DRS Completes Testing Of PMM System
Parsippany NJ (AFNS) Jul 15, 2008 DRS Technologies has announced that it has successfully completed full-power testing, as required by the U.S. Navy, of its power-dense Permanent Magnet Motor (PMM) and drive at the U.S. Navy's Integrated Power System (IPS) Land-Based Test Site (LBTS) in Philadelphia, Pennsylvania. Engineering, design and development of the motor and drive were contracted to DRS as part of the DD(X) destroyer, now DDG 1000 Zumwalt-class Multi-Mission Surface Combatant, Engineering Development Model (EDM) program for inclusion into the IPS testing program. DRS' Permanent Magnet Motor provides 36.5 megawatts (approximately 50,000 horsepower) and over two million foot-pounds of torque in a dual-ring design. During testing, the motor ran at full power on a single ring at 18.25 megawatts, the maximum load available at the Land-Based Test Site. This test validated the thermal and electrical operation of the motor and drive. This milestone achievement validates that the company's Permanent Magnet Motor technology is a viable alternative for naval ship propulsion applications. DRS' Permanent Magnet Motor technology offers several benefits and advantages to the Navy over conventional ship propulsion systems, including high power density resulting in lower weight and volume than traditional motors, increased operating efficiency resulting in fuel savings, increased power and improved performance. DRS has now embarked on an enhanced design of the motor, which incorporates lessons learned from the EDM testing. The company's evolutionary motor design will provide additional benefits to the Navy, including lower weight, decreased volume and greater performance. "The validation of Permanent Magnet Motor technology is a significant milestone for the Navy and DRS," said Roger N. Sexauer, II, president of DRS' Power Systems business. "The completion of this test and our improved PMM motor design now provide the Navy with the confidence that the substantial weight, volume, cost and performance advantages of PMM technology can be realized in future ship designs."

Ocean Wind Power Maps Reveal Possible Wind Energy Sources
Pasadena CA (SPX) Jul 11, 2008Efforts to harness the energy potential of Earth's ocean winds could soon gain an important new tool: global satellite maps from NASA. Scientists have been creating maps using nearly a decade of data from NASA's QuikScat satellite that reveal ocean areas where winds could produce energy. |
