What is AIP in submarine?
The air-independent propulsion (AIP) technology enhances the underwater endurance and stealth of conventional submarines who otherwise have to come on the surface to use oxygen to recharge their batteries.
How do submarine engines work without air?
When the sub is submerged there are no exhaust gases, because the diesel engines don’t work – under water there’s no air for the engines to ingest, compress and burn the fuel with. Under water the sub runs on batteries which are charged only when the submarine is on the surface.
How does a submarine propulsion work?
Submarine Propulsion. Steam turbines propel nuclear-powered submarines. Heat from the nuclear reactor, regulated from consoles in the maneuvering room, generates the steam that drives the turbines, which are geared to a propeller shaft. The rotating propeller drives the submarine through the water.
How is air produced on a submarine?
Atmosphere inside submarines is very carefully monitored and controlled. Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.

How does a pump jet work on a submarine?
A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle.
What is air independent propulsion in a submarine?
Air-independent propulsion. Air-independent propulsion (AIP) is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).
What is air independent propulsion (AIP)?
The system is being developed by the Naval Materials Research Laboratory (NMRL) of DRDO.” What is Air Independent Propulsion Technology? Air-independent propulsion (AIP), or air-independent power, is marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).
What is the function of the AIP in a submarine?
AIP is usually implemented as an auxiliary source, with the traditional diesel engine handling surface propulsion. Most such systems generate electricity which in turn drives an electric motor for propulsion or recharges the boat’s batteries. The submarine’s electrical system is also used for providing “hotel…
Why is closed cycle diesel AIP not used in modern submarines?
Closed Cycle Diesel AIP is hence not preferred for modern submarines even though it is comparatively cheaper and simplifies logistics by the use of standard diesel fuel. Steam turbines make use of a source of energy to heat water and convert it into steam in order to the run the turbine.
