Rolls-Royce has won a share of an order from China Eastern Airlines for V2500 engines to power 50 new Airbus A320 series aircraft.
The contract, worth more than $400m (£255m) to Rolls-Royce, includes a long-term engine maintenance agreement.
Deliveries will commence in August 2012, continuing to 2015, and China Eastern will employ the V2500s to expand the capacity of its fleet.
The V2500 is produced by the International Aero Engines consortium (IAE) in which Rolls-Royce is a senior shareholder. IAE’s other partners are Pratt & Whitney, the Japanese Aero Engines Corporation and MTU Aero Engines.
