Design and development of density variation mechanism of submarine

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.
