This paper describes recent design changes in the RB211-524 powerplant. In response to the market requirement for a wide bodied aircraft to make journeys of increased range, the specific fuel consumption of the latest -524 engine has been improved by 14% compared with initial versions. The paper shows how the potential of the three shaft concept has been coupled with the latest aerodynamic technology to produce over 25% more thrust at essentially the same engine size. This increased thrust has been achieved while meeting the latest noise and gaseous emissions regulations and while achieving continuing improvements in engine reliability. The paper describes the introduction of electronic engine control to provide improved aircraft operation and maintenance. It also shows how the needs of the latest wide body, long range, twin engined aircraft unter development can be met by combining the core of the -524 engine with a larger fan to produce a powerplant with a further 25% increased thrust capability.
