This paper describes the fuel-efficient RB211-535E4 third generation turbo fan. Competitive fuel efficiency is obtained with a derivative engine through improved component efficiency. The change has been concentrated in modules where the scope for advancement is a maximum, whilst minimising the consequential changes with their attendant risks and high costs.The theme is one of improving component efficiency through a progressively deeper understanding of the loss-making processes. Good theoretical design procedures are backed by very accurate and perceptive instrumentation to study the aerodynamic processes at the physical phenomena level.The scope for further progress in fuel efficiency is indicated.
