Rolls-Royce plans two new, more efficient engines
British engineering company Rolls-Royce has said it plans to build a new aircraft engine which it said would be up to 6% more efficient than its latest model and could be ready by the end of the decade, Reuters has reported. The world’s second-largest maker of aircraft engines behind US group General Electric said the new engine, which it called “Advance,” could be a successor to its Trent XWB which is due to enter service later this year. By 2025, Rolls said an even newer model, the “UltraFan,” could be ready to be attached to an aircraft. This would be around 10% more efficient than the Trent XWB, it said.
