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 film adaptation of The Hunt for Red October popularized the magnetohydrodynamic drive as a "caterpillar drive" for submarines, a nearly undetectable "silent drive" intended to achieve stealth in submarine warfare. In reality, the current traveling through the water would create gases and noise, and the magnetic fields would induce a ...
The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines. (The "Y" in the acronym was added for pronounceability.)
Nuclear power had revolutionized the Navy. The United States shared its technology with the United Kingdom, while French, Soviet, Indian and Chinese development proceeded separately. [citation needed] After the Skate-class vessels, U.S. submarines were powered by a series of standardized, single-reactor designs built by Westinghouse and General ...
Launch of the program's first submarine, the S Riachuelo (S-40), in 2018. The Submarine Development Program (PROSUB) is a partnership signed between Brazil and France in 2008, with the objective of transferring technology for the manufacture of military vessels.
The S1W reactor was the first prototype naval reactor used by the United States Navy to prove that the technology could be used for electricity generation and propulsion on submarines. The designation of "S1W" stands for S = Submarine platform; 1 = First generation core designed by the contractor; W = Westinghouse was the contracted designer
Electric thrusters are mainly used on battery operated underwater robots such as AUVs, submarines, and electric ROVs. Electric thrusters usually use brushless DC or permanent magnet synchronous motors (PMSM). These motors may be sealed within air- or oil-filled cavities, or use a flooded design that allows water to come into contact with the ...
The Type 039A submarine [a] (NATO reporting name: Yuan class) is a class of diesel-electric submarine in China's People's Liberation Army Navy. [8] It is China's first AIP powered submarine. [ 9 ] The Yuan class is the successor of the Song class submarine . [ 10 ]
