Fearsome Stealth Destroyer Zumwalt Becomes U.S. Navy’s First All-Electric Ship
GE – The U.S. Navy christened this month the USS Zumwalt, the largest stealth destroyer ever built for the naval service and its first modern all-electric warship.
“Traditionally, the U.S. Navy powered its ships with gas turbines driving controllable pitch propellers through large and complex gearboxes,” says Mark Dannatt, director for naval business at GE Power Conversion and a retired Royal Navy Captain.
But the new next-generation destroyer and two others in the same class will have on board a 78 megawatt power station supplying electricity to an advanced integrated power system (IPS).
The “innovative and highly survivable” system, which was designed by Dannatt’s business, powers giant GE induction motors connected directly to the propeller shafts. It also routes electricity to a vast array of sensors, weapons, radar and other critical systems on board.
“By getting rid of the gear box you can free up as much as 80 percent of the ship’s power that used to be dedicated to propulsion.” more> http://tinyurl.com/lyl9jha
