Rolls-Royce Trent 900 on A380 prototype

Rolls Royce Trent is a family of high-bypass turbofan engines manufactured by Rolls-Royce. All are developments of the famous RB211 with thrust ratings spanning between 53,000 and 95,000 lbf (236 to 423 kN). The name has also been used for a number of previous designs. The Trent has been one of the most successful areo engines of all time, serving on some 6 airliner series' (A330, A340, A350, A380, 777 and 787) with hundreds of airlines across the globe. The Trent is the leading engine for the new generation of widebodied aircraft (with a 45% market share) launch engine for all 3 787 variants, leading engine for 777, A330, A340-500 and A340-600 aircraft.

The first Trent - a Rolls-Royce RB.50 Trent on a test rig at Hucknall, in March 1945

"Trent" was the name originally given by Rolls-Royce to the world's first turboprop engine (right). It was based on a concept provided by Sir Frank Whittle and derived by mating a five-bladed propeller driven through a reduction gearbox onto the company's Derwent II turbojet. It first flew on an experimental Gloster Meteor aircraft in the middle 1940s. ImageMetadata File history File links Rolls-Royce_RB50_Trent_Turboprop_On_Test_Rig_At_Hucknall. ...

The designation was reused again in the 1960s for the RB203 bypass turbofan which was designed to replace the Spey. It was the first three-spool engine, forerunner of the RB211 series. It was rated at 9980 lbf (44.4 kN). The 1960s decade refers to the years from January 1, 1960 to December 31, 1969, inclusive. ... The Spey is a low-bypass turbofan engine from Rolls-Royce that has been in widespread service for over 30 years. ...


Present designation

The current Trent is the development of the three-shaft RB211 family of engines. By 1987, a variant of the RB211, the RB211-524L, had been developed to such an extent that it bore little resemblance to the original RB211, other than the three-shaft layout. Rolls-Royce decided that the 524L would be the basis of a new engine family, and so the newest Trent was born. Rolls-Royce had started naming their engines after British rivers in 1942 when the Welland went into production, and the current Trent designation revives the name after a 30-year gap. 1942 (MCMXLII) was a common year starting on Thursday (the link is to a full 1942 calendar). ... The Welland was Englands first production jet engine. ... The River Trent is one of the major rivers of England. ...


The Trent's advanced layout provides lighter weight and better performance compared to the original RB211 and other comparable competing engines. It features the wide-chord fan and single crystal high-pressure turbine blades inherited from later generations of the RB211, but with improved performance and durability.


The core turbomachinery is brand new, giving better performance, noise and pollution levels. In fact, it was seen fit to be retrofitted to the RB211-524G/HT for improved performance compared to the original 524G and 524H. The Trent's advanced layout allows it to be fully scalable to the widest range of thrust of any current generation large turbofans.

History

By the early 1990's, Rolls-Royce RB211 had 15 to 20 percent market share of the big commercial turbofans; however, GE and Pratt and Whitney were still way out in front. In the late 1980's the huge growth of ETOPS capable airliner twinjets led to demands for higher thrust rated turbofans. The option to Rolls-Royce was either to update the RB211 or risk exiting the big turbofan business; the result was, of course, that the RB211 was redeveloped into the Trent. The new Trent family spawned derivatives capable of powering a wide range of airliners. ETOPS (Extended Twin-engine OPerationS) is an acronym for an International Civil Aviation Organization (ICAO) rule permitting newer twin-engined commercial air transports to fly routes that, at some points, are further than a distance of 60 minutes flying time from an emergency or diversion airport. ...


The initial variant, Trent 600, was to power the McDonnell Douglas MD-11 with British Caledonian as its launch customer. The subsequent takeover of British Caledonian by British Airways led to its cancellation, and later as the trijet itself suffered poor sales (which one of the reasons is due to the delay of the Trent 600) the Trent 600 was put on ice. Then with the launch of Airbus A330, the Trent 700 was launched with initial customer, Cathay Pacific in March 1995. The Trent 700 was selected by many A330 customers and later went on to become the primary engine for the A330. The McDonnell Douglas MD-11 is a three-engined medium to long-range widebody airliner, with two engines mounted on underwing pylons and a third engine at the base of the vertical stabilizer. ... ‹ The template below has been proposed for deletion. ...

The Trent 800 for the Boeing 777 was also launched by Cathay Pacific. However, initially, Rolls-Royce had difficulty selling the engine. British Airways, traditionally a Rolls-Royce customer, submitted a big order for the competing General Electric GE90 engine. The breakthrough came when the company won orders from Singapore Airlines, previously a staunch Pratt & Whitney customer, for its 34 Boeing 777s; this was when sales really took off and large North American orders from American Airlines and Delta Air Lines for their 777 fleets soon followed. Since then the Trent has risen to become the market leader for the 777 and has established a reputation for being a very reliable engine with good after-sales support; British Airways returned to Rolls-Royce for its second batch of 777s.

Soon after in 1997, the Trent 500 was chosen to power the long-range quad-engined Airbus A340-500/-600 family. It entered service with Virgin Atlantic Airways' A340-600 in mid-2002 and with Air Canada's ultra-long range A340-500 in 2003. This was followed by the 70,000 to 80,000 pound (310 to 360 kN) thrust Trent 900, which was the launch engine for the Airbus A380. Virgin Atlantic Airways usually referred to as Virgin Atlantic, is one of the airlines of Richard Bransons Virgin Group, operating long-haul routes between London and North America, the Caribbean, Africa, the Middle East, Asia and Australia. ...

Trent's excellent design has also been adapted for marine and industrial applications. The huge revenue generated from sales has also propelled Rolls-Royce's market position to the second biggest engine manufacturer in the world.


Triple-spool versus Twin-spool

For a given engine cycle, there is no fundamental difference in the performance of a 3-shaft turbofan over that of the equivalent 2-shaft design. However, differences in the detail design (e.g. swept fan rotor) can yield a small specific fuel consumption advantage for either design. Specific fuel consumption, often shortened to SFC, is an engineering term that is used to describe the fuel efficiency of an engine design. ...


Although all the Trent engines in the series are generally similar in design, they have different fan and core sizes, because such a wide range of Take-off thrust is covered. The main reason for changing fan size is to keep the mean jet velocity at Take-off at a sensible level, for noise considerations. Core size changes enable the (HP) turbine rotor inlet temperature to be kept at a competitive, but feasible level. Increasing overall pressure ratio can sometimes negate the need for an increase in core size. Core size is a parameter used in aeroengine performance engineering to enable a size comparison between jet engine (e. ...


The Rolls-Royce RB211 and Trent use a triple-spool design rather than the more common twin-spool design. Although inherently more complex than a typical twin-spool design, the superiority of this design shows at higher thrust ratings by the total improvement achieved. Excellent development progress from the original RB211-22B to the current Trent engines has turned Rolls-Royce's higher thrust turbofans into performance leaders in their respective thrust rating classes, which translates into a market leadership figure of excess of 50% of all total widebody orders in 2004.


As the design overall pressure ratio of an engine cycle increases, it becomes more difficult to throttle the compression system, without encountering an instability known as compressor surge. This occurs when some of the compressor aerofoils stall (like the wings of an aircraft) causing a violent change in the direction of the airflow. However, compressor stall can be avoided, at throttled conditions, by progressively:


1) opening interstage/intercompressor blow-off valves (inefficient)


and/or


2) closing variable stators within the compressor


Most modern American civil turbofans employ a relatively high pressure ratio High Pressure (HP) Compressor with several rows of variable stators to control surge margin. However, on the RB211/Trent the HP Compressor has a modest pressure ratio and can be throttled-back surge-free, without employing HP Compressor variable geometry, thus simplifying the engine and making it lighter for a given pressure ratio.


All of the large civil turbofans being built these days feature an Intermediate Pressure Compressor (IPC), which lies between the single stage Fan and HP Compressor (HPC). The IPC supercharges the HPC, helping to raise the overall pressure ratio of the engine cycle to the very high levels employed today (i.e. greater than 40:1, typically). The American designs (e.g. PW4000, GE90, etc) are all 2-shaft engines, with the IPC mounted on the LP shaft, the mechanical speed of which is dictated by the tip speed and diameter of the fan. Fairly obviously, the higher bypass ratios (i.e. fan duct flow/core flow) used in modern civil turbofans tends to reduce the relative diameter of the attached IP compressor, causing its mean tip speed to decrease. Consequently more IPC stages are required to develop the desired IPC pressure ratio. However, on the Trent (and RB211) engines, the IPC is mounted on the IP shaft and is driven by its own (IP) Turbine. Consequently, the IP compressor can rotate faster than the fan, increasing its mean tip speed, thereby reducing the number of IP stages required for a given IPC pressure ratio. However, the RB211/Trent designs have a higher IPC pressure ratio than the American designs, because the HPC pressure ratio is modest. Nevertheless, the engine is shorter, making it lighter and more rigid. This last point is important, because it means that there is less distortion of the engine casings under 'g' loads during flight, resulting in less blade tip rubbing and, therefore, a slower in-service deterioration of component performance and specific fuel consumption. The longer, less rigid, American engines tend to deteriorate faster than the equivalent RB211/Trent designs.


When the RB211 programme originally started, it was intended that none of the compression system would require variable stators, unlike the American competition. Unfortunately, it was found that, because of the shallow working line on the IPC, at least one row of variable stators was required on the IPC, to improve its surge margin at throttled conditions. This feature has been retained throughout the RB211 and Trent series. Although the original intent was not met, Rolls-Royce eliminated the need for many rows of variable stators, with all its inherent complexity, thereby saving weight, cost and improving reliability.


Variants

Trent 500 Series

The Trent 500 family was designed to power the Airbus A340-500 and A340-600. Initially, it came in 2 thrust ratings: 53,000 and 56,000 lbf (236 to 249 kN). However, a 267kN version is installed in the A340-600HGW, a higher-performance version of the A340-600.

Trent 600 Series

The original Trent 600 was designated for the McDonnell Douglas MD-11 plane, but was never produced due to the demise of the Trent-launching Air Europe as an aftermath of the 1990 Gulf War. The current Trent 600 family is designed to power future Boeing 747 aircraft developments. It is actually a refinement of the original RB211-524L. According to Rolls Royce, it performs better than any current 747 engine. However, with the launch of the 747-8, Boeing has chosen to go with GE engines destined to power the upcoming 787.

Since that time it has become a class leader for reliability, regularly returning a basic engine dispatch reliability of 99.9% which was a factor in securing 80% of installations on 777s since the start of 1997 and over 2 million flying hours since 1996.[citation needed] ETOPS (Extended Twin-engine OPerationS) is an acronym for an International Civil Aviation Organization (ICAO) rule permitting newer twin-engined commercial air transports to fly routes that, at some points, are further than a distance of 60 minutes flying time from an emergency or diversion airport. ...


Trent 8104

Originally designed for the 777-200LR and 777-300ER (both part of the 777X project), this engine comes in two thrust ratings, 104,000 and 114,000 lbf (463 to 507 kN), and has been tested up to 117,000 lbf (520 kN).


Rolls-Royce offered the 8104 to Boeing earlier than other manufacturers. Boeing had a requirement that the participating engine developer assume a risk-sharing role on the overall 777X project. Rolls-Royce was unwilling to do so, and thus Boeing chose advanced developments of the GE90, the GE90-110B and GE90-115B. This relegated the 8104 to the role of demonstrator engine. It featured swept-back fan blades and a host of new technologies such as contra-rotating spools.


Trent 900 Series

The Trent 900 family is designed to power the Airbus A380, for which it is the launch engine. It comes in two thrust ratings, 70,000 and 76,000 lbf (311 and 338 kN) but is capable of achieving 84,000 lbf (374 kN). It features a significant amount of technology inherited from the 8104 demonstrator including its 2.95 m diameter swept-back fan. It is also the first member of the Trent family to feature a contra-rotating HP spool and uses the core of the very reliable Trent 500. It is the only A380 engine that can be transported on a Boeing 747 freighter. The Airbus A380 is a double-deck, four-engined airliner manufactured by EADS (Airbus S.A.S.) It first flew on April 27, 2005 from Toulouse in France. ...



Whereas most members of the Trent family are controlled by Goodrich FADECs, engine controllers on the Trent 900 are provided by Hamilton Sundstrand, a United Technologies (UTC) company. UTC is also the parent company of Pratt & Whitney, who, with GE Aircraft Engines, is partnering to produce the Engine Alliance GP7200, the other engine available for the A380. This kind of cooperation among competitors is prevalent in the aircraft market as it provides for risk sharing among them and diversity in source countries, a significant factor in an airlines' choice of airframe and powerplant.

Trent 1000 Series

On April 6, 2004 Boeing announced that it had selected two engine partners for the 787, Rolls-Royce and General Electric. Initially, Boeing toyed with the idea of sole sourcing the powerplant for the 787, with GE being the most likely candidate. However potential customers demanded choices and Boeing relented. For the first time in commercial aviation, both engine types will have a standard interface with the aircraft, allowing any 787 to be fitted with either a GE or Rolls-Royce engine at any time. Engine interchangeability makes the 787 a more flexible asset to airlines, allowing them to change from one manufacturer's engine to the other's in light of any future engine developments which conform more closely to their operating profile. The engine market for the 787 is estimated to be $40 billion USD over the next 25 years.

The technology found in the Trent 8104 demonstrator is used extensively. The Trent 1000 is a bleedless design, with power take-off from the intermediate-pressure spool instead of the high-pressure spool found in other members of the Trent family, to fulfill the Boeing requirements of a "more-electric" engine. A 112-inch diameter swept-back fan, with a smaller diameter hub to help maximize airflow, was specified. Bypass ratio has been increased over previous variants by suitable adjustments to the core flow. Contra-rotating the IP and HP spools improves IP turbine efficiency, while use of more monolithic parts reduces the parts count for lower maintenance costs. A tiled combustor is featured. Bleed air in jet turbines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. ...

In June 2004, the first public engine selection was made by Air New Zealand, who chose Trent for its two firm orders. The airline has options for 16 more 787s. In the largest 787 order, that of Japan's All Nippon Airways, Rolls-Royce was selected as the engine supplier on October 13, 2004. The deal is valued at $1bn (£560m) and covers 30 787-3s and 20 787-8s. The Trent 1000 is to be the launch engine on all 3 current 787 models, the -3 and -8 with ANA and the -9 with Air New Zealand. 2004 (MMIV) was a leap year starting on Thursday of the Gregorian calendar. ...

Trent 1500 Series

A Trent 500 replacement engine, known unofficially as the Trent 1500, has been proposed for the Airbus A340-500/600, to help the aircraft compete with the Boeing 777-200LR/300ER. A South African Airways A340-600 jet. ... The Boeing 777 is a family of long-range wide-body twin-engine airliners built by Boeings Commercial Airplanes division. ...


The Trent 1500 would retain the 97.4in fan diameter of the current Trent 500 engine, as well as the nacelle, but incorporate the smaller, more advanced, Trent 1000/1700 gas generator and LP turbine, suitably modified.


Trent XWB

For the original A350, Rolls-Royce offered a variant of the Trent 1000, dubbed Trent 1700. The engine would have been largely the same as the Trent 1000, but with a throttle-push to 75000lbf static thrust. Unlike the Trent 1000, the Trent 1700 would have been a conventional bleed-air engine. [7] Kawasaki would partner Rolls-Royce to develop this engine. “A350” redirects here. ... Kawasaki Heavy Industries, Ltd. ...


After a lukewarm response from the airlines, Airbus reviewed their A350 proposal. On July 17, 2006 Airbus announced that they would be offering an all-new, rather than derivative, aircraft called the A350XWB (extra wide body), with a fuselage diameter slightly greater than that of Boeing's 787, to compete with both the 787 and the 777. The Boeing 787 Dreamliner is a mid-sized wide body, twin engined passenger airliner currently under development by Boeings Commercial Airplanes unit and scheduled to enter service in May 2008. ... The Boeing 777 is a family of long-range wide-body twin-engine airliners built by Boeings Commercial Airplanes division. ...


Rolls-Royce has reached a preliminary agreement with Airbus to supply a new variant, currently called the Trent XWB (75000-95000lbf static thrust), for the Airbus A350 XWB, and it will be offered on all versions of the aircraft. Initial Entry-into-Service will be in the A350XWB-900 in 2012, at a static thrust of 87000lbf, flat-rated to ISA+25C.


Rolls-Royce have already announced an increase in the fan diameter of the Trent XWB (from the 112in of the Trent1000/Trent1700) to 118in, basically to keep the Take-off jet noise acceptable at the increased thrust level. The company will probably also have to increase the core flow, to moderate the HP turbine rotor inlet temperature. They are unlikely to increase overall pressure ratio significantly to gain core flow, because this parameter is already very high, so some increase in core size is almost inevitable. Core size is a parameter used in aeroengine performance engineering to enable a size comparison between jet engine (e. ...

General Electric has yet to confirm that it will offer a GEnx variant for the A350XWB. Flight International magazine has suggested that the GE/Pratt and Whitney Engine Alliance GP7200 may be the second engine option for the aircraft, at least on the smaller aircraft.[9] Flight International is a magazine relating to airlines, general aviation, and aerospace manufacture. ...
