Technical field

The present invention relates to airplane structural design technology, the conductive seal method and conductive seal of specifically a kind of airplane hatch cover Band.

Background technique

Aircraft engine nacelle is fuselage side wall installation, and nacelle is made of skeleton and lid, and when engine maintenance needs Frequently open lid.Sealing for airplane hatch cover will not only adapt to the assembly environment and maintenance requirement of engine nacelle complexity, Also to meet its electromagnetic protection function, while it is also contemplated that structure is simple, it is reliable to install.Engine nacelle lid size is larger, It is influenced by the rebound of port cover structure sheet-metal formed, compactness is bad between lid and skeleton, and there are biggish uneven gaps, seriously Affect the electromagnetic protection ability of structure.General electromagnetic protection method domestic at present mainly using coating Conductive sealant and Conductive adhesive tape two ways is bonded in lid, coating Conductive sealant is chiefly used in infrequently demolition and maintenance position, and cure cycle It is longer.The mode of lid bonding conductive adhesive tape can be used for safeguarding position, but conductive adhesive tape is bonded in lid, to conductive adhesive tape The design of compression performance, resilience performance and mouth mount structure has very high technical requirements.It needs to design thus a kind of completely new, simple Single effective conductive seal method and conductive seal band, meet the electromagnetic protection requirement of airplane hatch cover.

Summary of the invention

It is an object of the invention to the demands according to problem of the existing technology and aircraft development production, provide one kind The conductive seal method and conductive seal band of airplane hatch cover.

A kind of conductive seal method of airplane hatch cover, contains airplane hatch cover and corresponding mouth frame, which is characterized in that have one Conductive seal band, the ontology of the conductive seal band are usual silicone rubber, guarantee that band has certain elasticity, adapt to engine The assembly technology of nacelle complexity, section are L shape, and L-shaped long side is installation fixed edge, and L-shaped short side is elastic packing side, In It is longitudinally inlaid with a metal reinforcing plates in the installation side of conductive seal band, reinforces the installation rigidity of band, guarantees band Normal mounting.One layer of conductive silicon rubber of periphery coating of the band formed simultaneously in usual silicone rubber, by conductive silicon rubber Layer coats usual silicone rubber band to form combined type conducting band, and conductive silicon rubber is contacted with body, keeps electromagnetism anti- Protective function.Above-mentioned conductive seal band installation side is fixed on to the lower surface of mouthful frame, makes the conductive silicon rubber of conductive seal band periphery The top height of glue-line and mouth frame following table face contact, the sealing edge of conductive seal band exports frame upper surface, and lid is crimped on mouthful frame, The elastic packing side of conductive seal band is by the lower surface compression seal of lid, while the conductive silicon rubber layer of conductive seal band periphery Lid and mouth frame are connected into conductive path.

A kind of conductive seal band, the ontology of the conductive seal band are usual silicone rubber, which is characterized in that the conduction is close The section for sealing band is L shape, and L-shaped long side is installation side, and L-shaped short side is sealing edge, in the sealing formed by usual silicone rubber A metal reinforcing plates, while one layer of conductive silicon of periphery coating of the band formed in usual silicone rubber are inlaid with interior longitudinal direction Usual silicone rubber band is coated by conductive silicon rubber layer and forms combined type conducting band by rubber.

The advantages of above-mentioned technical proposal, is: not changing original nacelle structure, it is only necessary to increase newly-designed L-type conductive seal Band can reach the purpose of electromagnetic protection, and have no effect to the frequent unlatching and the maintenance of engine of nacelle lid.

Present invention will be further explained below with reference to the attached drawings and examples.

Specific embodiment

Referring to attached drawing, the conductive seal band of the application is as shown in Figure 1, the ontology of the conductive seal band 1 is usual silicone rubber 2, it is L-shaped sealing band body that a section, which is made, by usual silicone rubber 2, and L-shaped long side is installation side, and L-shaped short side is close Edge sealing is longitudinally inlaid with a metal reinforcing plates 3 in the installation side for the band that usual silicone rubber is formed, in implementation, the gold Belonging to stiffening plate is preferably aluminium alloy plate, while one layer of conductive silicon rubber 4 of periphery coating of the band formed in usual silicone rubber, Usual silicone rubber band is coated by conductive silicon rubber layer and forms combined type conducting band 1.

Embodiment to the conductive seal of nacelle of airplane lid is implemented using the conductive seal band of the application, as Fig. 2, Fig. 3, Shown in Fig. 4, the installation side of conductive seal band 1 is fixed on the lower surface of nacelle of airplane mouth frame 5 by screw or rivet, makes conductive close Seal the conductive silicon rubber layer 4 of 1 periphery of band and the 5 following table face contact of mouth frame of nacelle of airplane, the top of the sealing edge of conductive seal band 1 It is higher by 5 upper surface of nacelle mouth frame, when nacelle lid 6 is closed, lid 6 is crimped on corresponding mouth frame 6, in 6 pressing force of lid Under double action with 1 screen resilience of conductive seal band, the elastic packing side of conductive seal band 1 is close by the lower surface compression of lid 6 Envelope, while lid 6 and mouth frame 5 are connected into conductive path by the conductive silicon rubber layer 4 of 1 periphery of conductive seal band, to reach winged The function of the electromagnetic protection of machine nacelle lid.
