Rolls-Royce workers at Barnoldswick were today celebrating a double helping of Eastern delight after the company won a second multi-million-pound contract win.

Just 24 hours after securing a billion dollar order from Japanese airline All Nippon for engines for 50 new passenger jets, Rolls-Royce announced a $450 million deal with China Eastern Airlines.

Together, the two contracts are worth around £800 million to Rolls-Royce with a "significant" proportion of the work destined for East Lancashire.

Its two plants in Barnoldswick, which employ more than 800 people, manufacture the fan blades and other key components for the Rolls-Royce Trent family of engines.

While there will be no new jobs created at Barnoldswick, a Rolls-Royce spokesman said the order would help to safeguard the long-term future of the site.

"This is wonderful news for Rolls-Royce and for our operations in Barnoldswick," he said. "Contracts like these help to underpin the future of the business and there will be a significant share of the work for Barnoldswick."

China Eastern Airlines has ordered Trent 700 engines to power 20 Airbus twinjets.

The airline currently has five Trent 500-powered Airbus aircraft which, when they first entered service last year, were the first Trent engines delivered to mainland China.

Charles Cuddington, managing director of the Rolls-Royce Airlines business said: "China continues to be a key market for Rolls-Royce and, as one of the country's top three airlines, we are delighted to see China Eastern again choose Trent power."

All Nippon is buying the Boeing 7E7 Dreamliner which is scheduled to go into service in 2008. Rolls-Royce fought off opposition from US aerospace giant General Electric to power the new plane.

All Nippon, Japan's number two airline said its engine selection committee chose Rolls-Royce's Trent 1000 because it was highly rated in terms of safety, reliability, fuel efficiency, noise and emissions.
