Abstract
This utility model belongs to airplane structural design technology, relates to a kind of aircraft fuselage skin osculum and seals structure.It is included in the osculum (1a) on aircraft fuselage skin (1) lower surface；It is characterized in that: have a sealing mechanism being made up of flexure strip (3), rubber gasket (4) and rivet (5).The utility model proposes a kind of aircraft fuselage skin osculum and seal structure, can prevent the external water sources such as rainwater from pouring in down a chimney entrance cabin, and prevent dust, insecticide etc. from entering engine room inside, it is to avoid cabin is polluted, it is ensured that flight safety.
Description
Technical field
This utility model belongs to airplane structural design technology, relates to a kind of aircraft fuselage skin osculum and seals structure.
Background technology
Interior of aircraft is generally disposed with toilet facility, drinking water apparatus etc., when using these equipment, due to spilling, makes
Water droplet is fallen in cabin, converges in the position that body is relatively low, causes hydrops, and aircraft is when the rainy day flies or parks in addition, rainwater
May flow in cabin from the gap of the moving part such as door and window, lid, also be the main source causing aircraft hydrops.These amass
If water can not be discharged in time, easily cause corrosion and the damage of each system equipment of aircraft body structure part, thus shorten machine
Body life time, even jeopardizes aircraft safety.In order to prevent the internal hydrops of airframe, general way is to tie in body lower wall panels etc.
Osculum is drilled specially on component, when hydrops flows to underpart, outside just flowing out fuselage along these osculums, current
Aircraft osculum does not has sealing mechanism, and its shortcoming is: osculum makes engine room inside directly communicate with outside, makes nacelle exterior
Water have flow into engine room inside possibility, such as rainy day aircraft during take-off and landing, the hydrops on runway be just easy to by
Splash entrance cabin；Aircraft is when the rainy day parks, and rainwater also enters cabin readily along eyelid covering by osculum.Additionally, it is extraneous
Dust, insecticide etc. be likely to enter cabin by osculum, not only cabin is polluted, some systems may be set simultaneously
For damaging, endanger flight safety.
Summary of the invention
The purpose of this utility model is: proposes a kind of aircraft fuselage skin osculum and seals structure, in order to prevents rainwater etc.
External water source pours in down a chimney entrance cabin, and prevents dust, insecticide etc. from entering engine room inside, it is to avoid pollute cabin, it is ensured that
Flight safety.
The technical solution of the utility model is: a kind of aircraft fuselage skin osculum seals structure, is included in airframe
Osculum 1a on eyelid covering 1 lower surface, osculum 1a are positioned near fuselage architrave 2；It is characterized in that: have one by flexure strip 3,
Rubber gasket 4 and the sealing mechanism of rivet 5 composition；The l-shaped member that flexure strip 3 is made up of elastic metallic sheet material, in elasticity
On the lower surface of sheet 3 horizontal arm, bonding rubber gasket 4, has rivet hole, in fuselage architrave 2 on the upright arm of flexure strip 3
On also have rivet hole, by rivet 5, the upright arm of flexure strip 3 is riveted in fuselage architrave 2, rubber gasket 4 covers in draining
In the upper port of hole 1a, osculum 1a is sealed.
The utility model has the advantages that: propose a kind of aircraft fuselage skin osculum and seal structure, rainwater etc. can be prevented
External water source pours in down a chimney entrance cabin, and prevents dust, insecticide etc. from entering engine room inside, it is to avoid pollutes cabin, protects
Demonstrate,prove flight safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using method schematic diagram of the present utility model.
Detailed description of the invention
Below this utility model is described in further details, sees Fig. 1, Fig. 2.A kind of aircraft fuselage skin osculum is close
Seal structure, is included in the osculum 1a on aircraft fuselage skin 1 lower surface, and osculum 1a is positioned near fuselage architrave 2；Its feature
It is: by a sealing mechanism being made up of flexure strip 3, rubber gasket 4 and rivet 5；Flexure strip 3 is by elastic metallic sheet material
The l-shaped member made, bonding rubber gasket 4 on the lower surface of flexure strip 3 horizontal arm, on the upright arm of flexure strip 3
There is rivet hole, fuselage architrave 2 also have rivet hole, by rivet 5, the upright arm of flexure strip 3 is riveted in fuselage architrave 2,
Rubber gasket 4 covers in the upper port of osculum 1a, is sealed by osculum 1a.
Using method of the present utility model is: after a kind of aircraft fuselage skin osculum seals structure installation, when flying
Machine is shut down or in periodic maintenance on ground, and when having hydrops to need to discharge in cabin, attendant can use poker 6 at external fuselage
By the tap 1a jack-up rubber gasket 4 on aircraft fuselage skin 1 lower surface and the horizontal arm of flexure strip 3, can release
Hydrops；If after hydrops is discharged, can remove poker 6, the horizontal arm of flexure strip 3 and rubber gasket 4 recover under the effect of elastic force
Original state, can play the sealing process to tap 1a.
An embodiment of the present utility model, flexure strip 3 uses spring steel plate manufacture.Phosphorus bronze sheet, pyrite can also be used
Sheet or stainless steel substrates manufacture.
