  2. Air-independent propulsion - Wikipedia

    en.wikipedia.org/wiki/Air-independent_propulsion

    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). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

    The German Type 212 submarine was the first series production submarine to use fuel cells for air-independent propulsion. It is powered by nine 34-kilowatt hydrogen fuel cells . Most small modern commercial submarines that are not expected to operate independently and use batteries that can be recharged by a mother-ship after every dive.

    These two submarines were originally launched as Västergötland-class submarines in 1987 and 1990, and were relaunched as a new class after extensive modernization in 2003 and 2004 by Kockums AB. The pressure hull had been cut in two after the sail and a 12 m (39 ft 4 in) long new section with an air-independent propulsion system was inserted.

    He designed submarines of the Dekabrist, Leninets, and Shchuka classes. Another milestone of the era came in 1935, when Central Design Bureau engineer S.A. Bazilevskiy proposed an air-independent propulsion system which allowed engine operation based on the closed cycle REDO in both surface and submerged submarine conditions. Experiments on ...
