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).

2016年7月6日 · The introduction of Air Independent Propulsion (AIP), vastly improved the underwater endurance of these submarines and gave them a distinct advantage. That is the reason we see a large number of navies queuing up to buy or build submarines with AIP systems.

不依赖空气推进（英文：Air-Independent Propulsion；AIP、亦称：不倚赖空气推进），是指无需获取外间空气中氧气的情况下能够长时间地驱动潜艇的技术。 使用该技术的潜艇的自持力比一般柴电潜艇的大一倍以上，也即连续的潜航时间及潜航距离较长，但仍比核潜艇 ...

The S80-class incorporates a novel air-independent propulsion (AIP) system, which generates electrical power from a fuel cell. The oxygen required by the fuel cellis stored in a tank in liquid form, while the hydrogen, much more volatile and dangerous, is obtained in a reformer via chemical reactions that use ethanol as reactant.1 A separate ...

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. Increasingly, smaller nations unwilling or unable to …

Air-independent propulsion (AIP) is the answer. Our proven HDW fuel cell system delivers a unique AIP solution for direct integration into non-nuclear submarines. Fuel cells are energy converters that transform chemical energy directly to electrical energy without noise or …

In an anaerobic vessel, an Air Independent Propulsion (AIP) system is added to the power plant, in which a diesel motor powers an electric motor. It is the system used to provide propulsion in immersion and, occasionally, to recharge cells.

2024年5月5日 · AIP is mostly implemented as an auxiliary source, with the traditional diesel engine handling surface propulsion. AIP technology can be installed on existing, older-generation submarines by inserting a new hull section during a retrofit. A typical conventional power plant provides 3 megawatts maximum, and an AIP source around 10 percent of that ...

2024年1月17日 · Air-independent propulsion (AIP) has ushered in a new era for diesel-electric submarines, making them more lethal, stealthier, and capable of enduring extended underwater deployments. With the global proliferation of AIP technology and ongoing advancements, submarines equipped with AIP systems are poised to play a crucial role in modern naval ...

2023年7月31日 · This article provides an in-depth understanding of Air-independent Propulsion (AIP) technology, its usage in non-nuclear submarines, and its role in enhancing underwater endurance and stealth. It also explores the different types of AIP systems and the DRDO's contribution to AIP technology.
