GRAHAM HAWKEES AND UNDERWATER FLIGHT post by Virquan Harold

Hey bloggers! Have any of you guys heard of Graham Hawkes? Well, his subs are currently the holder of the deepest recorded dive of 36,000 feet. His submarines are actually like airplanes that can go underwater. The interesting thing about this is the MATERIAL! Their underwater vehicles actually are positively buoyant and they use propellers to dive. The buoyant forces want to push it back to the surface. If they would turn their propels off, they would float back up to the surface unlike traditional submarines that are immensely heavier than water. The Deep Flight Challenger was one of there most interesting subs because it was designed to go down the deepest trench in the world, the Mariana, and engineering the material for that was so key because of the immense pressure. Just think about 60,000 pounds of pressure pushing down on you; you would be flat as pancakes or even thinner. The actual hull was made out of a custom-designed carbon fiber and it is said that the pilot would not be subjected to any pressure difference when diving. Its interesting to wonder the process of designing the material and how they came up with the material to be used.

It is pretty cool website and it shows some of the different underwater vehicles his has built.
