Rolls Offers RB3025 For New Triple Seven

An all-new RB3025 engine concept has been created by Rolls-Royce following a Boeing request also extended to General Electric and Pratt & Whitney for a powerplant for a future 777-size aircraft in around 2020. The current 777 is powered exclusively by the GE90.

Rolls-Royce has selected a 132.5-inch diameter for the composite fan for the 99,500-pound-thrust engine, which will sport a 12:1 bypass ratio and a 62:1 overall pressure ratio that would be the highest achieved on a commercial aircraft.
