Description

FIELD OF THE INVENTION

The present invention relates to missilery in general, and, more particularly, to missile launchers.

BACKGROUND OF THE INVENTION

A missile is propelled by fuel and a chemical-propulsion engine. A chemical-propulsion engine propels a missile by the reaction that results from the rearward discharge of gases that are liberated when the fuel is burned. For the purposes of this specification, a “missile” is defined as a projectile whose trajectory is not necessarily ballistic and can be altered during flight (as by a target-seeking radar device and control elements).
Multi-cell missile launchers have been developed for several types of missiles. FIG. 1 depicts two such multi-cell missile launchers mounted to the deck of warship 100 as is known in the prior art. In some prior art arrangements, the multi-cell missile launchers are mounted below the deck. Each launcher is capable of locating, holding, and launching a plurality of a single type of missile canister. The type(s) of launcher is chosen based on the desired capability of the weapons platform, such as warship 100.
FIG. 2 depicts a perspective-view of a Lockheed-Martin MK 41 multi-cell missile launcher, which is an example of a multi-cell missile launcher known in the prior art. Each cell of the multi-cell missile launcher is the same (i.e., only one type of missile is launched from the launcher). A characteristic of modern warfare is the need to derive multi-functional capability from weapons platforms used in battle. A warship, for example, might need to launch surface-to-surface missiles during one phase of a battle, and surface-to-air missiles during a different phase of the same battle. Currently, multi-functionality is derived at the level of the systems platform, such as warship 100, by providing multiple missile launching systems wherein each missile launching system has different functionality. In order to attain multi-functional capability for the weapons platform, multiple launchers are required, which leads to added infrastructure, space requirement, and expense for the weapons platform.
The multi-cell missile launcher depicted in FIG. 2 comprises a 2×4 array of MK-41 launch cells, each of which contains a missile of the same type. Each cell is controlled by a MK-41 controller, which contains data and information that is specific to the type of guided missile contained in the launch cells.
In the prior art, missile canisters have been adapted to hold missiles that are smaller than the missiles for which these missile canisters have been designed. However, this leads to wasted space and reduced firepower for the launch system. In addition, the size of the missile canister limits the size of the missile that can be used, which limits the flexibility of existing missile launchers.
Therefore, the need exists for a missile launcher that avoids or mitigates some or all of these problems.

SUMMARY OF THE INVENTION

The present invention provides a missile launch system that can be reconfigured to launch missiles of various types and sizes. In particular, the illustrative embodiment of the present invention uses variable-sized receptacles for locating and holding different types of missile canisters. In addition, the illustrative embodiment uses a controller that contains a data set of information for each type of missile for which the reconfigurable launcher can be configured. This mitigates some of the problems associated with launching multiple missile types in the prior art.
The illustrative embodiment comprises: a missile canister, a missile contained in the missile canister, a reconfigurable receptacle for locating and holding any one of a plurality of missile canister types, an reconfigurable exhaust system for venting fumes from missile canisters in any allowed launcher configuration, and a controller for controlling a plurality of missile types.

DETAILED DESCRIPTION

FIG. 3 depicts a representational diagram of a naval launch system in accordance with the illustrative embodiment. Although reconfigurable multi-cell missile launcher 302 (hereinafter referred to as “reconfigurable launcher” 302) is mounted on the deck of warship 100, it will be clear to those skilled in the art, after reading this disclosure, how to make and use alternative embodiments of the present invention in which reconfigurable launcher 302 is mounted below the deck of warship 100, is terrestrially-based, or is mounted on another type of vehicle (e.g., a truck, a railroad car, a submarine, a space vehicle, a satellite, etc.)
FIG. 4 depicts a block diagram of reconfigurable launcher 302 in accordance with the illustrative embodiment. Although only a one-dimensional array of four launch cells is shown in FIG. 4, it will be clear to those skilled in the art, after reading this disclosure, how to make and use alternative embodiments of the present invention in which launch system 302 comprises a single reconfigurable launch cell, a one-dimensional array of any number of reconfigurable launch cells, or a two-dimensional array of any number of reconfigurable launch cells.
Reconfigurable launcher 302 comprises Type-A launch cell 404 ₁, two Type- B launch cells 404 ₂and 404 ₄, Type-C launch cell 404 ₃, exhaust system 406, cable 410, and multi-missile controller 408. The missile types, A, B, and C represent three different nonspecific missile types, each having a different canister size.
Exhaust system 406 is connected to all launch cells 404 ₁through 404 ₄via exhaust outlets such that exhaust system 406 vents exhaust fumes generated during the launch of a missile in one or all of launch cells 404 ₁through 404 ₄. Exhaust system 406 is described in detail below and with respect to FIGS. 7 and 8.
Multi-missile controller 408 contains multiple data sets, wherein each data set contains the data and information specific to the control and launch of each missile type for which reconfigurable launcher 302 is configured. Multi-missile controller 408 is connected to each launch cell 404 ₁through 404 ₄via cable 410, so as to provide bi-directional communications between multi-missile controller 408 and each launch cell. Multi-missile controller 408 is described in detail below and with respect to FIG. 6.
FIG. 5 depicts a block diagram of launch cell 404 _i, wherein i is a positive integer in the set {1, . . . , 4}, in accordance with the illustrative embodiment. Launch cell 404 _icomprises receptacle 512 _i, missile canister 514 _i, missile 516 _i, and exhaust outlet 518 _i.
Receptacle 512 _ilocates and secures missile canister 514 _i, which includes missile 516 _i. Exhaust outlet 518 _iprovides a path through which the exhaust fumes generated by missile 516 _iduring launch can escape from launch cell 404 _i. The size of receptacle 512 _idetermines the type of missile canister 514 _i. Different types of missiles are contained in missile canisters of different sizes. Therefore, in order to enable reconfigurable launcher 302 to accommodate different missile types, the size of receptacle 512 _iis reconfigurable, as well as the position of exhaust outlet 518 _i. The reconfigurability of receptacle 512 _iand exhaust outlet 518 _iis described in detail below and with respect to FIG. 7.
FIG. 6 depicts a block diagram of multi-missile controller 408 in accordance with the illustrative embodiment. Multi-missile controller 408 comprises processor 620 and memory 622. Memory 622 comprises N data sets 624 _i, wherein i is a positive integer in the set {1, . . . , N}. Each data set 624 _iincludes data and information specific to the control and launch of one of the N missile types for which reconfigurable launcher 302 can be configured.
FIG. 7 depicts a cross-sectional view of launch cell 404 _iin accordance with the illustrative embodiment. Launch cell 404 _icomprises missile canister 514 _i, exhaust outlet 518 _i, platform 720, movable supports 722 _iand 722 _i+1, missile 516 _i, missile canister connector 724 _i, and missile canister-to-missile umbilical 726 _i.
Platform 720 and movable supports 722 _iand 722 _i+1locate and support missile canister 514. The position of movable supports 722 _iand 722 _i+1can be changed such that the spacing between them accepts a missile canister different than missile canister 514 _i, and therefore a missile different than missile 516 _i. Movement of movable supports 722 _iand 722 _i+1can be accomplished using hydraulics, electric motors, or manual means. It will be clear to those skilled in the art how to position movable supports 722 _iand 722 _i+1.
The total size of reconfigurable launcher 302 is fixed and each of movable supports 722 may be shared between two adjacent launch cells 404 _iand 404 _i±1. Therefore, as the size of launch cell 404 _iis changed, the size of adjacent launch cell 404 _i−1or 404 _i+1is changed as well. For example, as movable support 722 _iis moved toward the left to enable location of a larger missile canister in receptacle 512 _i, the opening between movable support 722 _iand 722 _i−1(not shown) is made smaller. Thus, the type of missile canister that can be located by receptacle 512 _i−1is changed. In some configurations, reconfigurable launcher 302 will have less than four launch cells, while in other configurations reconfigurable launcher 302 will have more than four launch cells.
Missile canister 514 _iincludes a fly-through cover on one end, and a missile canister back plate on the other end. The missile canister back plate either opens or bursts upon ignition of missile 516 _ito provide access to exhaust outlet 518 _ifor exhaust fumes from missile 516 _i. Exhaust outlet 518 _ivents exhaust fumes into exhaust plenum 728, where they combine with the exhaust fumes from other launch cells. It will be clear to those skilled in the art how to make and use a missile canister back plate that provides access to exhaust outlet 518 _iupon ignition of missile 516 _i. The position of exhaust outlet 518 _iis reconfigurable to accommodate any of the missile types for which reconfigurable launcher 302 is configured.
Missile 514 _icommunicates with multi-missile controller 408 via cable 410. Cable 410 is connected to missile 514 _ithrough cable connector 726 _i, missile canister connector 724 _i, and missile canister-to-missile umbilical 726 _i. In the illustrative embodiment, cable connector 726 is a universal connector that can mate to any of the missile canister connectors associated with each missile canister type for which reconfigurable launcher 302 is suitable. In some embodiments, cable 410 includes a plurality of cable connectors, one for each type of missile canister type for which reconfigurable launcher 302 is suitable.
FIG. 8 depicts a cross-sectional view of exhaust system 406 in accordance with the illustrative embodiment. Exhaust system 406 comprises exhaust plenum 728, exhaust outlets 518 _i, wherein i is a positive integer in the set {1, . . . , 5}, and exhaust uptake 830. Each launch cell 404 ₁through 404 ₄includes an exhaust outlet 518 ₁through 518 ₄, such that the exhaust fumes generated during a missile launch in that cell are directed into exhaust plenum 728. An additional exhaust outlet 518 ₅provides access to exhaust uptake 830 for the exhaust fumes in exhaust plenum 728. Exhaust uptake 830 provides egress for the exhaust fumes into the atmosphere that surrounds reconfigurable launcher 302.
In some embodiments of the present invention, exhaust system 406 includes a plurality of exhaust uptakes 830. In some embodiments of the present invention, exhaust uptake 830 is located in the interior of reconfigurable launcher 830, i.e. between two launch cells such as launch cells 404 ₂and 404 ₃. In some embodiments of the present invention, platform 720 comprises through-holes that allow exhaust fumes to vent directly through platform 720 and into and out of exhaust plenum 728, obviating discrete exhaust outlets 518 ₁through 518 ₅.
