A typical conventional power plant provides 3 megawatts maximum, and an AIP source around 10 per cent of that. A nuclear submarine\u2019s propulsion plant is much greater than 20 megawatts.<\/li>\n<\/ul>\n<p><strong>Key features of the AIP system:<\/strong><\/p>\n<ul>\n<li>It allows the submarines <strong>to stay for longer hours in water<\/strong>. The submarines need to come to the surface of the water to charge their batteries. This is reduced by AIP System.<\/li>\n<li>It <strong>decreases the noise levels<\/strong> made by the submarines. This makes it hard to detect the submarines.<\/li>\n<li><strong>Types of AIP:<\/strong> Open-cycle systems, Closed-cycle diesel engines, Closed-cycle steam turbines Stirling cycle engines and Fuel cells.<\/li>\n<\/ul>\n<p><strong>What are the types of Submarines?<\/strong><\/p>\n<ul>\n<li><strong>Conventional or Diesel-electric submarine:<\/strong> They need atmospheric oxygen to run the diesel generator which in turn charges the batteries.<\/li>\n<li><strong>Nuclear Submarine:<\/strong> It is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. They have considerable performance advantages over conventional submarines.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<hr \/>\n<h3><strong>Q1) What is Submarines?<\/strong><\/h3>\n<p>Submarines are watercraft that are designed to operate underwater. They are a type of naval vessel that is capable of independent operation beneath the surface of the water. Submarines are used for various purposes, including military, scientific research, exploration, and rescue missions.<\/p>\n<p><strong>Source:<\/strong>\u00a0<a href=\"https:\/\/economictimes.indiatimes.com\/news\/defence\/lt-drdo-sign-contract-for-aip-system-for-submarines-of-indian-navy\/articleshow\/101187577.cms\" target=\"_blank\" rel=\"nofollow noopener\"><u>L&amp;T, DRDO sign contract for AIP System for submarines of Indian Navy<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Air Independent Propulsion (AIP) System allows the submarines to stay for longer hours in water.<\/p>\n","protected":false},"author":5,"featured_media":12476,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-12475","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/12475","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=12475"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/12475\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/12476"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=12475"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=12475"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=12475"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
