Abstract

The invention belongs to the technology of design of airplane structural sealing protection, and relates to a rainproof sealing method for a shipboard airplane body under the high-corrosion marine environment. The rainproof sealing method comprises the following three aspects of (a) sealing opposite joints of skins, (b), sealing a buccal frame, and (c) sealing connecting pieces. Sealing measures are introduced in the assembling process, and a sealant is smeared on the position between structural interlayers of a potential leakage area, and intra-joint sealing of the structural interlayers is achieved; rainwater is prevented from permeating to the structural interlayers, and structural corrosion of the airplane body structure from beginning of the interlayers is avoided.

Description

A kind of high corrosion marine environment lower body weather seal method on warship

Technical field

The invention belongs to aircaft configuration sealing protection designing technique, relate to a kind of high corrosion marine environment lower body weather seal method on warship.

Background technology

For avoiding the corrosion impact brought housing construction that rains, usual land airplane, after completing assembling, can be smeared aquaseal in the potential leakage point inside such as covering joint, mouth frame place, attaching parts place of body and carry out weather seal.Such existence problem, aquaseal is smeared in inside no doubt makes rainwater enter internal body, but rainwater can be seeped between decker sandwich along the gap of body surface.Because the environment for use of land airplane compares carrier-borne aircraft drying, such design can not bring problem, and for long-term under moistening height corrosion marine environment the carrier-borne aircraft of taxes and corvee, a kind of means must be taked to prevent rainwater from infiltrating decker sandwich, avoid from interlayer, cause housing construction to corrode.

Summary of the invention

Technical matters to be solved by this invention is: provide a kind of high corrosion marine environment lower body weather seal method on warship, to realize preventing rainwater from infiltrating carrier-borne aircraft housing construction interlayer with fuselage surface gaps, avoid from interlayer, cause housing construction to corrode.

On a kind of warship, high corrosion marine environment lower body weather seal method, is characterized in that: described weather seal method comprises following three aspects: a) sealing of covering joint; B) sealing at mouth frame place; C) sealing at attaching parts place:

A) sealing of covering joint

Before installation two pieces of coverings 1, first brush one deck HM109 aquaseal 7 on the binding face of band plate 3 and two pieces of coverings 1, after completing assembling, at each brush in band plate 3 both sides HM109 aquaseal 5; The last HM109 aquaseal 6 brushed two-layer 1:1 and dilute outside band plate;

B) sealing at mouth frame place

Before covering 1 with mouth frame 3, first brush one deck HM109 aquaseal 7 on mouth frame 3 with the binding face of covering 1; After completing assembling, at mouth frame 3 both sides and place's brush HM109 aquaseal 5 that sink; Outside covering 1 with mouth frame 3 junction, finally brush the HM109 aquaseal 6 that two-layer 1:1 dilutes;

C) sealing at attaching parts place

Before installation covering 1, first brush one deck HM109 aquaseal 7 on framing member 4 with the binding face of covering 1, after completing assembling, at each brush in framing member 2 two ends HM109 aquaseal 5; The last HM109 aquaseal 6 brushed two-layer 1:1 and dilute outside framing member.

This method and continental rise type airframe seal topmost improvement and are: in fitting process, introduce seal approach, aquaseal is smeared between the decker sandwich in potential seepage region, sealing in the seam of implementation structure interlayer, prevent rainwater from infiltrating decker sandwich, avoid from interlayer, cause housing construction to corrode.

Wherein, 1-covering, 2-band plate, 3-mouth frame, 4-framing member, 5-HM109-1 sealing joint strip, the HM109-1 aquaseal of 6-two-layer 1:1 dilution, the interior HM109-1 aquaseal of 7-seam.

Detailed description of the invention

Be described further below in conjunction with the detailed description of the invention of accompanying drawing to this method.

A) sealing of covering joint

See Fig. 1, its main method of operation is as follows: before installation two pieces of coverings 1, first brush one deck HM109 aquaseal 7 on the binding face of band plate 3 and two pieces of coverings 1, after completing assembling, at each brush in band plate 3 both sides HM109 aquaseal 5; The last HM109 aquaseal 6 brushed two-layer 1:1 and dilute outside band plate;

B) sealing at mouth frame place

See Fig. 2, its main method of operation is as follows: before covering 1 with mouth frame 3, first brush one deck HM109 aquaseal 7 on mouth frame 3 with the binding face of covering 1.After completing assembling, at mouth frame 3 both sides and place's brush HM109 aquaseal 5 that sink.Outside covering 1 with mouth frame 3 junction, finally brush the HM109 aquaseal 6 that two-layer 1:1 dilutes;

C) sealing at attaching parts place

See Fig. 3, its main method of operation is as follows: before installation covering 1, first brush one deck HM109 aquaseal 7 on framing member 4 with the binding face of covering 1, after completing assembling, at each brush in framing member 2 two ends HM109 aquaseal 5.The last HM109 aquaseal 6 brushed two-layer 1:1 and dilute outside framing member.
