Abstract

A submarine has a pressure hull (20) which includes a number of adjoining transparent viewing sections (21 and 22) in the shape of truncated spheres. The sections (21 and 22) are clamped to a body section (23, 24) by a cage (40) and tension rods (44) which pass slidably through a thrust ring (38) interposed between the transparent sections. Access to a passenger compartment within the pressure hull is obtained via a hatch (32) in a mid section (23). The pressure hull is housed in an external hull designed for surface cruising. Ballast tanks are formed between pressure hull and the external hull, and the tie rods pass through low pressure seals to pivotal anchorage points within the ballast tanks.

Description

SUBMERSIBLE VESSELS
TECHNICAL FIELD OF THE INVENTION
This invention relates to submersible vessels such as (without prejudice to the generality) submarines.
BACKGROUND
It has long been known that hollow submersible bodies of spherical shape are capable of withstanding approximately twice the external pressure of a substantially cylindrical body of comparable diameter and wall thickness. Submersible vessels having pressure hulls formed from a number of interconnected sections in the form of truncated spheres are already known, as disclosed for example in GB 279 483, GB 2 223 716 A and US 5 477 798.
In submersible vessels, windows or viewports may also be formed with a part-spherical shape for strength. A common material used in the manufacture of such viewports is acrylic plastics, since this has a refractive index close to that of seawater and therefore minimises visual distortion. However, the viewport mounting must be capable of maintaining an effective seal over a wide range of external pressures and operating temperatures. In a known form of mounting for part-spherical viewports, a radial face of the viewport surrounding a circular opening is seated against a part- conical surface with provision of suitable seals. The viewport is held in position by a clamping ring which holds a peripheral edge of the viewport against the part-conical seat. Such arrangements may be used to effectively secure viewports of substantial size.
In general, increasing the angle of the opening reduces the range of hydrostatic pressures which the mounting can handle. On the other hand, reducing the angle of the opening restricts the internal space. In pressure hulls which include a viewing area formed from a number of adjoining part-spherical transparent sections this would place a restriction on the size of the internal compartment.
The present invention seeks to provide a new and inventive form of submersible vessel having a number of adjacent part-spherical transparent sections in which the size of the internal compartment is maximised whilst maintaining an effective seal throughout a wide range of external pressures.
SUMMARY OF THE INVENTION
The present invention provides a submersible vessel having a pressure hull which includes:
- a body section,
- a substantially transparent part-spherical end section having a single opening, and
- at least one substantially transparent part-spherical intermediate section having a pair of openings and being disposed between the end section and the body section such that the said sections provide a common internal compartment; characterised by a cage partially surrounding the end section; and a plurality of tension elements connecting the cage to the body section, disposed externally of the intermediate section or sections.
The cage preferably comprises a tension ring and a plurality of anchoring members projecting from the tension ring and each connected with a respective tension element.
In a preferred arrangement a thrust member is interposed between adjacent transparent sections, and the tension elements pass slidably through the thrust member. The thrust member may thus locate the tension elements whilst balancing the sealing pressures on opposite sides of the thrust member.

DETAILED DESCRIPTION OF THE DRAWINGS
Fig.s 1 to 3 show a vessel which is commonly referred to as a submarine. The vessel is capable of both surface and sub-surface use. The vessel has an external hull 10 which is shaped for surface cruising, having a leading bow end 11 and an aft end 12 with a propeller 15. During surface use the propeller 15 may be driven by an internal diesel engine to provide economical use over a considerable distance, but during dives the propeller may be driven by an internal electric motor powered by a rechargeable battery. The external hull is surmounted by a deck area 16, which is surrounded by an upstanding safety wall 17. The bow end 11 is provided with a transparent window 18 which extends on both sides of the vessel.
The external hull 10 contains an internal pressure hull 20, shown in Fig.s 4 to 7, which is designed to withstand the high external pressures encountered during sub-surface dives. Starting at the bow end, the pressure hull includes a bow section 21 , an intermediate section 22, a mid section 23, and an aft section 24. The bow and intermediate sections 21 and 22 are both formed of transparent acrylic plastics (other suitable transparent materials could be used, of course) whereas the mid and aft sections 23 and 24 form a metal body section, both being generally of cylindrical shape with circumferential, axialiy-spaced reinforcing rings 25. The aft section 24 is closed by a part-spherical end 26 and is joined to the mid section 23 by conventional flange seals 27. Referring back to Fig. 1, the transparent sections 21 and 22 form part of an internal passenger compartment 30 within the pressure hull, which extends into the mid and aft sections. The passenger compartment is accessed through a cylindrical access hatch 32 which passes through the top of the mid section 23 into the deck area 16 and is closed during dives by a pressure cover 33. The remainder of the body section 23, 24 outside the passenger compartment contains service equipment such as the drive motors, batteries, air supply equipment etc.
A space is formed between the body section 23, 24 of the pressure hull and the external hull 10, containing one or more enclosed ballast tanks which are part-flooded to control the diving depth. The transparent sections 21 and 22 of the pressure hull are disposed behind the bow window 18 so that the external environment is clearly visible to people in the passenger compartment. The intervening space between the sections 21 , 22 and the window 18 may be flooded to reduce pressure forces on the window 18 during dives.
Returning to Fig.s 4 to 7, the bow section 21 is formed as a truncated sphere with a single opening subtending an angle C at the centre of the sphere of about 120°. The intermediate section 22 is similarly formed as a truncated sphere of the same radius, but this section has two opposing openings each subtending the same angle (about 120 degrees) from the centre of the sphere. A metal thrust ring 38 is interposed between the transparent sections 21 and 22 whereas the mid section 23 is provided with a ring-shaped seat 39 against which the intermediate section 22 is held. A cage 40 is shaped to partially surround the bow section 21 , in contact with its external surface. The cage includes a tension ring 41 and a number of anchoring members 42 which project aft from the tension ring, each terminating, adjacent to the thrust ring 38, in a pair of spaced pivot plates 43. A respective tension rod 44 is pivotally connected with each of the anchoring members by means of a pivot pin inserted through the plates 43. The tension rods 44 extend externally of the intermediate section 22 substantially parallel to the fore-aft axis of the pressure hull, each terminating in a clevis 45. Each of the tension rods 44 is pivotally secured to the mid section 23 by means of a respective external anchorage plate 46. The two uppermost tension rods are secured to circumferential anchorage plates on the access hatch 32 whereas the remaining plates 46 project radially from the mid section. The anchorage plates 46 are all located within the ballast tanks, but the tie rods pass slidably through low pressure seals at the point of entry 47 into the ballast tanks.
The cage 40 and tension rods 44 clamp the transparent sections 21 and 22 to the mid section 23. Eight tension rods are provided in the present embodiment. However four of the rods are disposed at the upper region of the transparent sections 21 and 22 and four are disposed at the lower region. The rods 44 do not therefore impede the side view from the passenger compartment but the balanced arrangement enables the cage 40 to apply even clamping pressure to the transparent sections. It will also be noted that a base platform 48 projects forwardly from the mid section 23 below the transparent sections 21 and 22, which supports the transparent sections during assembly and maintenance of the pressure hull.
The thrust ring 38 is provided with outwardly-projecting flanges 49 through which the tension rods 44 are slidably inserted to ensure accurate circumferential and radial location of the rods. Fig. 8 shows how the thrust ring 38 is interposed between the two transparent sections 21 and 22 whilst Fig. 9 shows how the intermediate section 22 is held against the seat 39 of the mid section 23. The adjacent opening of each section is surrounded by a radially-extending face 50 which is supported against a respective part-conical seat 51. The outer circumferential limit of each seat is formed by an abutment face 53 which projects substantially perpendicularly from the seat 51. (See inset detail of Fig. 8.) - The adjacent corner of the transparent section, between the radially-extending face 50 and the external face 54, is formed with a short inclined face 55. An O-ring seal 56 is enclosed between the seat 51 , the abutment face 53 and the inclined face 55 so that, when the rods 44 are correctly tensioned, the O-rings are sealingly compressed between these three faces. During a dive the hydrostatic pressures on the external faces of the transparent sections are resisted by the cage 40 and tension rods 44 so that the radial faces 50 are held against the part-conical seats 51. Since the thrust ring 38 is slidably located on the tension rods 44 the compression forces are equally divided between the three seats 51. As the external pressure increases the faces 50 may eventually slide radially inwards on the seats 51 but as long as the O-rings remain compressed an effective pressure seal is maintained.
In larger vessels which are intended to accommodate a larger number of passengers the pressure hull may include two or more intermediate sections 22 with a similar thrust ring 38 interposed between each adjacent pair of sections.
With the arrangement described the size of the passenger compartment is maximised whilst maintaining effective seals over a wider range of external hydrostatic pressures. The high pressures to which the seals may be subjected during a dive remain substantially balanced throughout the intended operating range.
It will be appreciated that the features disclosed herein may be present in any feasible combination. Whilst the above description lays emphasis on those areas which, in combination, are believed to be new, protection is claimed for any inventive combination of the features disclosed herein.
