The Engine

As a member of the RB211 family, the RB211-535 is built on sound fundamentals:

Three-shaft architecture
The three-shaft architecture, first introduced on the RB211-22B, allows an engine to have fewer stages giving a shorter, stiffer structure. This ambitious and innovative technology allows the rotors to run to their optimum speeds thereby reducing the need for compressor variable guide vanes.

Reliability as standard
The RB211-535E4 has the lowest combination of in-flight shutdown rate and shop visit rate in the airline industry, a factor that has resulted in the RB211-535E4 being the airlines first choice to power the Boeing 757. The RB211-535E4 achieved the world record for on-wing life without removal for over 40,000 hours over nine years in operation. This is equivalent to 18,000,000 miles flown, or 37 return trips to the moon. It stays on wing almost twice as long as any other engine on the airframe.

Incorporating Trent technology
Through the Rolls-Royce concept of family designs, the RB211-535E4 was upgraded with Phase 5 combustor technology from the 04 HP (high pressure) module developed on the Trent engine family. This further improved the class-leading environmental position on the Boeing 757.

Best environmental credentials
The RB211-535E4-powered Boeing 757 is the quietest airliner in its class, meeting both Chapter 3 and Chapter 4 limits with a large margin, allowing it to power aircraft in and out of airports with strict local noise limits.

This coupled with Phase 5 combustion technology makes the RB211-535E4 the most environmentally friendly engine for the Boeing 757 and the Tupolev Tu-204.
