Abstract
A submarine structure comprises a plurality of identical truncated spherical modules 10-13 of composite material joined together. The structure leads to a strong overall arrangement and the adoption of composite materials leads to cheapness. Since relatively small modules are involved any inherent weaknesses in the modules can be corrected. Metal matrix materials or filament-wound plastics can also be used. Attachment flanges 14A, 14B are provided and these may be used to support an "exoskeleton" as required for greater rigidity of the complete submarine. <IMAGE>
Description
ss QubmersiLle Body The e invention relates to submersible bodies and particularly, though not exclusively, to submarine pressure hulls.
In order to reduce weight and manufacturing costs of submarines and other submersibles it is desirable to consider use of composite materials. This approach, however, for large bodies is difficult and expensive.
The object of the present invention is to provide a submarine body suitable for fabrication with current composite materials.
The invention provides: a subgersible body comprising a plurality of identical modular shell coroponents formed as truncated spherical segments and provided with means to assentle adjacent segnentsr the segments being made of a composite material.
The composite material may be of fibre reinforced plastics or metal.
Advantageously each truncated spherical shell segment is provided with flanges for modular assembly. The flanges are preferably formed such that they serve as stiffening melrbers for the subnersible assembly of segments.
When made of plastics the shell modules may be filament-wound and the filaments used may be glass, carbon, boron, aluminium, silicon carbide or other suitable high strength material. Alternatively the modules may be compression moulded. When using a metal matrix, a liquid metal infiltration process is preferably used.
A visco-elastic material may conveniently be incorporated between the modular segments in order to inhibit the transmission of structureborne noise. The flange joints between adjacent modular segments may be sealed by means of "O" rings.
The invention will now be described by way of example only with reference to the accompanying Figure 1 which is a schematic cross section through a composite material submarine pressure hull. The hull comprises a number of identical part-spherical segments 10-13, provided with flanges 14S, 14B for asseTsbly. Although not shown, the flanges 14A and 14B may be joined together by conventional means such as by bolts, clamps or adhesive bonding. WO" ring seals are provided between flanges 14A and 14B. There may also be provided at least one layer of viscelastic material between the flanges 14A and 14B such that vibrations or structure-borne sound in the hull are absorbed.
Segments 10-13 employ higkstrength (eg glass, carbon, boron, alumina or silicon carbide) fibres in a polymer or metal matrix. Fabrication of segments is by filament winding or compression moulding in the case of a polymer matrix, or by liquid metal infiltration or an equivalent process in the case of a metal matrix. Considerable economy should be achieved by constructing a pressure hull from a series of small, repeated modules.
Stress concentrations in the region of joints between segments are minimized by varying the shell thickness, optimizing fibre orientation and adjusting the flange geometry.
The flanges 14Ar 14B at segment boundaries may be used to mount an external shell or casing, which might be longitudinally framed in order to enhance longitudinal strength and stiffness of the hull, eg under conditions of explosioninduced whipping.
