An elongated submunition delivery device 100 may include a dispense fuze module 13, a master electronics module 12, a base plug module 10, and a submunition module comprising submunition banks 11 separated by bulkheads 14. Each of the submunition banks 11 may include elongated submunitions 15 of similar sizes.
The submunition delivery device 100 also may be configured to include a single instance of an electronic device 25 only in the master electronic module 12. Therefore there may be no need to have other instances of the electronic device 25 according to an embodiment. The specific electronic device may include an environmental sensor, or a master safe and arm device.
In an embodiment, the aero-elements 19 are mounted around the periphery of the submunitions 15, and the aero-elements 19 may have a retracted position and an extended position. For example,
In an embodiment, the aero-elements 19 may include one or more of deployment stages illustrated in
In an embodiment, each of the elongated openings 21 may include strips 20. The strips 20 may be configured in broached t-slots or flexible electronic cabling. The strips 20 may be made from a brass material. In an exemplary embodiment, the number of the strips 20 in the broached t-slots of each of the elongated openings 21 is equal to the number of the contact pins 23 of each of the submunitions 15. In an embodiment, pins 23 and strips 20 electronically connect the electronic submunition fuzes 16 to the master electronic module 12 or to a master safe and arm device in the master electronic module 12. In an embodiment, the strips 20 include brass material.
According to an embodiment, electronic cables 28a and 35a may be configured in circular shapes such that one submunition may be located within the perimeter of the electronic cable 35a and multiple submunitions may be located outside the perimeter of the electronic cable 35a and inside the perimeter of the electronic cable 28a. In the exemplary embodiment shown in
In an embodiment, electronic cables 28a, 28b, 31a, 31b, 35a, and 35b may be configured to connect multiple layers of the submunitions 15 in the nesting device 24. In an embodiment electrical cable 32 and electrical cable 33 connect electrical cable 28a of a first stack 24a of submunitions 15 to the electronic cable 28b of a second stack 24b of submunitions 15. Electronic cable 32 may connect to connector 29a and connector 29b. Cable 33 may connect to connectors 30a and 30b. Electronic cable 37 may connect electrical cable 35a of a first stack 24a of submunitions 15 to the electronic cable 35b of a second stack 24b of submunitions 15. In an embodiment, the first stack of electronic cables 28a and 35a may connect to the second stack of electronic cables 28b and 35b by electronic cables 32, 33, and 37.

In an embodiment, electronic cables connect electronic submunition fuzes 16 to the master electronic module 12 or to the master safe and arm device in the master electronic module 12. In an embodiment, the electronic cables may be flexible electronic cables.
A distributed fuze architecture (DFA) may arm all submunitions before the dispense action. The DFA may control the arming scenario more precisely. The DFA may limit the detrimental effect of submunition on submunition collisions. The DFA may increase reliability and allow the round to meet 1% unexploded ordnance (UXO) requirements. The DFA also may have the potential to reduce the cost of the submunition delivery device 100. The DFA may require a single instance of certain electronic devices, such as environmental sensors, in the master electronics module 12. The DFA may replace the traditional mechanical stab firing pin detonator (M55) with an electronic detonator that is sensitive to off angle of attack.
Some components of the embodiments herein can include a computer program product configured to include a pre-configured set of instructions stored in non-volatile memory, which when performed, can result in actions as stated in conjunction with the methods described above. In an embodiment, the computer program may provide for programming or configuring a processor, or an FPGA, or any other programmable hardware in the master electronic unit or in the electronic submunition fuze 16. The computer program may provide for electronically controlling arming of the submunitions 15 in a timely manner in an embodiment. The computer program may also provide for controlling the timing of the aero-element deployment expulse sequence. Control functions provided by the computer program may be remotely managed according to an embodiment.
In an example, the pre-configured set of instructions can be stored on a tangible non-transitory computer readable medium or a program storage device. In an example, the tangible non-transitory computer readable medium may be configured to include the set of instructions, which when performed by a device, may cause the device to perform acts similar to the ones described here.
The embodiments herein may also include tangible and/or non-transitory computer-readable storage media for carrying or having computer executable instructions or data structures stored thereon. Such non-transitory computer readable storage media can be any available media that can be accessed by a special purpose computer, including the functional design of any special purpose processor, module, or circuit as discussed above. By way of example, and not limitation, such non-transitory computer-readable media can include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code means in the form of computer executable instructions, data structures, or processor chip design. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or combination thereof) to a computer, the computer properly views the connection as a computer-readable medium. Thus, any such connection is properly termed a computer-readable medium. Combinations of the above should also be included within the scope of the computer-readable media.
Computer-executable instructions include, for example, instructions and data which cause a special purpose computer or special purpose processing device to perform a certain function or group of functions. Computer-executable instructions also include program modules that are executed by computers in stand-alone or network environments. Generally, program modules include routines, programs, components, data structures, objects, and the functions inherent in the design of special-purpose processors, etc. that perform particular tasks or implement particular abstract data types. Computer executable instructions, associated data structures, and program modules represent examples of the program code means for executing steps of the methods disclosed herein. The particular sequence of such executable instructions or associated data structures represents examples of corresponding acts for implementing the functions described in such steps.
The techniques provided by the embodiments herein may be implemented on an integrated circuit chip (not shown). The chip design is created in a graphical computer programming language, and stored in a computer storage medium (such as a disk, tape, physical hard drive, or virtual hard drive such as in a storage access network). If the designer does not fabricate chips or the photolithographic masks used to fabricate chips, the designer transmits the resulting design by physical means (e.g., by providing a copy of the storage medium storing the design) or electronically (e.g., through the Internet) to such entities, directly or indirectly. The stored design is then converted into the appropriate format (e.g., GDSII) for the fabrication of photolithographic masks, which typically include multiple copies of the chip design in question that are to be formed on a wafer. The photolithographic masks are utilized to define areas of the wafer (and/or the layers thereon) to be etched or otherwise processed.
The resulting integrated circuit chips can be distributed by the fabricator in raw wafer form (that is, as a single wafer that has multiple unpackaged chips), as a bare die, or in a packaged form. In the latter case, the chip is mounted in a single chip package (such as a plastic carrier, with leads that are affixed to a motherboard or other higher level carrier) or in a multichip package (such as a ceramic carrier that has either or both surface interconnections or buried interconnections). In any case, the chip is then integrated with other chips, discrete circuit elements, and/or other signal processing devices as part of either (a) an intermediate product, such as a motherboard, or (b) an end product. The end product can be any product that includes integrated circuit chips, ranging from toys and other low-end applications to advanced computer products having a display, a keyboard or other input device, and a central processor, and may be configured, for example, as a kiosk.
The embodiments herein can include both hardware and software elements. The embodiments that are implemented in software include but are not limited to, firmware, resident software, microcode, etc. Furthermore, the embodiments herein can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can comprise, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk—read only memory (CD-ROM), compact disk—read/write (CD-R/W) and DVD.
A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/output (I/O) devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers. Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
