Abstract
Protective apparatus for storing missiles on a ship, from which the missiles may be directly launched vertically, comprises a plurality of mutually adjacent, elongate protective containers (6, 7, 8, 9, 10, 11) mounted with their respective longitudinal axes vertical and each adapted to support vertically therein a missile (12, 13, 14) in a launch disposition. The upper end of each container has an opening through which the missile can pass during launch, the opening normally being closed by an openable closure (18, 19). The respective lower ends of the containers open, via respective exhaust gas valves, into a common plenum chamber (15) having an exhaust gas vent (16, 17) to atmosphere. Each container has an associated quenching fluid pipeline (23) provided with a quenching fluid valve (22), the valve (22) normally being closed but being automatically and instantaneously openable in response to penetration, by an externally originating projectile or fragment, of a wall of a container whereby pressurised quenching fluid flows into that container to douse or prevent fire or explosion.
Description
1337~64 Missile Storage Apparatus This invention relates to missile storage appartus and more particularly to apparatus for storing missiles on naval ships.
Missile propellants and warheads comprise combustible and/or explosive materials which are not particularly hazardous when handled and stored normally but which may be ignited by a substantial and/or sustained rise in temperature. The storage of missiles on ships is a long standing problem; the storage apparatus is clearly liable to "attack" either deliberately by an aimed projectile or incidentally by a fragment from, for example, a nearby explosion. Propellants and/or warheads may ignite when struck by such a projectile or fragment resulting in an explosion or fire.
Accordingly, it has hitherto been customary to store ships' missiles below the waterline, thereby providing some degree of protection, the missiles being moved up to the firing deck as and when desired. Typically, the firing deck supports a number of launch tubes into each of which a missile is loaded prior to firing whereupon vulnerability to "attack" by projectiles or fragments is immediately and substantially increased. In addition, the launch tubes confine the missiles which confinement could actually ~, 1~37961 exacerbate the effects of ignition caused by a projectile or fragment attack.
An object of the present invention is to provide protective apparatus for storing missiles or the like on ships from which apparatus the missiles may be directly launched vertically as and when desired.
According to the present invention there is provided apparatus comprising a plurality of mutually adjacent, elongate protective containers mounted with their respective longitudinal axes vertical and each adapted to support vertically therein a missile or the like in a launch disposition, the upper end of each container having an opening through which the missile can pass during launch, said opening normally being closed by an openable closure and the lower end of each container opening, via exhaust gas valve means, into a common plenum chamber having exhaust gas vent means to atmosphere, said containers having respective quenching fluid inlets and quenching fluid valve means associated therewith, said quenching fluid valve means normally being closed but each being automatically and substantially instantaneously openable in response to penetration, by an externally originating projectile or fragment, of a wall of its associated container thereby enabling quenching fluid to flow into that container through its quenching fluid inlet.
Preferred features and a preferred apparatus of the invention will now be described, by way of example only, with reference to the accompanying drawing which is a schematic cut-away perspective view of the apparatus loaded with vertical launch missiles.
1~37964 Referring to the drawing, the apparatus of the invention, designated generally by reference numeral 1, is shown rigidly mounted substantially between the upper deck 2 and a lower deck 3 of a warship. The apparatus 1 comprises two sets 4 and 5 of four elongate, vertically disposed containers, the six containers visible in the drawing being designated by reference numerals 6 to 11 respectively.
Each container 6 to 11 is in the form of an enclosure comprising four elongate wall sections that are arcuate in plan view and which may be strengthened by one or more external metal members. These sections, in the case of container 9, are designated 9~, gn~ 91~l and 9"" and are preferably formed of a fibre reinforced resin/ceramic/fibre reinforced resin laminate, adjacent sections being bonded together. A container made of such a laminate is generally able to contain fragments resulting from explosion of the motor(s) of the missile stored therein thereby minimising the chance of such a fragment reaching, and initiating ignition of, the motor(s) of a missile stored in an adjacent container of the apparatus. A preferred laminate comprises a loosely needled blanket of ceramic fibres (for example that available under the trade mark "FIBREFRAX~) sandwiched between layers of glass fibre mat embedded in an epoxy resin. Preferably, each section 9' etc is produced by longitudinally cutting a tube formed of said laminate. The four vertices of the hollow space formed by the sections accommodate the wings of the missile, three of which are designated by reference numerals 12, 13 and 14, mounted in each container in a vertical launch disposition. Integral with the laminate sections 9~, gn~ 9ll1 and 9nl' is a fragment or projectile penetrating detector means the nature and purpose of which are described more fully below.
1~37964 The respective lower ends of the containers 6 etc communicate , via respective one-way flap or other valves (not shown) with a plenum chamber 15 that is provided with an exhaust duct 16 having an open upper end 17. Each of the valves is normally closed but immediately (eg about 0.1 second) prior to firing of a missile, the valve associated with the container 6 etc containing the missile to be fired is opened and automatically closes preferably immediately after the missile has left its container. Closure may be effected by, for example, the action of a return spring, the rate of closure depending upon the rate of exhaust gas pressure decay within the container. Thus, each valve permits, during firing of a missile, exhaust gas from the missile to pass into the plenum chamber 15 whence it passes to atmosphere through the duct 16. On the other hand, such valve in its normal, closed, position serves to prevent exhaust gas from one missile entering, via the plenum chamber 15, a container housing another missile which could otherwise result in damage to or even accidental ignition of that other missile.
The upper end of each of the containers 6 etc is normally closed by an inner "fly through" membrane and an outer protective lid. In the drawing, outer lid members 18, 19 serve to close off the two sets of containers 4 and 5 respectively. Each lid member 18, 19 is pivotably mounted and is movable between a closed and an open n launch~
position. In the drawing, the lid member 18 is shown in its closed position whilst the lid member 19 is shown in its open, "launch" position. Regarding the open lid member 19, it will be seen that its upper surface 20 abuts part of the open end 17 of the exhaust duct 16 and serves to deflect exhaust gas from missile 13 (shown as being launched) away from the initial flight path of the missile. This ensures that the exhaust gas, which issues from the duct 16 at a very high velocity, will not in any way affect the direction of flight of the missile as it is being launched. However, a separate deflecting member may be provided to fulfil this function. Each lid 18, 19 is provided with four blow out panels, one of which is designated 21, one positioned above the upper end of each container. These panels serve to relieve excess gas pressure within the container in the event of accidental ignition of a missile during storage when the lid member 18 or 19 is shut.
Each "fly through" membrane, one of which is designated 19', comprises expanded polystyrene sheet material having lines of weakness and which, during launch, will merely be penetrated by the missile. The membranes serve to prevent sea water, for example, entering the containers when the lid members 18 or 19 are open. Further, as it is intended that the missiles will be loaded into their respective containers in a factory and then be transported to the ship in question, it is desirable for the containers to be sealed against the ingress of moisture and other matter during transport and storage. The membranes 19' etc also serve that purpose and, for the same reason, the base of each container 6 etc, between the one way valve and the bottom of the missile, is provided with a membrane (not shown), for example of an aluminium/chlorosulphonated polyethylene/aluminium laminate, which membrane, during launch, will be destroyed by the exhaust gas. During transport and storage, the containers 6 etc may be slightly pressurised, for example by nitrogen, to help prevent ingress of moisture. Further, during transport and storage, the ends of each container 6 etc may be provided with protective end caps made, for example, of the afore-mentioned laminate, the caps being removed prior to loading of the containers, for example by crane, into position on the ship.
133796~
As already indicated, the walls of each missile container incorporate over substantially their entire area a detector (not shown) that is capable of detecting penetration thereof by a fragment or projectile. The detector associated with each container may be such as to detect penetration immediately after it has occurred but detection preferably occurs actually during the course of penetration. Any suitable type of detector may be employed but preferably it is in the form of a number of closely spaced (eg 2mm) electrically conductive wires, for example of copper, embedded in a sheet matrix of, for example, polypropylene. The sheet matrix may conveniently be laminated to either of the resin layers of the wall sections 9' etc of the containers. The wires are incorporated in an electrical circuit and, when a wire is broken or, alternatively, when two adjacent wires are shorted together by a fragment or projectile during passage thereof through the detector, the circuit provides an electrical signal that opens, via control circuitry, a fluid flow control valve (reference numeral 22 in the case of container 9) located in a quenching liquid pipe line (reference numeral 23 in the case of container 9) to which quenching liquid is supplied under pump pressure from a reservoir. The valve normally is closed and prevents the pressurised quenching liquid from entering its associated container. However, when the valve opens in response to said signal, quenching liquid, typically water, flows rapidly into the affected container and serves to prevent or quench an ensuing fire or explosion.
Each container is provided with a quenching liquid inlet at its upper end. The inlet associated with container 9 is designated by reference numeral 24 and is positioned such that quenching liquid entering the container will first t3373~
douse the most dangerous part of the missile, namely the war-head. One or more further inlets may, however, be provided at any desired location.
In the event of penetration of one or more of the containers occurring, the quenching liquid pumped into the container(s) will, of course, descend to the bottom of the container(s) and may, if the aluminium laminate membrane referred to earlier becomes damaged, flow via the flap or like valve(s) into the plenum chamber 15. Since, in the particular embodiment shown in the drawing, it is intended that penetration and quenching of, say, a single container should nevertheless leave the remaining containers and their missiles serviceable, quenching liquid that accumulates in the plenum chamber 15 is pumped out via conduit 25 so as to leave the exhaust gas flow passageways free for the purpose of further launchings. Preferably, an additional, normally open, valve, such as a solenoid valve, may be associated with each inlet/quenching fluid valve and that, during quenching, will automatically stop the flow of liquid through the inlet after, say, a period of three minutes but that will re-open if there is a further rise of temperature within the container, and so on. This will prevent the supply of unnecessarily excessive amounts of quenching liquid to the container(s) in question.
The lower part, designated 26, of the apparatus represents a control and monitoring panel from which, inter alia, opening and closing of the lid members 18, 19, missile launching and manual override of the quenching liquid con-trol valves may be effected In this respect, items 27 and 28 represent interfaces between the missile computer equipment and the ships computer equipment and item 29 represents an aerial for sending/receiving signals to and from the missile during launch.
