Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).

Developments in conventional submarine propulsion, namely, air-independent propulsion (AIP) systems and lithium-ion batteries, could be a game changer, and navies that operate solely nuclear-powered submarines might reconsider including advanced conventional submarines in …

2004年11月29日 · As interest mounts in "Air-Independent Propulsion" (AIP) for enhancing the performance of small, defensive submarines, a serious new underwater threat is developing in littoral waters.

U.S. naval nuclear propulsion plants use a pressurized-water reactor design that has two basic systems: the primary system and the secondary system. The primary system circulates ordinary water...

2025年1月22日 · All types of advanced conventional AIP propulsion systems, whether fuel cell, Stirling engine, or steam turbine based, offer extended submerged endurance to small and medium size submarines when compared with traditional diesel-electric propulsion systems, such as that fitted to the Project 636M Kilo-class China imported from Russia. The latter ...

2024年5月7日 · Explore the evolution, types, and future trends of submarine propulsion systems, and understand their critical role in naval warfare and submarine design efficiency.

2023年7月3日 · The incorporation of lithium-ion batteries into diesel-electric submarines will provide a hybrid propulsion capability and significantly reduce the acoustic signature of a submarine, making it harder to detect.

2024年5月3日 · By the mid-20th century, nuclear power became a truly efficient propulsion system for submarines. After years of experimenting, it became clear that nuclear power held the answer to propulsion, habitability, and strategic problems that plagued earlier boats. By removing the necessity to surface for air replenishment and battery recharge ...

To mitigate this problem, modern diesel submarines are fitted with air-independent propulsion (AIP) for use when patrolling the operational area. AIP systems convert chemical energy (typically from hydrogen) into electric power at relatively high …

2024年12月21日 · The Japanese I-201 class was a high-speed submarine, of 259 feet and 1,291 tons displacement, that had diesel propulsion for 15 knots on the surface; while underwater, large batteries and electric motors could drive the vessel at a speed of 19 knots for almost one hour.
