Abstract:
A submarine is a vehicle which travels underneath the sea surface by varying its buoyancy.
They are powered by diesel engines, whose drawbacks to a large extent are now overcome by
nuclear reactors. It travel into the sea by means of ballast tank, so the design of ballast tank is
one of the most important aspect. It should be design in such a way that the submarine should
submerged by partially filling the ballast tank. In this project, we have designed and developed
a density variation mechanism of submarine using air chamber and ballast tank. We use the
rolling pump which plays a vital role in this mechanism which helps to suck and discharge
water into the ballast tank. This helps the submarine to sink inside the water and float it back
to surface. In addition, we also implement the pressure relief valve to overcome the drawback
of the excess pressure generated in the air chamber and the navigation system which will help
the submarine to take a turn in left and right direction. Surely the ballast tank is an engineering
master piece that has proved its purpose and might over the years Submarine is a vehicle which
travel underneath sea surface by varying its buoyancy. The world is looking forward to seeing
the newer changes in the submarine technology.
The paper is an effort to look into the engineering aspects of a ballast tank which includes
construction details, submerging of submarine, and different mechanism for achieving the task.
