1. Objectives Preliminary design of a submarine that can operate with the water depth of H=40m — 100m in the Pacific Ocean. The submarine is a thin structure consists of a layer of steel with separate rooms. The most important rooms are: 1) Flood tanks; 2) Engine Room/Reactor; 3) Storage/Weapon room; and 4) Crew/Officer room. In this class, we focus mainly on designing the Flood tank where the water is pumped into and out of the submarine to descend or ascend.
2. Materials The submarine needs to accommodate a crew of 20 people to travel in a month uninterrupted. It needs to carry a weapon load of 2,700 kg. The steel density is chosen to be 8.05 g/cm3. The reactor weight is 100 tons. The engine is 20 tons in weight.
3. Requirements Using the system of choice , calculate and design the submarine. Please show all design computations that must cover the following: a) Room dimensions/ Wall-thickness, material density; b) Free-body diagram analysis; c) Static balances; d) Dynamic analysis.
A. Calculate the total loads of the submarine. Calculate the buoyancy force acting on the submarine with your design. B. Please show your designed system for the dimensions of the submarine, the sizes of the rooms C. Calculate force balances using free-body analysis for the hydrostatic pressures for critical points on the submarine surface .
