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, Kafe, Webinar 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.

초록

This disclosure relates to self-contained cartridges and launcher systems for discharging or launching payloads to downrange targets, and methods of attenuating or offsetting recoil when activating such cartridges. Examples of payloads that can be deployed with the disclosed launcher apparatus include chemical, biological, pyrotechnic, marker, tracer, signaling, non-lethal, explosive, smoke, and similar payloads.

1. A self-contained cartridge comprising: a) a cartridge case having a forward end and an aft end and a uniform diameter extending from the forward end to the aft end, wherein the forward end has a closed configuration and an open configuration;b) a primer situated at the aft end of the cartridge case;c) a propellant adjacent the primer; andd) a payload;wherein the open configuration of the forward end comprises a tapered nozzle formed from the cartridge case when the cartridge opens during launching of the payload, and the diameter of the nozzle opening is less than the inner diameter of the cartridge case, and wherein the forward end of the cartridge case which forms the tapered nozzle is crimped in the closed configuration;wherein the nozzle is configured to force a desired pattern of the payload; andwherein the tapered nozzle of the open configuration forms in the absence of a nozzle-shaped chamber. 2. A self-contained cartridge according to claim 1, further comprising an obturating component between the propellant and the payload. 3. A self-contained cartridge according to claim 2, wherein the obturating component is a granular obturating medium or a pre-shaped gas seal. 4. A self-contained cartridge according to claim 1, further comprising a granular obturating medium between the propellant and the payload, wherein the self-contained cartridge does not include a pre-shaped gas seal. 5. A self-contained cartridge according to claim 1, wherein the payload is selected from chemical, powder, gel, fire suppression, pyrotechnic, marker, tracer, signaling, explosive, smoke, incendiary, biological, heat insulating, anti-chemical warfare, anti-biological warfare, liquid-containing, powder-containing, or gel-containing payloads. 6. A self-contained cartridge according to claim 1, wherein the self-contained cartridge is selected from a flare cartridge, a smoke cartridge, a smoke flare cartridge, a signaling device cartridge, a chemical cartridge, a biological cartridge, a distraction device cartridge, a pyrotechnic cartridge, a marking cartridge, an incendiary cartridge, a tracer cartridge, an anti-chemical warfare cartridge, or an anti-biological warfare cartridge. 7. A self-contained cartridge according to claim 1, wherein the closed configuration of the forward end of the cartridge case comprises a star crimp or a roll crimp. 8. A self-contained cartridge according to claim 1, wherein the tapered nozzle forms when the cartridge opens during launching of the payload at less than or about 400 ft/sec. 9. A method of launching a payload, the method comprising: a1) providing self-contained cartridge according to claim 1; andb) striking the primer with or on any object with sufficient force to activate the primer and to offset at least a portion of the recoil resulting from launching the payload. 10. A method of launching a payload according to claim 9, the method further comprising: a2) providing a payload launcher system comprising: i) a launcher tube having an open nozzle end and an aft end;ii) a cap removably-attached to the aft end, the cap comprising a firing pin opening and a forward- and rearward-movable firing pin, wherein the firing pin protrudes through the firing pin opening in its forwardmost position; andiii) a chamber within the launcher tube adjacent the firing pin opening adapted for receiving the self-contained cartridge; anda3) inserting the self-contained cartridge in the chamber and attaching the cap to the aft end of the launcher tube;wherein the step of striking the primer comprises striking the firing pin with or on any object with sufficient force to activate the primer and to offset at least a portion of the recoil resulting from launching the payload. 11. A method of launching a payload according to claim 9, wherein the payload is launched with a muzzle velocity of less than or about 400 ft/sec. 12. A method of launching a payload according to claim 9, wherein the self-contained cartridge further comprises an obturating component between the propellant and the payload. 13. A method of launching a payload according to claim 9, wherein the payload is selected from chemical, powder, gel, fire suppression, pyrotechnic, marker, tracer, signaling, explosive, smoke, incendiary, biological, heat insulating, anti-chemical warfare, anti-biological warfare, liquid-containing, powder-containing, or gel-containing payloads. 14. A method of launching a payload according to claim 9, wherein the self-contained cartridge is selected from a flare cartridge, a smoke cartridge, a smoke flare cartridge, a signaling device cartridge, a chemical cartridge, a biological cartridge, a distraction device cartridge, a pyrotechnic cartridge, a marking cartridge, an incendiary cartridge, a tracer cartridge, an anti-chemical warfare cartridge, or an anti-biological warfare cartridge. 15. A self-contained cartridge comprising: a) a cartridge case having a forward end and an aft end and a uniform diameter extending from the forward end to the aft end, wherein the forward end has a closed configuration and an open configuration;b) a primer situated at the aft end of the cartridge case; andc) a payload;wherein the open configuration of the forward end comprises a tapered nozzle formed from the cartridge case when the cartridge opens during launching of the payload, and the diameter of the nozzle opening is less than the inner diameter of the cartridge case, and wherein the forward end of the cartridge case which forms the tapered nozzle is crimped in the closed configuration;wherein the nozzle is configured to force a desired pattern of the payload; andwherein the tapered nozzle of the open configuration forms in the absence of a nozzle-shaped chamber. 16. A self-contained cartridge according to claim 15, further comprising an obturating component between the primer and the payload. 17. A self-contained cartridge according to claim 16, wherein the obturating component is a granular obturating medium or a pre-shaped gas seal. 18. A self-contained cartridge according to claim 15, further comprising a granular obturating medium between the primer and the payload, wherein the self-contained cartridge does not include a pre-shaped gas seal. 19. A self-contained cartridge according to claim 15, further comprising a propellant between the primer and the payload. 20. A self-contained cartridge according to claim 15, wherein the closed configuration of the forward end of the cartridge case comprises a star crimp or a roll crimp. 21. A self-contained cartridge according to claim 15, wherein the payload is selected from chemical, powder, gel, fire suppression, pyrotechnic, marker, tracer, signaling, explosive, smoke, incendiary, biological, heat insulating, anti-chemical warfare, anti-biological warfare, liquid-containing, powder-containing, or gel-containing payloads. 22. A self-contained cartridge according to claim 15, wherein the self-contained cartridge is selected from a flare cartridge, a smoke cartridge, a smoke flare cartridge, a signaling device cartridge, a chemical cartridge, a biological cartridge, a distraction device cartridge, a pyrotechnic cartridge, a marking cartridge, an incendiary cartridge, a tracer cartridge, an anti-chemical warfare cartridge, or an anti-biological warfare cartridge.
