The utility model discloses aircraft tail cone point designs alone, and tail cone point and the integrative design time in tail cone middle section among the prior art have been overcome in installation and tail cone middle section and since the covering influence with the side joining of plates aircraft pneumatics and stealth can the defect.
Description
Technical field
This utility model relates to field of airplane structure, is specifically related to a kind of airplane tail cone.
Background technology
Tail cone point is positioned at airplane tail terebrantia, it it is structure necessary in aircraft, in prior art, the tail cone point structure of aircraft uses the hypervelocity molding of upper and lower eyelid covering or diffusion to connect manufacturing technology, is mechanically connected with tail cone sidewall by stringer, will be after stringer be connected with tail cone sidewall, directly forming tail cone, and do not have single tail cone point or the differentiation in tail cone stage casing, this structure can cause existing between the upper and lower eyelid covering of tail cone and sidewall gap, surface quality is poor, affects pneumatic, the Stealth Fighter of aircraft.
Utility model content
The purpose of this utility model is to provide a kind of airplane tail cone, installs and tail cone stage casing, when overcoming that in prior art, tail cone point is with tail cone stage casing Integral design, affects due to eyelid covering and the connection of side plate that aircraft is pneumatic and the defect of Stealth Fighter.
Described tail cone point includes tail cone point body and lap segment, described tail cone point body includes wainscot and lower wall panels, wainscot and lower wall panels while intersecting, corresponding another side opens, form cavity, wainscot is connected with each other by sidewall paneling with the side of lower wall panels, wainscot, lower wall panels and sidewall paneling are collectively forming conical hollow structure, the opening part of described conical hollow structure is provided with step, form described lap segment, described lap segment embeds the open-mouth in described aircraft tail cone stage casing, and is fastenedly connected, and described tail cone point body is printed by 3D and manufactures.
Preferably, the girth of described lap segment is less than the girth of the opening part of described conical hollow structure.
In such scheme preferably, lap segment is riveted on the open-mouth in aircraft tail cone stage casing.
In such scheme preferably, tail cone point body welds with lap segment.
In such scheme preferably, tail cone point body is one-body molded with lap segment.
The utility model has the advantage of:
By the stage casing of tail cone is separated design with tail cone point, when overcoming in prior art tail cone point with tail cone stage casing Integral design, affect due to eyelid covering and the connection of side plate that aircraft is pneumatic and the defect of Stealth Fighter.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of this utility model airplane tail cone.
Wherein: 1 is tail cone point body, and 2 is lap segment, and 11 is wainscot, and 12 is lower wall panels, and 13 is sidewall paneling.
Detailed description of the invention
Clearer for the purpose making this utility model implement, technical scheme and advantage, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is further described in more detail.In the accompanying drawings, the most same or similar label represents same or similar element or has the element of same or like function.Described embodiment is a part of embodiment of this utility model rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left ", " right ", " vertically ", " level ", " push up ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that restriction to this utility model protection domain.
nullThis utility model provides a kind of airplane tail cone，Install and tail cone stage casing，When overcoming tail cone point and tail cone stage casing Integral design in prior art，Affect due to the connection of eyelid covering and side plate that aircraft is pneumatic and the defect of Stealth Fighter，As shown in Figure 1，Described device includes tail cone point body 1 and lap segment 2，Described tail cone point body 1 includes wainscot 11 and lower wall panels 12，Wainscot 11 and lower wall panels 12 while intersecting，Corresponding another side opens，Form cavity，Wainscot 11 is connected with each other by sidewall paneling 13 with the side of lower wall panels 12，Wainscot 11、Lower wall panels 12 and sidewall paneling 13 are collectively forming conical hollow structure，The opening part of described conical hollow structure is provided with step，Form described lap segment 2，Described lap segment 2 embeds the open-mouth in described aircraft tail cone stage casing，And be fastenedly connected，Described tail cone point body 1 is printed by 3D and manufactures.
In the present embodiment, the girth of described lap segment 2 is less than the girth of the opening part of described conical hollow structure.With reference to Fig. 1, in order to ensure that airplane tail cone can preferably be connected with aircraft tail cone stage casing, so, lap segment 2 is set to the step to contract of the opening part of described conical hollow structure, i.e. aircraft tail cone stage casing want to accommodate described lap segment 2 with the limit shape frame that airplane tail cone contact position is formed.
In the present embodiment, lap segment 2 is riveted on the open-mouth in aircraft tail cone stage casing.
The present embodiment, tail cone point body 1 is one-body molded with lap segment 2, and in an alternative embodiment, tail cone point body 1 welds with lap segment 2.
The present embodiment by individually designed airplane tail cone, is installed and tail cone stage casing, when overcoming that in prior art, tail cone point is with tail cone stage casing Integral design, affects due to eyelid covering and the connection of side plate that aircraft is pneumatic and the defect of Stealth Fighter.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit.Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
