the one of the prior art
A drawbacks described above.
The purpose of the present invention is achieved through the following technical solutions: a kind of fixed leading edge of discontinuous wing, the fixed leading edge
Including skins front edges, T shape partition, stringer, partition, double O shape rubber profiles, front wall, skins front edges bending is C-shaped, before this
T shape partition is arranged at edge covering both ends, is provided with the front wall being connected with both ends T shape partition and stringer in the skins front edges concave side,
And the multiple partitions to connect with front wall, stringer of arranged for interval in the skins front edges concave side；It is connected at T shape partition edge strip
Double O shape rubber profiles, each O-shaped rubber ring in double O shape rubber profiles are respectively overlapped with the skins front edges in a fixed leading edge.
Preferably, double O shape rubber profiles are connected by pressing plate with the T shape partition edge strip, which is set to
Between two O-shaped rubber rings in double O shape rubber profiles.
Preferably, it is additionally provided with the longitudinal profile being connected with both ends front wall in the skins front edges concave side, the longitudinal direction
Profile is connected by cornual plate and each partition tail end.
The fixed up-front beneficial effect of a kind of discontinuous wing provided by the present invention is, before being applied to metal riveting
Edge, leading edge section length is short, and without mechanical connection between every section, every section of leading edge structure independent stressed is connect with wing-box
Length is short, and the area of stress influence generated with wing deformation is small, and large area reduces skin thickness or stringer quantity, to mitigate knot
Structure weight, while influence of the fixed leading edge to box section rigidity can be reduced.

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 fixed leading edge of discontinuous wing of the invention is described in further details with reference to the accompanying drawing.
As shown in Figure 1, a kind of fixed leading edge of discontinuous wing, using metal riveting structure, fixed leading edge includes that leading edge is covered
The parts such as skin 1, T shape partition 2, stringer 3, partition 4, double O shape rubber profiles 5, front wall 8.The bending of skins front edges 1 is C-shaped, at this
T shape partition 2 is arranged at 1 both ends of skins front edges, and the T shape partition 2 is for separating 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 shape partition 2 and stringer 3, and arranged for interval is more in 1 concave side of skins front edges
A partition 4 to connect with front wall 8, stringer 3.To guarantee that partition 4 can be whole detachable, partition 4 not with wing-box front-axle beam and wall
The connection of plate (not shown), but in order to increase the stability of every section of fixed leading edge itself, it selects in 1 concave side of skins front edges
The longitudinal profile 7 being connected with both ends front wall 2 is also set up, which is connected by cornual plate and each 4 tail end of partition, i.e., more
A 4 tail end of partition is penetrated through using a longitudinal profile 7.T shape partition 2 at fixed leading edge segmentation, as the fixed preceding fate in two sides
The skeleton of section, connect, the T shape partition 2 is non-dismountable with box section front wall and siding (not shown).As shown in Fig. 2, T shape every
Double O shape rubber profiles 5 are connected at 2 edge strip of plate, in order to guarantee that rubber profile firmly installs, double O shape rubber profiles 5 pass through pressing plate
6 are connected with 2 edge strip of T shape partition, which is set between double O shape 5 liang of O-shaped rubber rings of rubber profile, double O shape rubber-types
Each O-shaped rubber ring in material 5 is respectively overlapped with the skins front edges 1 in a fixed leading edge, i.e., two adjacent skins front edges 1 are covered in double O
5 outside of shape rubber profile, without mechanical connection between skins front edges 1 and T shape partition 2.
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
