ALSTOM Power Conversion Incorporated (APCI) reports that the DD(X) Integrated Power System (IPS) Test Team has achieved full torque of over 1,000,000 foot pounds on the Advanced Induction Motor (AIM) at the NGSS, NSWC Land Based Test Site in Philadelphia. This AIM is rated at 18.25MW at 127 RPM.
Under contract with Northrop Grumman Ship Systems, ALSTOM's propulsion solution includes the power dense motor controller called a VDM25000 and the Advanced Induction Motor. Both of these components have achieved full power during the testing. This propulsion system is the most power dense package demonstrated at full scale to designed torque and is now ready as the main propulsion solution for DD(X).
"The IPS is a vital element of the DD(X) design." affirmed Brian Cuccias, Northrop Grumman Vice President and DD(X) Program Manager. "Successfully completing these tests verifies key performance parameters set by the US Navy and further demonstrates the added capabilities this ship will bring to the joint maritime force. We have a power solution for real naval transformation."
ALSTOM has won a second order of around €80 million (£54 million) to supply an integrated electric power and propulsion system for the Royal Navy’s Anti-Air Warfare Type 45 Destroyers.
Following on from the first contract in April 2001 for batch one, this order is for batch two vessels and was awarded by BAE SYSTEMS Type 45 Destroyer Prime Contract Office.
Secured by ALSTOM’s Power Conversion business, based in Rugby, UK, the order for the integrated electric power and propulsion system also includes the supply of major items of equipment including: 21 MWe alternators, 2MW diesel generator sets, HV switchboard, service transformers, VDM25000 PWM drives, 20MW 15 phased advanced induction motors (AIM), harmonic filters and the electrical power management system.
The first Type 45 Destroyer will be a world leader among air defence warships.
Integrated electric power and propulsion offers the potential benefits for through-life cost, reduced maintenance and greater operational flexibility. The T45 vessels will be the first front-line warships in the Royal Navy to have this type of system which has undergone successful extensive testing at ALSTOM’s Electric Ship Technology Demonstrator (ESTD) in Whetstone, near Leicester, UK, as well as being the first-of-class propulsion converters and advanced induction motors tested in back to back configuration.
