Hispano-Suiza delivers first Trent XWB power transmissions to Rolls-Royce

Farnborough, July 19, 2010 – Hispano-Suiza today announced the first deliveries of power transmissions for the Rolls-Royce Trent XWB engine. Selected by the global power systems company in July 2008, Hispano-Suiza delivered the first development shipset to Rolls-Royce in May 2010. This was, to be used for the successful first engine ground tests that took place in Derby on June 17, 2010.

"The delivery of the first development shipset was a major milestone and the culmination of remarkable work by our people ," said Olivier Horaist, Chairman and CEO of Hispano-Suiza, "and also reflects the quality of our long-term strategic relationship with Rolls-Royce."

Hispano-Suiza has teamed with Rolls-Royce for more than 20 years on the Trent family of large turbofan engines, including the Trent 500 for the A340-500/600, the Trent 700 for the A330 and the Trent 800 for the Boeing 777, as well as the BR700 series of engines for regional and business jets. Hispano-Suiza's latest success in this market is its selection as supplier of the accessory gearbox for the BR725 engine on the Gulfstream G650.

The high-technology power transmission system for the Trent XWB engine is entirely designed, developed and produced by Hispano-Suiza. It comprises the main accessory gearbox and transfer gearbox, angle driveshaft, oil tank and the high-pressure and radial driveshaft bevel
gears. Developing 800 kW of power and weighing just 100 kg (twice the power developed by the Trent 700 system at equivalent weight), this system is designed to maximize engine performance.

Hispano-Suiza is currently delivering the second power transmission system to Rolls-Royce, with 8 additional development shipsets to deliver before the end of year 2010.

At the same time Hispano- Suiza is developing power transmissions for a number of new applications, including the Trent XWB, BR725 and TP400-D6 engines, and the EC175 helicopter.
