For example this Siemens permanent magnet motor is used as a prime mover in many submarines (not sure though INS Arihant has opted for electric motor prime mover to lower noise levels)

Curious to know whether the prime mover of INS Arihant is steam turbine or is it permanent magnet propulsion motor??

Any clues???

PWR heats water to below saturation conditions in excess of 240 bar, transferring this heat to raise steam in a secondary circuit to drive the boat’s turbines, providing power to boat auxiliaries and the main propulsion system.

Reverse osmosis Desalination plants are part of submarine machinery which provides desalinated water. Nuclear Submarines require 3000psi of O2 for life support and use an electrolytic oxygen generator (EOG) to convert water into oxygen and hydrogen gases.

The Arihant sail/fin is on the conning tower as is evident from the different drawings/skeches and illustrations. Some US Navy subs have a different arrangement for their sail and no noticable humps instead a flat platform USS Nebraska http://farm3.static.flickr.com/2541/3767887379_095180f2c9_o.jpg

Rafale M Drawing

'Perhaps only the Typhoon and Rafale are the aircraft which will have a long future ahead and remain relevant if our intention is to acquire cutting edge tech' Rafale has a Naval variant (carrier launched) - Rafale M which makes it more relevant for us. Additionally, Rafales were sent to Afghanista...
