By re-liquefying it to be stored in the liquefied oxygen tank or provided as breathing oxygen in the vessel, it is not affected by the depth of submersion, it can improve fuel efficiency and greatly improve the operational capability, and minimize the discharge of oxygen to the outside It relates to a submarine equipped with an independent air propulsion system that has a structure that does not expose the position to the enemy because there is no bubble on the surface, and also reduces the running cost.

일반적으로, AIP시스템이 탑재된 잠수함으로는 연료전지 방식, 스털링(Sterling) 엔진 방식, MESMA(Module d'Energie Sous-Marine Autonome) 방식 및 폐회로 디젤엔진(CCD, Closed-Cyde Diesel engine) 방식을 갖는 4가지 종류가 있다.In general, submarines equipped with AIP systems have a fuel cell method, a Stirling engine method, a MESMA (Module d'Energie Sous-Marine Autonome) method, and a closed-loop diesel engine (CCD) method. There are four kinds.

AIP 시스템이란 대기중의 공기에 의존적이지 않은 추진체계로서, 원자력이 아니면서도 기존의 디젤 잠수함 보다 잠항 시간을 연장시킬 수 있는 추진체계이며, AIP 시스템의 잠수함은 디젤 잠수함의 가장 취약점인 스노클 없이 임무해역에서 수 노트로 수주 동안 잠항 항해를 지속할 수 있고, 이러한 AIP 시스템을 작동시키기 위해서는 연료인 산소가 필수적으로 필요하다.The AIP system is a propulsion system that is not dependent on the air in the atmosphere. It is a propulsion system that can extend the dive time than the existing diesel submarines without the nuclear power. Submerged voyages can last from weeks to weeks, and oxygen, the fuel, is essential to operate this AIP system.

종래의 AIP 시스템이 탑재된 잠수함은 액화산소를 저장하기 위한 액화산소저장탱크를 구비하고 있으며, 액화산소탱크 내에 저장된 산소는 잠수함의 작전능력을 결정하는 중요한 요소이다.Submarines equipped with conventional AIP systems have a liquefied oxygen storage tank for storing liquefied oxygen, and oxygen stored in the liquefied oxygen tank is an important factor in determining the operational capability of the submarine.

상기 액화산소저장탱크 내에 저장된 액화산소는 일정시간이 되면 액화산소가 기화되어 탱크의 압력이 상승하게 되며, 운용자는 탱크의 압력을 항시 모니터링 하면서 탱크의 압력이 예정된 압력에 도달하면 즉시 기화된 산소가스를 함의 외부로 배출하거나 함 내의 호흡용으로 제공한다.The liquefied oxygen stored in the liquefied oxygen storage tank is liquefied oxygen vaporizes at a certain time to increase the pressure of the tank, and the operator monitors the pressure of the tank at all times and immediately vaporizes the oxygen gas when the tank pressure reaches the predetermined pressure. To be discharged to the outside of the enclosure or for breathing within the enclosure.

상기와 같은 종래의 AIP 시스템이 탑재된 잠수함은 액화산소저장탱크 내의 압력이 기화된 산소로 인해 예정치에 도달하면 산소가스를 함의 외부로 배출시켜는 블로우 오프(Blow off)를 실시하여야 함으로 잠항 심도에 제한이 있고, 이에 따라 수면이 기포가 발생되어 함의 위치가 적에게 노출될 수 있으며, 일정시간이 되면 액화산소는 지속적으로 기화되고, 이에 따라 액화산소탱크 내의 기화된 산소를 예정된 압력에 도달하면 계속 배출시켜야 함은 물론, AIP 시스템을 사용하지 않을 때에도 안전을 위해 기화된 산소가스를 배출시켜야 함으로, 작전 시 저장산소의 불필요한 소모가 많아 작전능력이 현저히 저하됨은 물론 운용비용도 높다는 문제점이 있었다.The submarine equipped with the conventional AIP system as described above has a depth of submersion when the pressure in the liquefied oxygen storage tank reaches a predetermined value due to vaporized oxygen, so that the oxygen gas is blown off to the outside of the vessel. There is a limit to this, and the surface of the water bubble is generated, the position of the ship can be exposed to the enemy, the liquid oxygen is continuously vaporized at a certain time, so that when the oxygenated oxygen in the liquid oxygen tank reaches the predetermined pressure Not only should it continue to be discharged, but even when the AIP system is not used, gaseous oxygen gas must be discharged for safety. Therefore, there is a problem that the operation capacity is significantly reduced and the operation cost is high due to the unnecessary consumption of storage oxygen during the operation.

There is no restriction on the depth of seam due to position exposure and blow-off due to air bubbles, and the operation period can be significantly increased while doubling the ship's operational capacity by significantly extending the seam period by minimizing oxygen consumption without releasing oxygen gas. It is to provide a submarine equipped with an external independent propulsion system that can be lowered.
