Abstract

A submarine is
basically a watercraft that has the ability of independent operation underwater.
It is dissimilar to a submersible, which has more limited underwater power or
ability. The term most commonly refers to a large, crewed vessel. Submarines
were first widely used during World War
I (1914–1918). Submarines were first built by Dutch inventor Dribble 1633 in the early 17th century, but it was not up to 150
years later for the first time they were used in naval combat. Mostly in the Beginning
in ancient times, humans have tried to work under the water. They have tried to
work from simple submersibles to nuclear-powered
underwater crewed vessels; the humans have searched for a means to remain
safely underwater during warfare and to gain the advantage in warfare, which is
the root in the development of the submarine. This article will deal with
the working, advantages, disadvantages and application of AIP in modern
submarines and compares the Air Independent Propulsion (AIP) system with the
nuclear submarine.  An accurate
observation is that submarines designed for different missions possess
different capabilities.

INTRODUCTION AND LITERATURE SURVEY:

Ever since
submarines have become the principal weapon of naval warfare, designers have
focused on making them quieter and increasing their underwater capabilities.
Traditional diesel-electric submarines need surface so that to charge their
batteries and have the capability to remain underwater for only a few days.

 

 

As battery
technology improved, the endurance of these submarines increased
proportionally. The introduction of Air Independent Propulsion (AIP) vastly
improved the underwater endurance of these submarines and gave them distinct
advantages.

 

 

 

 

That is the basic
reason why the world is shifting to AIP system. The best part is that AIP
technology can be installed on existing older generation submarines by
inserting a new hull section during its manufacturing

 

The need for
doing now of submarine  development, as with other military systems, was
 driven by the World wars and Cold War, desire
by right improvements in sound effects, weaponry, safety, automation and submerged  power. In the years lead up to
and during World War II, over 1000 under sea boats and Diesel submarines were
 made by Germany alone (1). During times of the
Second World War, Germany was producing over 35 Diesel submarines per month. In fact, the Total number of earth submarinesmade during WVWII, not including Japan, was well over 2500 (2). Although the chief
place was on quick development and building during the
First World War and the Second World War, under-water boat
vessel designs got
well, especially in weapons and making connections systems. With the
advent of Cold War and the need for longer submerged power, the chief
place changed to nuclear submarine, causing a burst in
production of submarine vessel producing over the next 34 years. From 1955 to
1989 the Soviet Union and United
States alone made over 350 nuclear submarines (3). From a high Cold War world count 1 of 400 nuclear submarines in 1989, there are only approximately 160 today, as
nuclear submarine producing has experience
significant slowdown everywhere on worldwide (3). Building of nuclear submarines is limited to the United
States, Russia, England, France, India and China. In the us, the producing rate of 
nuclear submarines is only sent
out to be one per year over the next ten
years. While the nuclear submarine producing rate has dropped lately, Diesel electric
submarine producing rate today is growing. . The world Diesel under-water producing rate is predicted to get
stretched eight per year between 2004 and 2023 (4), 
which would increase the world Diesel submarine 1 above 500 in the
next 20 years and now this technology  is overcome by diesel
electric with AIP systems. With such systems, Diesel submarines may be suitable for
coastal defense and hence they can easily operate in
oceans. Diesel submarine buildings and structure design vary
according to country to country and type of missions.

.And the Swedish industrialist Thorsten nordenfelt led to  the first useful steam-powered under-water, armedwith torpedoes and ready for military use.
 The first was nordenfelt I, a 56-tonne, 19.5-metre (64 ft) vessel like to Garrett’s ill-fated resurgam (1879), with a range of 240 kilometres 2 (130 nmi; 150 mi  armed with a single torpedo, in 1885.

a safe, good,
ready meansof propulsion 3 for the submerged vessel was only made possible in the 1880s with advent
of electric battery for producing electric
current technology. The first with
electrics powered boats were made by IsaacPeral Y 4  Caballero in Spain, Dupuy de Lome and Gustave Zede in France, and James Franklin Waddington in England. 12 Peral’s
design marked torpedoes and other systems that later
became quality example in submarine 13

Submarines were not put into arm for any stretched

The Irish inventor
John Philip Holland made a design to 
submarine in 1876 and a full-scale account in 1878. In 1896 he designed
the Holland sort V1 submarine, which used internal combustion engine power on
the top and electric apparatus for producing electric current power underwater.
on 17 May 1897 at Navy Lt. Lewis Nixon’s crescent  Shipyard in Elizabeth, New Jersey, Holland VI
was purchased by the United States Navy on 11 April 1900, becoming the navy’s
first commisioned submarine 14The Royal Navy given payment for trade five
Holland-class submarines from vickers barrow-in-furness under licence from the
Holland torpedo Boat Company from 1901 to 1903.

 

As their name suggests,
diesel-electric submarines run on Diesel and electrics. They have a greatly
sized network 1 of electric units which are charged by the Diesel generator.
They snorkel, which means, journeying just below the top of the water with the
periscope 2 and the Diesel generator make  pipe above the water top. Once they charge
their batteries, they dive into ocean and run silently on battery power and
their diesel generators are shut down underneath water, After running low
batteries for a few days underwater, the submarines come to surface for
recharging their batteries. diesel-electric submarines are also has relation to
as SSK (sub-surface   Hunter-Killer) by us naval.

 underwater, the batteries run out of charge
within 4-5 days and the submarine needs to recharge them quickly.this is
basically done by snorkeling which is also an alarm of danger .so that the
submarine is detected by redar and easy target for hostile anti-submarine.but now
a days snorkel are coated with radar absorbing paint and have a secure shaping
but it can be sensed by high resolution radars. now there are also diesel
sniffers that can detect a submarine during its exhaust emission while
snorkeling.the submarines have to come to surface for recharging in this way
they loses their efficiency and increases its suspection to hostile
anti-submarine assets.

Hence we need a
system which can let diesel-electric submarines to power up again their
electric units without running their engines. This will let them to continue
sailing underwater  and in this way they make
less possibility to be detected.The system should also let the SSKs to greatly
low noise. The system which permits all this is Air independent propulsion (AIP).

Although nuclear
submarines offer far better power and speeds , they are quite unsuitable where
the level of water is less and most of navies cant afford to manufactured and
to maintain them as they are very expensive. Also Diesel submarines have the
ability to switched off their engine and lie in water while nuclear submarine
cant switched of their reactors at will. as This grouped together with the
ultra-quiet nature of-the Diesel subs, has made AIP-equipped Diesel subs a very
attractive that possibly taking place in addition for many countries. Many
countries are operating both nuclear and diesel-powered submarines for their
advantages. Navies who wants to operate non-nuclear submarines having longer
–range and large weapons are now option for large diesel submarines having
AIP,which is closest to nuclear powered submarines. Some examples are the Soryu class of Japan, Type
216 being developed by Germany and the Shortfin Barracuda of
France which will be operated by Australia.
