Physics of Submarines Essays -- physics submarine

Submarines have been around for longer than most people think. The first American attempts at creating a submersible boat date back to the days of the Revolutionary and Civil Wars. These boats, however, turned out to be just as dangerous to the people on board as they were to the enemy boats. So the concept was put aside for a while. But in the 1890's two men named John Holland and Simon Lake built a practical underwater boat. The US Navy bought its first submarine from Mr. Holland on April 11, 1900, a date which is thought of as the birthday of the US submarine force. Submarines progressed in technology throughout the years and were used extensively and quite successfully in both world wars. The major breakthrough in submarine technology came in the next ten years after the war, when nuclear propulsion was developed. Early submarines were driven by big diesel engines. These engines provided plenty of power for turning the propellers to drive the sub as well as a way to heat the sub and provide electricity. There were however a few drawbacks, fuel economy and the ability to stay underwater for long periods of time. In order to run a diesel engine, you of course need diesel fuel and lots of it. This was a problem since you could only carry so much fuel on a ship. Also diesel engines give off emissions. This was not a problem as long as the submarine was on the surface. When they dove, however, there was only a limited amount of space in which you could pump the fumes before you had to surface and vent. You also need an oxygen intake from the surface. Both of these problems were solved, however, by nuclear power. The world's first nuclear powered submarine was an American boat called the USS Nautilus, which was p... ... . 2) Freudenrich, Craig, Ph. D., and Marshall Brian.
