Synchrony Selected for Electric Generator for New Aero Engine

ROANOKE, VIRGINIA, May 25, 2005--Synchrony, a developer of mechanical, electronic, and software systems, was selected by Rolls-Royce to supply the electric generator and associated electronics for a new supersonic cruise missile engine.

Synchrony's components will provide conditioned electrical power for the Revolutionary Approach to Time Critical Long Range Strike (RATTLRS) vehicle. RATTLRS is under development by Lockheed Martin for the Navy, and the Allison Advanced Development Company, a subsidiary of Rolls-Royce, has responsibility for the engine. This expendable vehicle will demonstrate flight speeds between Mach 3 and Mach 4. The high speeds pose a challenge for engine components because of the high temperature of the inlet air stream to the engine.

"This contract will allow Synchrony to demonstrate its starter-generator technology in an actual flight vehicle," said Dr. Victor Iannello, Synchrony's President and Founder. "Our technology is well-suited for the supersonic flight conditions and the aggressive size and weight required for RATTLRS. Synchrony is well-positioned to become a leading supplier of advanced electrical machines and electronics for a broad range of aerospace power systems. We look forward to once again partnering with Rolls-Royce to develop and demonstrate this technology."

Synchrony's starter-generator technology was initially developed under Small Business Innovation Research (SBIR) contracts from the Air Force and NASA and later demonstrated in collaboration with Rolls-Royce as part of the Air Force's Advanced Turbine Engine Gas Generator (ATEGG) program. In contrast to conventional generators, Synchrony's starter-generator is mounted internally in the engine, eliminating the need for an external gearbox. Synchrony's starter-generator can withstand the high rotational speeds and elevated temperatures required for RATTLRS. This technology, in combination with Synchrony's magnetic bearing technology, allows engine manufacturers to design new engines without an oil lubrication system. Oil-less engines offer improved performance, life, reliability, and maintainability.

Other activities of Synchrony include the development of electronic controls and monitoring systems for automated manufacturing and for water treatment and distribution systems.
