Submarines could ditch propellers

August 1st, 2007

Submarines could ditch propellers Nature has always provided scientists with inspiration when it comes to designing a product, and this time we have the movements of a bluegill sunfish that will be used to develop an agile, propellerless submarine. These prototype mechanical fins are meant to recreate the fish’s powerful forward thrust and its manoeuvrability that will go a long way in helping improve the mobility of underwater vehicles. The benefits are endless, as fish-like submarines can then map oceans, survey shipwrecks, and even sweep for mines with more agility and speed compared to the best that we have on offer today. It will take around two more years before a fully working underwater vehicle prototype will be made available.
