RB211-535E4 engine

[Class leader for reliability] [for Tu 204-120] [Cost effective advanced technology] [Benefits of strength by design] [Lowest shop visit rate] [Longest time in wing] [meets all environmental legislation] [gives lowest noise levels] [Simple access and maintenance] [A worldwide base]

In service with many of the world's leading airlines, the RB21 1-535E4 has a proven track record of world leading reliability and low operating costs. 
As well as the proven design and technologies in the engine, operators benefit from the extensive product and operational support available around the world from Rolls-Royce. 

-535E4. Class leader for reliability

Average time to first overhaul - 14 000 hours  Record time to first overhaul - 26 696 hours Over 800 engines in service 11 million engine flying hours experience

The RB211-535 uses advanced technology throughout its design but these technologies are introduced only where they are cost- effective and where they will bring a genuine customer benefit. 
For instance, the wide-chord fan blade gives benefits in terms of increased Foreign Object Damage (FOD) resistance and reduces the number of FOD related engine removals. Thermal barrier coatings increase turbine lives and again reduce the need for engine removals and material repair/replacement.

Class-leading reliability levels High integrity by design Proven lowest operating costs Designed-in and proven ease of maintenance Product support and overhaul capability in place around the world

The Rolls-Royce RB211 family benefits from the well-proven 'three-shaft' concept. With separate shafts for the fan/LP turbine, the IP-compressor / IP-turbine and the HP compressor/HP turbine each section of the engine is able to run at a more optimized speed. A further major benefit is that the overall number of compressor and turbine stages is substantially reduced compared with a two-shaft engine of similar thrust. This results in a more efficient engine, with fewer parts and greater reliability. The three- shaft design permits a shorter, more robust engine. Durability is further increased by the use of double casings on the compressor and turbine allowing an inner casing to carry the blade sealing system and an outer casing to carry the structural engine loads. This outer casing then absorbs the associated loading distortions without disturbing the blade sealing system and hence maintaining the blade/casing seal and reducing performance losses. Part of the benefit of this strong design is that the -535E4 has never had an uncontained failure of any kind.

-535E4 - Cost effective advanced technology

Wide-chord fan - best FOD resistance Kevlar containment - low weight No variable stators 3-D turbine aerodynamics  Electronic engine control  Nacelle design - extensive use of composites Advanced three-shaft design Thermal barrier coatings for longer life Integrated nozzle - lower sfc and noise

The -535E4 holds the class record for length of time on wing at over 26,000 hours to first overhaul. 
The -535E4 is not limited to a select few customers with 'easy' engine operations. Many different operators have had engines on wing for over 20,000 hours. 
This reliability is reflected in engine durability. The lead -535E4 engine has achieved over 9,900 cycles on wing without being removed.

-535E4 - Benefits of strength by design

Wide-chord fan Strongest fan in the world Best FOD resistance Short, robust design Unique three-shaft design Fewest stages/fewest components Double casing design Reduces distortion Best performance retention Best engine integrity Fewest uncontained failures

The benefits of the -535E4's reliability, durability and ease of on-wing maintenance is visible in its extremely low shop visit rate. Since 1989 the engine's total shop visit rate has been stable at around 0.06/1000 EFH - an average shop visit interval of over 15,000 hours.

-535E4 - Lowest shop visit rate

Shop visit rate gives a true indication of relative maintenance costs Average time between shop visits over 12000 hours 535E4 consistently has the lowest shop visit rate in its class
- 535E4 - Longest time in wing
	Industry leading distribution High lives with many customers

International aviation organizations such as ICAO are steadily reducing the levels of permitted aircraft generated noise and emissions.
Although legislative noise limits have been constant for some years local airport authorities around the world are introducing fines based on measured aircraft noise. For a large fleet these fines can add very substantially to an airlines annual fleet operating costs. Similarly, emissions taxes and fees are now being introduced in a number of European countries.
The -535E4B powered Tu 204-120 meets all current and planned noise and emissions legislation. The power plant is the quietest and cleanest in its class ensuring that Tu 204-120 operators will be subject to the lowest levels of any environmental fines which may be applied by local authorities.

-535E4B meets all environmental legislation

Current emissions legislation	-	compliant

Post 2000 emissions legislation	-	compliant

Planned post 2007 legislation	-	compliant

Current (Stage 3) noise limits	-	13 dB margin

The Rolls-Royce powered Tu 204-120 gives a large 13dB margin to the Stage 3 noise limits.
The benefit of this to operators is not only a lower level of noise-exceedance fines but also in the ability to work within the very low night curfew noise limits imposed by many airports.
The -535E4 even allows large narrow body aircraft to take-off and land at night at very heavily restricted airports such as Washington National. This is the only power plant which allows this type of aircraft to operate fully unrestricted at this airport during the night curfew.

- 535E4B gives lowest noise levels

-535E4B gives minimum noise levels for the Tu 204-120 Tu 204-120/-535E4B has total of 13 dB margin to Stage 3 limits

-535E4 - Simple access and maintenance

All key accessories mounted on fancasefor immediate access- no engine cool down required.

The RB211-535 is 5 highly successful powerplant selected by operators around the world and used in a huge variety of operational roles and regions from European holiday charters to scheduled services in Nepal.
The engine has been selected by over 80% of large narrowbody operators.
