BACKGROUND
1. Field
This application relates generally to a multi-missile carriage and launch guidance module for supporting the carriage and guiding the launch of a plurality of missiles.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
Surface-to-surface missile launch systems are known to include canisterized missiles. FIG. 2 shows such a system installed in a surface vessel with deck launch bay doors open to show canister-housed (canisterized) missiles carried by missile carriage and launch modules received in launch bays of the surface vessel. Because each missile canister includes its own systems for supporting, communicating with, and controlling the environment of its housed missile, the canisters comprise a significant portion of the launch system's mass. This becomes a liability in that it reduces the total number of missiles that may be carried by a combat system or that may be loaded into a ground, air, or sea transport for resupply.
SUMMARY
A multiple missile carriage and launch guidance module is provided, which comprises a plurality of missile launch rails, each one of which is configured to carry and guide the launch of a missile. A common missile carriage wall may carry the missile launch rails in respective positions and orientations that allow for missile carriage and launch from the rails.

DETAILED DESCRIPTION
A multiple missile carriage and launch guidance module is generally shown at 10 in FIGS. 1, and 3-8. The module 10 may include eight generally parallel missile launch rails 12 as best shown in FIG. 7, although, in other embodiments, any number of rails 12 may be included. The rails 12 may, for example, be of the type used in an M299 Missile Launch System. As shown in FIGS. 5 and 6, each rail 12 may be configured to carry and guide the launch of a missile 14, such as, for example, an AGM-114L Longbow HELLFIRE missile.
As best shown in FIGS. 7 and 8, the module 10 may also include a common missile carriage wall 16 carrying the missile launch rails 12 in respective positions and orientations allowing for missile carriage and launch from the rails 12. The common missile carriage wall 16 obviates the need to accommodate individually canisterized missiles, reducing module weight and footprint by increasing missile 14 packing density in, for example, an Littoral Combat Ship Vertical Launch System LCSVLS application.
As shown in FIGS. 8 and 9, the carriage wall 16 may comprise a carriage wall core 17 defined by generally parallel spaced-apart front and back structural skins 18, 20 of the carriage wall 16. The skins 18, 20 may be joined together around respective peripheral edges by fasteners 22, and may include a rubber O-ring gasket 24 received in a channel 26 formed around the peripheral edge of one or both of the structural skins. The gasket 24 may be sandwiched between the peripheral edges of the skins 18, 20 to close and seal the carriage wall core 17. The carriage wall skins 18, 20 may be configured to cooperate in the carriage and distribution of missile carriage loads. The carriage wall structural skins 18, 20 may be machined from aluminum slabs or may, in other embodiments, be formed by any suitable means from any suitable material.
As shown in FIGS. 7 and 8, the rails 12 may be distributed between and carried by the front and back structural skins 18, 20 of the carriage wall 16. Four of the eight rails 12 may be carried by the front skin 18 of the carriage wall 16 and the remaining four rails 12 carried by the back skin 20 of the carriage wall 16. The launch rails 12 of the plurality of launch rails 12 may be spaced laterally and oriented generally parallel to one another on the front and back skins 18, 20 of the carriage wall 16.
To provide structural stiffness in the carriage wall 16, the front and back structural skins 18, 20 may be machined to leave hard points 28 that project integrally inward from inner surfaces of the skins 18, 20 as shown in FIG. 8. The hard points 28 may be configured to engage one another when the skins 18, 20 are closed together. Alternatively, or in addition to the hard points 28, the carriage wall 16 may comprise a filler 29 disposed between the front and back structural skins 18, 20 to add stiffness. The filler 29 may comprise, for example, aluminum honeycomb or a heat-resistant materials comprising, for example, Nomex®.
As shown in FIG. 8, the module 10 may include sprinkler nozzles 30 carried by and distributed between the front and back structural skins 18, 20 of the carriage wall 16. Sixteen such nozzles 30 are distributed between the front and back structural skins 18, 20 in the present embodiment, but in other embodiments any suitable number of sprinkler nozzles 30 may be used. Each sprinkler nozzle 30 may be connected to sprinkler piping 32 that may be connected to a fluid source 33. The sprinkler piping 32 may be configured to provide a fluid pathway through the carriage wall core 17 and carriage wall structural skins 18, 20 for a fluid, such as a fire suppressant fluid, to be delivered to and dispensed through the sprinkler nozzles 30. The sprinkler nozzles 30 may be configured to dispense fluid in a direction and manner that suppresses missile exhaust flame. The sprinkler nozzles 30 may be selected, configured, and/or positioned to perform in a manner that meets safety requirements for whatever type of missiles 14 are to be carried by and launched from the module 10. For example, the nozzles 30 may be configured to spray fluid in a pattern that will wet-down and cool critical components such as warheads and/or pressure vessel sections of missiles 14 carried by the rails 12. The nozzles 30 may also or alternatively be located relatively high on the carriage wall 16 to allow gravity to help direct the spray pattern to cover a vast majority of desired areas and components.
As shown in FIG. 8 the sprinkler piping 32 may include an external portion 34 extending from the fluid source 33 to the carriage wall 16, and an internal portion 36 extending through the carriage wall core 17. The internal portion 36 may comprise machined-in piping walls that integrally extend from at least one of the inner surfaces of the structural skins 18, 20 and compress rubber seal strips 38 against an opposing inner surface or piping wall to define a fluid channel between the structural skins 18, 20.
The sprinkler piping 32 may further comprise a penetration interface (not shown) disposed between peripheral edges of the carriage wall structural skins 18, 20. The penetration interface may be configured to provide fluid communication between the external and internal sprinkler piping portions 34, 36 while maintaining a seal between the peripheral edges of the carriage wall structural skins 18, 20. The penetration interface may comprise any suitable interface known in the art such as, for example, a fluid tube cable that extends between the carriage wall structural skins 18, 20 and that is sealed by a gland nut. Alternatively, the penetration interface may comprise a bulkhead interface comprising a permanent or quick disconnect connector mounted and sealed to one or both carriage wall structural skins 18, 20.
The module 10 may include desiccant holder structures 42 configured to carry long-term storage desiccant within the carriage wall core 17 to maintain a dry environment within the carriage wall core 17. As shown in FIG. 8, the desiccant holder structures 42 may be machined into the inner surfaces of the carriage wall skins 18, 20 to support the desiccant material in advantageous locations within the core 17.
The module 10 may include environmental sensors 44 disposed in the carriage wall core 17 as shown in FIG. 8. The environmental sensors 44 may be configured to monitor conditions within the core 17 such as temperature, humidity, shock, vibration and the like, to monitor maintenance and safety requirements.
FIG. 8 shows that the carriage wall 16 may include an integral cableway 46 comprising cableway walls 48 that integrally extend from the inner surfaces of at least one of the structural skins 18, 20 and compress rubber seal strips 38 against an opposing inner surface or cableway wall to define a cable channel between the structural skins 18, 20. The cableway walls 48 may run through the carriage wall core 17 and cooperate to form a channel configured to receive cabling (not shown), such as missile umbilical cabling, connecting the missiles 14 mounted on the rails 12 to a launcher electronics assembly such as an M299 Launcher Electronics Assembly (LEA) from an M299 missile launch system. The missile umbilical cabling may carry signals related to munitions control and monitoring. The integral cableway 46 may also or alternatively receive rail cabling connecting the rails 12 to the launcher electronics assembly for controlling and/or powering the environmental sensors 44, and/or other systems such as access/intrusion sensors, and/or rail-related electromechanical devices.
As shown in FIGS. 3-9, the module 10 may include a pair of spaced-apart generally parallel end walls 50 carrying the common carriage wall 16 between them. As shown in FIG. 3, the end walls 50 may be configured to be carried by mounting interfaces of a module supporting structure 52, e.g., a ship-board structure configured to carry a missile carriage and launch module 10. Such a ship-board structure 52 may include a set of C channels or I beams that may carry attachment point hardware, e.g., a Base Ship Structure (BSS) or slightly modified version thereof
As shown in FIGS. 5-8, the module 10 may include a plenum 54 carried by and between the end walls 50. The plenum 54 may be configured and positioned to receive and re-direct exhaust gases from missiles 14 being launched from the module 10. The plenum 54 may direct the exhaust gases to a discharge chute 56 configured to direct gases up through an uptake hatch 58 level with a deck of a ship in which the module 10 is mounted as best shown in FIG. 6. The plenum 54 may include siliconized ablatives on interior surface areas of the plenum 54 where missile exhaust impinges, and may include other types of ablatives on other interior surface areas.
As shown in FIGS. 3-6, the module 10 may include a module lid 60 (or deck interface) carried by, and connected to and sealed by any suitable means to a top edge of the carriage wall 16. The module lid 60 may be connected and sealed by any suitable means to top edges of the end walls 50. The module lid 60 may be mounted flush with the deck as shown in FIG. 3, and may include a rigid rectangular opening grid which may support flexible membranes configured to tear open when missiles 14 are launched through them. The carriage wall 16, module lid 60, plenum 54, and end walls 50 may be interconnected in such a way as to provide structural stiffness between these elements and to transfer loads from the carriage wall 16 and plenum to mounting interfaces of a structure, e.g., a ship-board structure, which is to carry the module 10.
As best shown in FIGS. 7 and 8, the end walls 50 may be connected by any suitable means at or adjacent respective top ends to the module lid 60. At or adjacent respective lower ends of the end walls 50, the end walls 50 may be connected to the plenum 54. The end walls 50 may be connected along inner vertical median regions to respective side edges of the carriage wall 16. The end walls 50 may thus support the plenum 54 in a position to receive and re-direct exhaust gases from missiles 14 being launched from the module 10, and to provide structural rigidity between the carriage wall 16, module lid, and the mounting interfaces of a structure carrying the module 10.
The module 10 may include front and back generally rectangular shell covers 62 removably disposed across and closing respective front and back module openings. The front module opening may be defined by front edges of the module lid 60, end walls 50, and plenum 54. The back opening may be defined by back edges of the module lid 60, end walls 50, and plenum 54. The shell covers 62 may be removable to provide access to the rails 12 and/or missiles 14 carried by the rails 12.
As best shown in FIGS. 5 and 6, each shell cover 62 may comprise a main cover panel 64 shaped to be removably disposed across and close a module opening 65, and 3 missile separator panels 66 integrally extending from the main cover panel 64. The missile separator panels 66 may be spaced apart and configured to engage the carriage wall 16 and divide the spaces between the carriage wall 16 and the shell covers 62 into cells for individually housing missiles 14 carried by the rails 12 to protect such missiles 14 from each others' exhaust during launch. While the Figures show three missile separator panels 66 being used to separate four missiles 14 per shell cover 62, other embodiments may employ shell covers 62 configured with either more or fewer separator panels 66 corresponding to the various numbers of rails 12, missiles 14, etc. included in that embodiment.
The separator panels 66 may be sealed against outer surfaces of the carriage wall structural skins by, for example, linear wedge seals 68 configured to receive and engage mating linear hooks 76, as shown in FIGS. 9-14. The linear wedge seals 68 may comprise a sliding clamp 72, a brace 70, and mounting bolts 74 configured to attach the sliding clamp 72 to the brace 70. The sliding clamp 72 may include diagonal slots configured to receive the mounting bolts 74, such that the sliding clamp 72 may slide around the mounting bolts 74 along a path that allows it to approach and withdraw from the brace 70 as shown in FIGS. 11 and 12. The linear wedge seal 68 may be configured to receive the mating linear hook 76 between the brace 70 and the sliding clamp 72, and may be configured to seal the linear hook 76 between the brace 70 and the sliding clamp 72 by sliding the sliding clamp 70 along the path allowed by the diagonal slots 76 until it establishes a compression seal with the brace 70 and the linear hook 76 as shown in FIG. 14. As shown in FIG. 9, one of the linear hook 76 or linear wedge seal 68 may be carried by the carriage wall 16, the end walls 50, and/or by any of the main cover or separator panels 64, 66, such that each linear hook 76 may engage a linear wedge seal 68 when the cover panel 64 is installed. In the drawings the wedge seals 68 and linear hooks 76 are configured such that each cover panel 64 may be installed by sliding the cover panel's linear hooks 76 endwise into wedge seals 68 installed on the carriage wall 16 and end walls 60. In other words, the cover panels 64 may be installed vertically through the top of the module 10. However, in other embodiments, the wedge seals 68 may be oriented to allow the shell covers 62 to be installed from the sides of the module 10, into each module opening 65, or from any other unobstructed direction.
A typical configuration of an LCSVLS may, for example, include a Surface-to-Surface Mission Module (SSMM) comprising two Surface-to-Surface Missile Systems (SSMS). Each SSMS may include three missile launch modules 10, and a Launcher Management Assembly (LMA), e.g., an M299 LMA. Each LMA may be configured to control the three launch modules 10 in its SSMS. Each module 10 may be individually removable from its SSMS, allowing a module 10 with expended missiles 14 to be removed and reloaded with missiles 14 or replaced with a pre-loaded module 10.
A multiple missile carriage and launch guidance module as described above provides a space and weight-efficient platform capable of safely storing, monitoring, and launching missiles. This description, rather than describing limitations of an invention, only illustrates an embodiment of the invention recited in the claims. The language of this description is therefore exclusively descriptive and is non-limiting. Obviously, it's possible to modify this invention from what the description teaches. Within the scope of the claims, one may practice the invention other than as described above.
