In March , Boeing was to launch the longer range ERX powered by 65,—68, lbf — kN engines, with deliveries planned for The 68,—72, lbf — kN Trent was scaled from the Trent with a swept fan diameter raised to 2. The 62,—81, lbf The Trent is a version with bleed air used for the Airbus Aneo. The Trent would keep the Trent 's 2. The first engine was run on 14 June , it first flew on an Airbus A testbed on 18 February , it was certified in early , and it first flew on an A on 14 June It keeps the characteristic three-shaft layout of the Trent, with a 3.
The engine has a 9. It is the most powerful among all Trent engines. Announced on 14 July , it first ran on 27 November It made its first flight on 19 October aboard on the Aneo. Compared to the A's Trent , the 68,—72, lbf — kN engine doubles the bypass ratio to and halves emitted noise. Pressure ratio is increased to and it has a in cm fan and a bleed air system.
The current version is a turboshaft engine, producing 36 MW, using the Trent core to drive a power turbine which takes power to an electrical generator or to mechanical drives such as waterjets or propellers. Amongst others, it powers the Royal Navy 's Queen Elizabeth -class aircraft carriers. This derivative is designed for power generation and mechanical drive, much like the Marine Trent. It shares components with the Trent and First run in August as the model Trent , the Trent has achieved significant commercial success, having been selected as the launch engine for all three of the variants Trent , the A Trent and the A Trent XWB.
By June , the Trent family had completed over million hours. Singapore Airlines is currently the largest operator of Trents, with five variants in service or on order, followed by British Airways with four variants in service. The subsequent investigation found that ice released from the fuel system had accumulated on the fuel-oil heat exchanger, leading to a restriction of fuel flow to the engines.
The cause was traced to an incorrectly manufactured oil feed stub pipe. For further details refer to the article on the Trent The test phase ended by summer Hispano Suiza's new accessory gearbox, Goodrich 's new distributed control system, and Techspace Aero's new oil system were also fitted. After flights test in of CTi fan blades with a titanium leading edge and carbon casing, they had indoor and outdoor tests in , including crosswind , noise and tip clearance studies, flutter mapping, performance and icing conditions trials.
Rolls-Royce will ground test in its ALPS demonstrator: a Trent fitted with composite fan blades and case, including bird strike trials. On 26 February , Rolls-Royce detailed its Trent future developments. In previous Trents, the HP spool was similar and the engine grew by expanding the intermediate pressure spool work.
The Advance reverses this trend and the load is shifted towards the high pressure spool, with a greater pressure ratio, up to 10 stages compressor compared to 6 on the Trent XWB and a two-stage turbine against the current single-stage, while the IP compressor will shrink from the 8 stages of today's XWB to 4 and the IP turbine will be single instead of two stages. The Advance3 ground-based demonstrator includes lean burn , run before on a Trent architecture only; ceramic matrix composite CMC for turbine high-temperature capability in the first stage seal segments and cast-bond first stage vanes; hybrid ball bearings with ceramic rollers running on metallic races, required to manage high load environments inside smaller cores.
The twin fuel-distribution system in the lean-burn combustor adds complexity by doubling the pipework and with a sophisticated control and switching system but should improve fuel consumption and lower NOx emissions.
Hybrid ceramic bearings are newly configured to deal with loading changes and will cope with higher temperatures. More variable vanes in one IP and four HP compressor stages will be optimised for constant changes through the flight envelope. An air pipe is produced by additive manufacturing and prototype components come from new suppliers.
The Advance3 will survey bearing load, water ingestion, noise sources and their mitigation, heat and combustor rumble while blade-tip, internal clearances and adaptive control operation are radiographed in-motion to verify the thermo-mechanical modelling.
The Boeing New Midsize Airplane needs falls in its thrust range. Advanced cooled metallic components and ceramic matrix composite parts will be tested in a late demonstrator based on a Trent XWB within the high temperature turbine technology HT3 initiative. Noise testing will follow on an outside rig, then flight tests in the next couple of years after The Ultrafan keeps the Advance core, but also contains a geared turbofan architecture with variable-pitch fan blades.
As the fan will vary pitch to be optimised for each flight phase, it won't need a thrust reverser. Rolls-Royce will use carbon composite fan blades instead of its usual hollow titanium blades, and along with new material adoption will save kg lb per engine. The variable pitch fan will facilitate low pressure ratio fan operability.
The ratio of the initial test gear will approach and thrust could be up to kN , lbf. In partnership with Liebherr , the 75, kW , hp UltraFan gearbox was first run in October The gearbox went through high-power tests in May The first gearbox was disassembled for evaluation, confirming the component's performance predictions. A complete demonstrator will be built in a few years from The demonstrator will generate — kN 70,—80, lbf of thrust, exploiting current testing on the Advance 3 and the 52, kW 70, hp gearbox.
Its fan diameter could be up to 3. Higher bypass and lower fan pressure ratio induce low-speed fan instability remedied by variable-pitch blades instead of a variable area jet nozzle. Along with eliminating the thrust reverser, a short slim nacelle would be lighter and less draggy , but in reverse-thrust the flow would be distorted, having to be turned around the nozzle into the bypass duct , and then partly reversed again into the intermediate compressor.
The large fan could lead to gull-wing airframes. The mm 2 ft 7 in diameter planetary gearbox has five planet gears, is sized to power — kN 25,—, lbf turbofans and amassed over hours of run time by early In February , potential introduction was delayed to , to re-engine current aircraft, after full-scale ground tests in A — kW — hp integrated starter-generator on the shaft cold end would allow a smaller accessory drive.
By February , Rolls-Royce was manufacturing the cm in diameter carbon fibre fan blades in Bristol, UK, saving with the composite fan case up to kg 1, lb on a twinjet.

However, as the A's design weight increased, it became clear that more thrust would be required and Rolls proposed the Trent , the first member of the Trent series. In April Cathay Pacific became the first customer to specify an Airbus aircraft powered by Rolls-Royce engines when it ordered ten As powered by the Trent The following month TWA followed suit with an order for twenty As. The Trent first ran in August , and certification was achieved in January Rolls-Royce claim that the Trent is the quietest and cleanest engine available on the A Emirates and Cathay Pacific are the largest operators, each with 29 Trent powered As.
Sales of the engine are still strong: Rolls received orders for of the type during the Paris Air Show in June The Trent family powers the Airbus A It comes in 2 thrust ratings, 67, and 71, lbf to kN. It first entered service on Cathay Pacific As in March, At the same time Boeing were investigating an enlarged development of its model dubbed the X, for which Rolls-Royce proposed the Trent By Boeing abandoned its planned X and instead decided to launch a new, larger aircraft family designated with a thrust requirement of 80, lbf or more.
The Trent 's Rolls brought in Kawasaki Heavy Industries and Ishikawajima-Harima Heavy Industries as risk and revenue sharing partners who between them took an 11 per cent stake in the Trent and programmes. Testing of the Trent began in September , and certification was achieved in January British Airways announced in September that it was returning to Rolls-Royce for its second batch of s, and did so again in April The Trent family powers the Boeing It is available on the , ER, and variants, with thrust ratings spanning 75, to 95, lbf to kN.
No airline operates the engine with greater than 93,lbf thrust however, as it has yet to be certified to any higher level for commercial operations. The engine is one of the lightest in its class; a Trent-powered Boeing weighs up to 3. In Boeing proposed new longer range variants of the X; taking advantage of the Trent 's growth capability, Rolls-Royce designed and built an improved engine designated Trent which was later scaled upwards to the even larger However, Boeing required that the participating engine developer assume a risk-sharing role on the overall X project.
This relegated the to the role of demonstrator engine. Originally designed for the LR and ER both part of the X project , this engine comes in two thrust ratings, , and , lbf to kN , and has been tested up to , lbf kN. As Boeing's thrust requirements increased, Rolls-Royce began developing the , lbf which was to be an enlarged version of the , with a inch 3.
It featured swept-back fan blades and a host of new technologies such as contra-rotating spools. The was never built, as Boeing signed a contract with General Electric to be the sole supplier of engines for the X aircraft, owing to GEs willingness to risk-share on the airframe part of the project, and sales of the aircraft to GECAS.
In April Airbus signed an agreement with General Electric to develop a suitable engine, but decided not to proceed when GE demanded an exclusivity deal on the A The Trent first ran in May and achieved certification in December A total of 15 customers have placed firm orders for over aircraft. The Trent powers the Airbus A and A The Trent has the same wide-chord fan as the Trent , together with a core scaled from the Trent In the early s Airbus had begun development of a larger successor to the Boeing , an aircraft designated A3XX, which was later to be formally launched as the A By its definition had progressed to the extent that Rolls-Royce was able to announce that it would develop the Trent to power the A In October , the Trent became the A's launch engine when Singapore Airlines specified the engine for its order for 10 As; this was quickly followed by Qantas in February Rolls-Royce has seven risk and revenue sharing partners on the Trent Industria de Turbo Propulsores low pressure turbine , Hamilton Sundstrand electronic engine controls , Avio S.
It comes in two thrust ratings, 70, and 76, lbf and kN but is capable of achieving 84, lbf kN. It features a significant amount of technology inherited from the demonstrator including its 2. 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 It is the only A engine that can be transported on a Boeing freighter.
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. In July Rolls-Royce signed an agreement with Boeing to offer the Trent engine on developments of and aircraft.
The variant was to be a new longer-range version of the Boeing ER to be powered by the Trent and Engine Alliance GP, although in the end this aircraft was never launched. When Boeing finally launched the in it announced that the General Electric GEnx would be the only engine available for the On April 6, Boeing announced that it had selected two engine partners for its new Rolls-Royce and General Electric. Initially, Boeing toyed with the idea of sole sourcing the powerplant for the , 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 to be fitted with either a GE or Rolls-Royce engine at any time. As with earlier variants of the Trent family, Rolls partnered with risk and revenue sharing partners on the Trent programme. This time there were six partners: Kawasaki Heavy Industries intermediate compressor module , Mitsubishi Heavy Industries combustor and low pressure turbine blades , Industria de Turbo Propulsores low pressure turbine , Carlton Forge Works fan case , Hamilton Sundstrand gearbox and Goodrich Corporation engine control system.
Between them these partners have a 35 per cent stake in the programme. In June , the first public engine selection was made by Air New Zealand who chose the Trent for its two firm orders. Entry into service is currently scheduled for December following Boeing's announcement in October that deliveries would be delayed by six months.
The technology found in the Trent demonstrator is used extensively. The Trent 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. The Rolls-Royce Trent is a high-bypass turbofan produced by Rolls-Royce plc , one of the engine options for the early Boeing variants.
Launched in September , it first ran in September , was granted EASA certification on 27 January , and entered service in The Trent has the Trent family three shaft architecture, with a cm in fan. With a 6. By , as Boeing was studying the enlarged X , Rolls-Royce was proposing its Trent engine with a larger in cm fan driven by a new, bigger LP turbine, a modified IP compressor and no exhaust mixer. It would attain 75, to 85, lbf to kN , to be certified in early for a mid introduction, with growth potential to 90,—95, lbf — kN with a new HP core.
Certification was applied for on 2 April British Airways announced in September that it was returning to Rolls-Royce for its second batch of s, and did so again in April The last Trent powered was delivered in It incorporates technology from Trent and Trent XWB engines including elliptical leading edges on intermediate- and high-pressure compressor blades.
Rolls-Royce claims that it provides a 0. The Trent is an axial flow , high bypass turbofan with three coaxial shafts. The fan is driven by a 5-stage axial LP turbine rpm , the 8-stage IP compressor rpm and the 6-stage HP compressor rpm are each powered by a single stage turbine. It has an annular combustor with 24 fuel nozzles and is controlled by an EEC. The engine has a 6. Rolls-Royce claims it is the lightest Boeing engine, citing a 8, lb 3.
The subsequent investigation found that ice released from the fuel system had accumulated on the fuel-oil heat exchanger , leading to a restriction of fuel flow to the engines. Data from EASA . From Wikipedia, the free encyclopedia.
