Description
Technical field
The application belongs to airplane design technology, and in particular to the Drainage Design in airframe.
Background technique
In order to improve the corrosion protection of airframe, when aeroplane structure design, has considered waterproof as much as possible and has asked
Topic, but necessary gap clearance and build-up tolerance can still result in rainwater and enter internal body between components.How by ponding control
System is in limited region and is discharged in time, the problem that must be faced when being aeroplane structure design.Common discharge structure mainly by
The composition such as flange, drainpipe, ponding come together in lowest part under the effect of gravity, then exclude body by discharge structure.
Hu Jianfu et al. describes a kind of fuselage gas being made of flange, drainpipe in patent CN201520614574.8
Close top plate discharge structure appoints dawn et al. to describe a kind of fuselage floor with filter screen in patent CN201520429587.8
Discharge structure.
Summary of the invention
A kind of Drainage Design method of the application being designed to provide in airframe, can be by the ponding control of airframe
System is simple and reliable for structure in finite region.
A kind of design method of airframe internal drainage, containing base plate, drainage hole and water blocking stud, which is characterized in that
1) at the position of paddling of airframe, the base plate of body is designed to inclined-plane with angle, enable ponding along base plate from
So flow down；2) it is equipped with drainage hole in the suitable position of base plate, which connect with drainpipe；3) it is set in the side of drainage hole
A water blocking stud is counted, which guides ponding that airframe is discharged through drainage hole and drainpipe.
Above-mentioned water blocking stud can be the inflection structure for containing left stud and right stud, left stud and right stud
Angle region is the water conservancy diversion region of water blocking stud, drainage hole is designed at the nearly inflexion point on the inside of water blocking stud angle；
The load transfer structure of the water blocking stud and airframe can also be designed into a single integrated structure.Or by institute
The base plate design of the water blocking stud and airframe stated is into a single integrated structure.
The beneficial effects of the present application are as follows: 1) the application propose using airframe paddle position base plate inclination and gear
Ponding is come together in specified region by the guide functions of water stud, and in the mentality of designing of specified region setting drainage hole, makes to drain
It is simple and reliable for structure.2) the application proposes water blocking stud and cabinet load transferring structure designing integral mentality of designing, makes
Water blocking stud while intercepting rainwater, also can transferring structure load, improve structural stability, realize posting and water blocking one
Change design.
Attached drawing is described in further detail the application with reference to embodiments.
Detailed description of the invention
Fig. 1 is the signal of airframe discharge structure principle.
Fig. 2 is the signal of airframe discharge structure design principle.
Explanation: 1 base plate, 2 grades of water studs, 3 drainage holes, 4 inflexion points, 5 left studs, 6 right studs, 7 drainings is numbered in figure
Pipe, 8 horizontal planes
Specific embodiment
Referring to attached drawing, a kind of design method of airframe internal drainage, containing base plate 1, drainage hole 3 and water blocking stud 2,
At the position of paddling of airframe, the base plate 1 of body is designed to inclined-plane with angle, enables ponding along base plate nature
It flows down；It is equipped with drainage hole 3 in the suitable position of base plate 1, which connect with drainpipe 7；It is set in the side of drainage hole 3
A water blocking stud 2 is counted, which guides ponding that airframe is discharged through drainage hole 3 and drainpipe 7.
Above-mentioned water blocking stud 2 can be the inflection structure for containing left stud 5 and right stud 6, and left stud 5 and the right side are vertical
The angle region of muscle 6 is the water conservancy diversion region of water blocking stud, and drainage hole 3 is designed at the nearly inflexion point 4 on the inside of water blocking stud angle
Place；
It, can also be into a single integrated structure by the load transfer structure design of the water blocking stud 2 and airframe in implementation.
Or the base plate 1 of the water blocking stud 2 and airframe is designed into a single integrated structure.
The application devises a kind of water blocking stud, and for controlling the ponding of airframe in finite region, structure is simple
Reliably.Water blocking stud while intercepting rainwater, also can transferring structure load, improve structural stability, realize posting and gear
Water integrated design.
Fixation at least two schemes between the water blocking stud 2 and base plate 1, will describe respectively below.
Scheme one: water blocking stud 2 and the whole machining of base plate 1.The program is suitable for there also is provided it on base plate 1
The structure of his boss, stud.Woollen size needed for the design scheme will not both increase processing because increasing water blocking stud 2, also
The fastener connection between water blocking stud 2 and base plate 1 is eliminated, while 2 rigidity of water blocking stud being integrally machined is more preferable,
1 stability of base plate can preferably be enhanced.
Scheme two: water blocking stud 2 and base plate 1 are separately fabricated.It is one without other boss, stud for base plate 1
Slab construction, inflection stud 2 can be separately fabricated with sheet metal component.Connected on the water blocking stud 2 and base plate 1 of metal plate manufacture with fastener
It connects, and carries out fillet sealing with sealant 10.The design scheme reduces the woollen size and machining when processing base plate 1
Amount is conducive to reduce cost when part batch produces, but increases the connection of the fastener between water blocking stud 2 and base plate 1 and close
Envelope processing.
