Below by further specifically describe to hang box section 100 wainscot 120 design details:
<The vertical height of top connection>
The wainscot 120 of the hanging box section 100 of the present invention is formed the construction of protrusion by multiple plate portions, and top connection 110 is then
It is positioned at the position that each plate portion mutually intersects, therefore relative to existing hanging box section 10 is in horizontal wainscot 11 substantially
For, top connection 110 of the invention is in elevated height and position, which is the vertical of top connection 110
Highly.
Fig. 7 schematically shows the top connection 110 in different vertical height and positions, wherein, represent existing with solid line
The wainscot 11 of technology, is represented by dotted lines plate portion 122 after the wainscot front panel portion 121 and wainscot of wainscot 120 of the invention,
Filled arrows then represent the load 200 being applied in top connection 110, which has along wainscot front panel portion
The 121 front panel portion sharing parts of the load 211 transmitted and the rear plate portion sharing part of the load 212 transmitted along plate portion after wainscot 122.From figure
It can be seen that the rise of the vertical height with top connection 110, the front panel portion sharing part of the load 211 and the rear plate portion sharing part of the load 212 are all
Correspondingly reduce.When hang box section 100 vertical height reach connector ideal height Hu when, the direction of top connection load 200 with
The extending direction of wainscot front panel portion 121 is parallel, and top connection load 200 is all transmitted in wainscot front panel portion 121 at this time, and
Component after wainscot in plate portion 122 is zero.In a kind of conventional hanging box section 100, connector ideal height Hu is substantially
1147mm。
But in actual structure, due to hanging the size limitation of box section 10, top connection 110 is unable to reach connector reason
Think height Hu, and can only achieve at the radome fairing upper level Hl of top radome fairing.In the hanging box section 100 of stock size
In, radome fairing upper level Hl is typically at around 216mm.
Fig. 8 shows relation between the ratio for reflecting different connector height and positions and siding load-top connection load
Curve map.It can see from the curve map shown in Fig. 8, with the rise of top connection 110,211 He of the front panel portion sharing part of the load
The plate portion sharing part of the load 212 all gradually reduces afterwards, and when reaching connector ideal height Hu, the front panel portion sharing part of the load 211, which is equal to, above to be connect
Head load 200, then the plate portion sharing part of the load 212 is zero.And the radome fairing upper level that can actually reach in top connection 110
At Hl, 1.89 times of the substantially top connection load 200 of the front panel portion sharing part of the load 211, then the plate portion sharing part of the load 212 substantially on
1.122 times of joint load 200.But, since the front panel portion sharing part of the load 211 and the rear plate portion sharing part of the load 212 are all in upper wall
Transmitted after plate front panel portion 121 and wainscot in the face of plate portion 122, caused is tension and compression deformation in face, therefore compared to existing
For hanging the vertical load on the wainscot 11 of box section 10, its caused internal stress is still much lower.
Further, consider that the height and position of top connection 110 should not be low from the size and installation space of top connection 110
In connector height lower limit Hd, in the hanging box section 100 of stock size, connector height lower limit Hd substantially 150mm.Such as Fig. 8
It is shown, at connector height lower limit Hd, 2.134 times of the substantially top connection load 200 of the front panel portion sharing part of the load 211, back plate
1.36 times of the substantially top connection load 200 of portion's sharing part of the load 212.
In conclusion in the present invention, the preferable height and position of the top connection 110 in hanging box section 100 is in radome fairing
Between upper level Hl (about 216mm) and connector height lower limit Hd (about 150mm).
<The position along course of top connection>
Top connection 110 sets the load performance to hanging box section 100 on wainscot 120 along the position in the course of aircraft
Have a significant impact.
Carried as shown in figure 9, engine saves 160 by preceding installation section 140 and rear installation, its position of centre of gravity installs section preceding
140 save the point of intersection of the respective extending direction of the load at 160 with rear installation, represent the load of engine with arrow 221 in fig.9
Lotus.And on the other hand, hanging box section 100 is then by top connection 110, center tap 150 and hound 170 by the load of engine
221 are delivered on wing or fuselage.Therefore, entirely hanging box section 100 can similarly be considered a cantilever beam, wherein in hair
Part in the same perpendicular of the load 221 of motivation is equivalent to the free end 231 of cantilever beam, and top connection 110, center tap
150 and hound 170 combination equivalent to cantilever beam root 232.
It can be seen that in the case of same load, the jib-length 233 that free end 231 is arrived between root 232 is shorter,
Then the internal stress of cantilever beam and deformation are smaller, and intensity is bigger, and structure is more stable.
But, it is increasingly complex to hang the load transmission form of box section 100, for example, installing section before having at free end 231
140 save 160 two load transmission positions with rear installation, there is top connection 110, center tap 150 and hound 170 at root 232
Load transmission position at three, wherein such as top connection 110 adds the carrying position of cantilever, and then improves its strength character, but
On the other hand, the setting of top connection 110 can also increase the load of local location, so as to reduce strength character.Therefore, it is necessary to right
Top connection 110 carries out more deep analysis along the position in course, to determine position of the optimal top connection of load performance along course
Put.
As Figure 10 adaptively shown in, the present invention have chosen four positions along course, and with existing hanging box section
Top connection 51 in 10 is compared and analyzed along the position Lt in course.This four positions are respectively:With existing hanging box section
Top connection 51 in 10 be in course position lo in same perpendicular, wainscot 120 centre position Lm, with engine
Load 221 is in the position Le in the same perpendicular and position Lf at preceding installation section 140.
Figure 11 shows the load corresponding to each course position in the form of radar map.Wherein, with 110,140,150,
160th, 170,121,122 signified radial alignments are represented in top connection 110, preceding installation section 140, center tap 150, rear installation section
160th, the load transmitted after hound 170, wainscot front panel portion 121 and wainscot in plate portion 122, the polygon pair of five closures
Should be in position Lt and above-mentioned top connection 110 to the present invention of the top connection 51 in existing hanging box section 10 along course
Four course positions Lo, Lm, Le and the Lf chosen, and the vertex of this five closed polygons then load at corresponding position
Size, wherein closer to circular, then it represents that corresponding load is smaller.
From the figure, it can be seen that for wainscot front panel portion 121, as top connection 110 is from the hanging box section of the prior art
The correspondence position of 10 top connection 51 constantly reduces towards preceding 140 movement of installation section, load therein, and for top connection 110
For, its load change does not follow the rule of increasing or decreasing then.As it can be seen that hanging box section 100 top connection 110 from existing
During the correspondence position of the top connection 51 of the hanging box section 10 of technology is moved towards preceding installation section 140, the load of different piece
Lotus changing rule simultaneously differs.In the present invention, the area enclosed using five closed polygons in the radar map shown in Figure 11
It is horizontal that the overall load of hanging box section 100 is assessed as index.
Table 1 shows the relative scale (wherein setting the area of Le as 1) of five closed polygon areas:
Table 1
Course position | Lt | Lo | Lm | Le | Lf |
Area | 2.16 | 3.77 | 2.70 | 1.00 | 2.13 |
It can be seen that at course position Le, the position in same perpendicular is in the load 221 of engine
Place, the overall load of hanging box section 100 are minimum, i.e. course position Le is the optimum position of hanging box section 100.
<Connection mode between the wall member of wainscot>
Below by by taking the plate portion of four pieces of triangles shown in attached drawing as an example, to describe each plate portion of composition wainscot 120
Between connection mode.
A kind of connection mode of wainscot 120 is that each plate portion is integrally connected together.For example, can be to an entire plate

Together.
For integrally formed wainscot 120, since each plate portion is formed integrally together, its strength character is most
It is good, but in maintenance, it is necessary to carry out installation and removal operation to whole wainscot 120, therefore it is not easy to assemble, and then be not easy to
Maintenance.
And for each plate portion is removably joined together wainscot 120, can be according to maintenance needs neatly
Selection dismounts any one or more therefore easy to repair in each plate portion.But, since each plate portion is by such as bolt
Deng component be removably joined together, therefore compared with the wainscot 120 being formed as one, by being detachably connected to
The strength character for the wainscot 120 that plate portion together is formed is remarkably decreased.
As the compromise of the wainscot 120 for integral type and the wainscot 120 removably assembled, the present invention carries
Go out the dismountable scheme in part.As shown in figure 12, plate portion 122, wainscot left plate portion 123, wainscot left plate portion 123 after wainscot
Be formed as one, and wainscot front panel portion 121 then by the components such as bolt removably with plate portion after wainscot 122, wainscot
The integrated component that left plate portion 123 and wainscot right panel portion 124 are formed links together, as shown in figure 12.
It is that obtained wainscot 120 is easier to repair by the way that wainscot front panel portion 121 is arranged to removably, and
Plate portion 122, wainscot left plate portion 123 and wainscot right panel portion 124 are integrally formed after wainscot, it can be ensured that by wainscot 120
Strength character maintain in certain level.
<Connection mode between wainscot and sidewall paneling>
In addition, can be integrally formed between wainscot 120 and sidewall paneling 130, or can also be removably
Link together, such as pass through the modes such as bolt.For angle easy to repair, wainscot 120 and side wall are preferably
Plate 130 is removably joined together.
<The mounting means of top connection>
