The specific embodiment
As Fig. 1, shown in 2, the present invention is with the flexible bottom of overcoat, comprise base plate 11 and sidewall 12, base plate 11 and sidewall 12 are made by polyamide fibre/rubber blanket material, and base plate 11 and sidewall 12 form tubbiness, base plate 11 inner surfaces are provided with strengthening course 13, strengthening course 13 is hard foam, as shown in Figure 3, on strengthening course 13, be bonded with successively from inside to outside butyl offset plate 14, aramid fiber adhesive plaster 15, the surface, inboard of aramid fiber adhesive plaster 15 and sidewall 12 is pasted with screen layer 16, screen layer 16 adopts electromagnetic shield cloth, screen layer 16 external pastings have butyl adhesive plaster 17, the thickness of butyl offset plate 14 is 0.5mm, the thickness of aramid fiber adhesive plaster 15 is 1.0mm, butyl adhesive plaster 17 thickness are 0.3mm.
Between butyl offset plate 14 edges and base plate 11, be bonded with the first crimping protective plate 21, the first crimping protective plate 21 is ring-type, the first crimping protective plate 21 is hydrogenated butyronitrile offset plate, between aramid fiber adhesive plaster 15 edges and base plate 11, be bonded with the second crimping protective plate 22, the second crimping protective plate 22 is ring-type, the second crimping protective plate 22 is hydrogenated butyronitrile offset plate, the part external pasting matcoveredn 23 of close the second crimping protective plate 22 on the second crimping protective plate 22 and aramid fiber adhesive plaster 15, this protective layer 23 is ring-type, protective layer 23 adopts aramid fiber adhesive plaster, first, the second crimping protective plate 21, 22 thickness is 0.6mm, the thickness of protective layer 23 is 1.0mm, at butyl offset plate 14 and aramid fiber adhesive plaster 15 edges, arrange respectively first, the second crimping protective plate 21, 22, and first, the second crimping protective plate 21, 22 all adopt hydrogenated butyronitrile offset plate, the performance of hydrogenated butyronitrile offset plate antiscour is better than butyl offset plate 14 and aramid fiber adhesive plaster 15 but cost is higher, therefore only at crimping seam crossing, use, at high temperature, under the bad working environments that high-pressure gas washes away, can prevent from raising at the edge of butyl offset plate 14 and aramid fiber adhesive plaster 15, at the second crimping protective plate 22 and aramid fiber adhesive plaster 15 external pasting protective layers 23, can further prevent that aramid fiber adhesive plaster 15 from raising.
For increasing the deformability with the flexible bottom of overcoat, make to launch load and be transmitted to better ground, to reduce and act on the additional load amount on flat pad, the longitudinal cross-section of sidewall 12 is S shape, sidewall 12 tops have connecting hole 121.
As shown in Figure 4, the present invention is connected in to just room 31 bottoms with the flexible bottom of overcoat, between the surface of the bottom of base and launching level ground 32, leave spacing, during MISSILE LAUNCHING, high-temperature high-pressure fuel gas acts on base inner surface, base distortion, sink with launching level ground 32 surfaces between contact, most of combustion gas load is passed to launching level ground 32, high-temperature high-pressure fuel gas contacts with susceptor surface, because susceptor surface is provided with strengthening course and butyl adhesive plaster 17, aramid fiber adhesive plaster 15 and butyl offset plate 14, butyl adhesive plaster 17, aramid fiber adhesive plaster 15, butyl offset plate 14 forms overcoat, preventing that high-temperature high-pressure fuel gas from directly acting on base plate and sidewall causes damage to base plate and sidewall, and because strengthening course is arranged at overcoat inboard, when increasing base rigidity, avoid producing under the effect of high-temperature high-pressure fuel gas damaged, prevent that damaged fragment is to being launched the adverse effects such as deposits yields collision, in first room under the combustion gas souring of HTHP, flexible bottom with overcoat may produce partial fracture, but can not produce large fragment, because butyl offset plate 14 is positioned at the most inboardly, butyl offset plate and top layer are that the base plate compatibility of elastomeric material is better, are difficult for throwing off.
The above embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
