The invention relates generally to missile launcher systems. In particular, the invention relates to missile launcher systems used to deploy missiles on a naval vessel, for example.
Naval vessels are often outfitted with missile launching systems for launching a missile from the vessel. Conventional launchers include the armored box launcher and a larger capacity vertical launching system. Such conventional launcher systems, however, cannot be reloaded at sea. Typically, vessels carrying such missile launchers must return to port to be reloaded. Moreover, these missile launchers are designed for large vessels and may not be suitable for deployment on smaller platforms, such as a coastal patrol craft.
Additionally, many conventional missile launchers are not designed for the harsh conditions of salt and water present while at sea. Hence, there is a need for a missile launcher that can withstand marine environments, that can permit reloading while at sea, and that can be simply and safely integrated into a variety of naval vessels, land vehicles, fixed locations, and other such locations, as needed.
Conventional missile launchers yield disadvantages addressed by various exemplary embodiments of the present invention. Various exemplary embodiments provide a missile launcher having a pedestal operable to mount to a surface; and launcher box or container attached to the pedestal, the launcher box creating an environmental seal for missiles and missile canisters disposed therein. In additional embodiments, the missile launcher further includes wire rope isolators installed in a shear configuration, securing the launcher box to the pedestal; a base plate of the launcher box having at least one canister saddle attached thereto; and a plurality of upper clamps; fore and aft plates; a seal ring; an O-ring; a removable top cover and a forward hatch.
The canister saddles have an indent for receiving the missile canisters. The upper clamps each has independently and removably attached to the canister saddle to secure a single missile canister thereunder. The aft plate is disposed on an aft end of the launcher box and has a plurality of aft end plate holes therethrough. The plurality of aft end plate holes align with the missile canisters. The fore plate is disposed on a forward end of the launcher box and having a plurality of forward end plate holes therethrough, the plurality of forward end plate holes aligning with the missile canisters.
The seal ring is disposed about forward and aft ends of each missile canister, aligning with the plurality of aft end plate holes and corresponding forward end plate holes. The O-ring is disposed between the seal ring and either the forward or aft plate. The removable top cover on the launcher box. The forward hatch is disposed on a forward end of the launcher box, hingeably attached to the launcher box to cover and uncover the forward plate. The aft hatch is disposed on an aft end of the launcher box, the aft hatch hingeably attached to the launcher box to cover and uncover the aft plate.
These and various other features and aspects of various exemplary embodiments will be readily understood with reference to the following detailed description taken in conjunction with the accompanying drawings, in which like or similar numbers are used throughout, and in which:
In the following detailed description of exemplary embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized, and logical, mechanical, and other changes may be made without departing from the spirit or scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
Various exemplary embodiments provide a missile launcher that affords simple and safe integration onto a naval vessel, for example. The missile launcher includes a box launcher intended to house and launch the missiles and a pedestal to support and orient the box launcher. The box launcher provides protection from the natural environment as well as protection from other threats to the system. The box launcher enables missiles not normally designed for a harsh marine environment to be deployed and operated therein. The missile launcher also enables the ability to load missiles while at sea. The missile launcher can be integrated into naval vessels, land vehicles, fixed locations and other installations, as needed.
While shipboard missile launchers are relatively common, the missile launcher, according to an inventive embodiment, adapts a man-portable missile system, such as the AGM-176 Griffin precision kinetic effects tube-launched munition, having comparatively minimal environmental protection for integration into a box launcher to install in a marine environment and deployed long-term (e.g., months at sea). In addition, the launcher box can be a universal design, so as to be installed in numerous locations, at numerous azimuth or elevation angles, and on different platforms.
Also, many missile systems, such as the Griffin, are not equipped for long-term exposure to a marine environment. The exemplary missile launcher includes a pedestal to protect missiles from the damaging effects of shipboard vibration, shock from wave slap and sea keeping conditions, as well as other wartime threats, such as nearby mine detonation and small arms fire.
As shown in
An upper clamp 24 can be installed over each of the indents formed along the canister saddle 18. The upper clamp 24 can be removably secured to the canister saddle 18 by various mechanisms. For example, a support post 26 may extend from the canister saddle 18 and pass through the upper clamp 24, permitting a nut 28, or the like, to secure the upper clamp 24 on the support post 26. Of course, other attachment means can be contemplated within the scope of the inventive concepts herein, provided that the upper clamp 24 is removeable from the canister saddle 18 to permit loading, unloading or reloading of the canister 20 into the launcher box 12. Separate upper clamps 24 can be used for each of the canisters 20, facilitating installation or removal of one canister at a time, ensuring that an operator need not concurrently contend with multiple loose missiles.
Side walls 30 can extend from opposite sides of the bottom plate 16 of the launcher box 12. A forward plate 32 can extend from a forward end of the bottom plate 16 and an aft plate 34 can extend from an aft end of the bottom plate 16. These side walls 30, forward plate 32, and aft plate 34 can be permanently affixed and sealed to the bottom plate 16 in order to inhibit intrusion into the launcher box 12.
A top cover 36 (shown as a plate similar to the bottom plate 16) can removably attach to the side walls 30, forward plate 32, and aft plate 34. The top cover 36 can include one or more handles 38 to help removing and attaching the top cover 36. The top cover 36 can attach to the launcher box 12 by various techniques, such as with socket head cap screws, eye nuts on swing bolts, or the like. A seal (not shown) can be disposed between the top cover 36 and the periphery of the launcher box 12 to prevent water or other substance intrusion into box interior.
For each canister 20, a seal ring 40 can be disposed on each end thereof. The canister 20 is disposed onto the canister saddles 18. Then a seal ring 40 at each end can be moved toward the forward plate 32 to the left and the aft plate 34 to the right and attached thereto with a removable attachment mechanism, such as a set of screws 42, for example, as shown in
When a canister 20 is not installed in one of the locations (indents) along the canister saddle 18, a blanking plate 46 can be disposed over the appropriate opening in the forward plate 32 and the aft plate 34. The blanking plate 46 can mount to either the forward plate 32 or else the aft plate 34 by the screws 42 and with the O-ring 44 disposed therebetween.
A forward hatch 48 can hingeably attach to cover and uncover the forward plate 32. Similarly, an aft hatch 50 can hingeably attach to cover and uncover the aft plate 34. A seal 52 may be disposed about an inner perimeter of the forward hatch 48 and the aft hatch 50 to help seal the forward hatch 48 to the forward plate 32, and the aft hatch 50 to the aft plate 34.
A hatch restraint 54 can secure the forward hatch 48 and the aft hatch 50 to remain in an open configuration. An electrical switch associated with the restraint 54 can produce an indicator signal (for an operator display monitor) that the forward hatch 48 and the aft hatch 50 are open or closed, depending on deployment of the restraint 54 as secured or not. This electrical signal may be supplied to a launching system computer (not shown) to prevent launch of a missile with either or both of the hatches 48 and 50 in a closed position.
In some embodiments, a protective ring 56 can be attached to the outside surface of the aft plate 34. A gasket 58 can be disposed between the protective ring 56 and the aft plate 34. The protective ring 56 can help protect the aft plate 34 from hot missile exhaust when a missile is launched. While the drawings show the canister saddles 18 disposed at particular locations on the bottom plate 16, depending on the canister to be mounted in the launcher box 12, the number of and location of the canister saddles 18 can vary. In some embodiments, the canister saddles 18 can be integrated with the seal rings 40, thereby combining the environmental sealing with the mechanical restraint at the same location.
