Description

The foundation for the Trent family
Providing power to the Boeing 747 and 767.

The RB211-524G/H&-T engine powers over 75 aircraft in service today and is the first engine ever to achieve more than 27,500 hours on-wing.

Saving fuel through low deterioration
Since 2001, the RB211-524G/H-T has been providing Boeing 767 owners with the lowest possible cost of ownership.


In the RB211-524G/H & -T the HP turbine system is designed to operate at Trent 700 temperatures that are significantly higher than the original RB211-524. Because of this, the engine is able to better retain its performance characteristics throughout its service life.


The RB211-524G/H & -T offers full commonality and engine changeability for a Boeing 747 and Boeing 767 mixed fleet. This results in lower spares holdings and added value for customers.

Technology
The three-shaft architecture allows an engine to have fewer stages, giving a shorter, stiffer structure that allows the rotors to run at their optimum speeds.
The innovative wide-chord fan blades allow a reduction in the number of total fan blades - increasing efficiency, reducing noise and giving unrivalled protection against foreign object damage.
Through the Rolls-Royce concept of family designs, the RB211-524G/H-T was upgraded with 04 module HP (high pressure) technology developed on the Trent 700 engine family in 1997.
In the RB211-524G/H-T, the HP turbine system is designed to operate at Trent 700 temperatures that are significantly higher than the original RB211-524.
The Trent style combustor reduces NOx emissions by 40 per cent, making the RB211-524G/H-T the engine with the lowest NOx emissions on the Boeing 747-400.
