연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A distributed ordnance system comprises a plurality of ordnance controllers and a plurality of firing units. Each ordnance controller of the plurality of ordnance controllers may be operably coupled with at least one firing unit of the plurality of firing units. Each ordnance controller may be configured to provide power signals to the at least one firing unit coupled therewith, and communicate with the at least one firing unit for initiation of an ordnance event. A multiple-stage ordnance system may comprise a first stage and a second stage that each include an ordnance controller configured to control operation of an ordnance event, and at least one firing unit to initiate the ordnance event. Related methods for constructing a multiple-stage ordnance control system and controlling initiation of an energetic material are also disclosed.

1. A distributed ordnance system, comprising: a plurality of ordnance controllers; and a plurality of firing units, each firing unit configured to receive a plurality of electronic safe and arm (ESA) power signals from an associated ordnance controller for both arming and charging the firing unit prior to discharge, wherein each ordnance controller of the plurality of ordnance controllers: is operably coupled with at least one firing unit of the plurality of firing units; is configured to provide the plurality of ESA power signals to the at least one firing unit coupled therewith; is configured to communicate with the at least one firing unit for initiation of an ordnance event; and includes a safety plug configured to manually disconnect the plurality of ESA power signals for the associated ordnance controller. 2. The distributed ordnance system of claim 1, wherein each ordnance controller is operably coupled with the at least one firing unit coupled therewith through a digital communication bus. 3. The distributed ordnance system of claim 2, wherein the digital communication bus has a communication bus protocol selected from the group consisting of a controller area network (CAN), Ethernet, RS422, RS232, and RS485. 4. The distributed ordnance system of claim 2, wherein at least one ordnance controller of the plurality of ordnance controllers is operably coupled to at least one additional firing unit of the plurality of firing units. 5. The distributed ordnance system of claim 2, wherein the plurality of ESA power signals and the digital communication bus are provided within common cabling. 6. The distributed ordnance system of claim 2, wherein the plurality of ordnance controllers are operably coupled to each other with a common bus from a main controller. 7. The distributed ordnance system of claim 6, wherein the common bus includes the plurality of ESA signals provided from the main controller to the plurality of ordnance controllers. 8. The distributed ordnance system of claim 6, wherein the common bus includes the digital communication bus provided from the main controller to the plurality of ordnance controllers. 9. The distributed ordnance system of claim 1, wherein the safety plug is configured to manually disconnect the plurality of ESA signals from downstream ordnance controllers of the plurality of ordnance controllers that are serially coupled to receive the plurality of ESA power signals from an upstream ordnance controller. 10. The distributed ordnance system of claim 1, wherein the plurality of firing units comprise a plurality of high voltage firing units. 11. A multiple-stage ordnance system, comprising: a first stage, comprising: a first ordnance controller configured to control operation of a first ordnance event within the first stage; at least one first firing unit operably coupled with the first ordnance controller to initiate the first ordnance event; and a first safety plug configured to receive at least one electronic safe and arm (ESA) power signal and selectively provide the ESA power signal to the at least one first firing unit according to a state of a manual disconnect for the first safety plug; and a second stage, comprising: a second ordnance controller configured to control operation of a second ordnance event within the second stage; at least one second firing unit operably coupled with the second ordnance controller to initiate the second ordnance event; and a second safety plug configured to receive the at least one ESA power signal from the first stage, and selectively provide the ESA power signal to the at least one first firing unit according to a state of a manual disconnect for the second safety plug. 12. The multiple-stage ordnance system of claim 11, wherein each of the at least one first firing unit and the at least one second firing unit is individually addressable by the respective one of the first ordnance controller and the second ordnance controller. 13. The multiple-stage ordnance system of claim 11, wherein the first ordnance controller is further configured to manage flight controls for the first stage of a multiple-stage flight vehicle. 14. The multiple-stage ordnance system of claim 11, further comprising an avionics control system operably coupled with the first ordnance controller and the second ordnance controller over a common bus architecture. 15. The multiple-stage ordnance system of claim 14, further comprising a power controller and conditioner located proximate the avionics control system, the power controller and conditioner configured to generate the at least one ESA power signal to each of the first ordnance controller and the second ordnance controller. 16. The multiple-stage ordnance system of claim 15, wherein the first safety plug is further configured to selectively provide the at least one ESA power signal to the second safety plug of the second ordnance controller according to the state of the manual disconnect for the first safety plug. 17. A method of constructing a multiple-stage ordnance control system, the method comprising: coupling a first ordnance controller with at least one first firing unit of a first stage having a first safety plug; testing components of the first stage with the first safety plug manually disconnected; coupling the first ordnance controller and the second ordnance controller; coupling a second ordnance controller with at least one second firing unit of a second stage having a second safety plug; and testing components of the second stage with the second safety plug manually disconnected and the first safety plug connected. 18. The method of claim 17, wherein coupling the first ordnance controller and the second ordnance controller includes coupling at least one power signal line from the second safety plug to the first safety plug. 19. A method for controlling initiation of an energetic material, the method comprising: sending a control signal over a common communication bus to a plurality of ordnance controllers operably coupled to a plurality of firing units configured to ignite the energetic material, the control signal including a message including an address corresponding to the firing unit to be armed and charged; and sending a power signal over a common power bus to the plurality of ordnance controllers through safety plugs that correspond to an associated ordnance controller for manually disconnecting the power signal, the plurality of ordnance controllers further configured for providing the power signal to the firing unit to be armed and charged. 20. The method of claim 19, further comprising sending a fire command signal to the firing unit after being armed and charged. 21.
