Garuda gets first Trent-powered Airbus A300-300s<\/p>\n
The first of Garuda's six Airbus A330-300 planes, powered by
\nRolls-Royce Trent 700 engines, is scheduled to arrive in Jakarta
\ntoday from Airbus Industrie in Toulouse, France. The Jakarta Post
\nsent its reporter Akmal Syams on an Indonesian media tour of
\nRolls-Royce's base in Derby, England. He wrote the following
\narticles.<\/p>\n
DERBY, England (JP): Passengers bound for Hong Kong, Taipei,
\nJapan, Guangzhou and Australia from Indonesia will soon be able
\nto fly Garuda Indonesia's newest jetliners powered by one of the
\nworld's most powerful and environmentally friendly aircraft
\nengines, the Rolls-Royce Trent 700.<\/p>\n
Today's delivery of Garuda's first Trent 700-powered Airbus
\nA330-300 aircraft is the latest chapter in Rolls-Royce's and the
\nIndonesian national flag carrier's relationship which began more
\nthan a quarter of a century ago.<\/p>\n
The British engine maker first sold Garuda Spey engines for
\nits fleet of Fokker F28 regional jets.<\/p>\n
Garuda's latest purchase are Trent 700s from Rolls-Royce's
\nnewest and strongest turbofan engine series. The first of the
\nseries went into service in March 1995 for Cathay Pacific.<\/p>\n
David Wick, the senior vice president for sales and marketing
\nof Rolls-Royce Commercial Aero Engines Limited, told a group of
\nIndonesian journalists here recently that development of the
\nTrent engine began in 1988 and the engine was first operated in
\nJuly 1992.<\/p>\n
\"It went through a more comprehensive and intensive set of
\ncertification tests than any previous Rolls-Royce engine. It came
\nthrough punishing tests simulating the worst imaginable hail and
\nrain storms, and proved its ability to survive bird strike by
\nflocks and large single birds, and to contain a detached fan
\nblade.\"<\/p>\n
\"All these were successfully completed, and were backed by
\nendurance testing at extreme operational conditions --
\naccelerating thousands of hours of \"service\" experience,\" Wick
\nsaid.<\/p>\n
Certificates<\/p>\n
The Trent 700 was certificated at 72,000lb thrust in December
\n1993 by Europe's Joint Airworthiness Authorities and soon after
\nby the United States' Federal Aviation Administration. The engine
\nwas first tested in an A330 at Airbus Industrie's flight test
\ncenter in Toulouse, France, in January 1994. A year later, the
\nengine-airframe combination was certificated for airlines.
\nDevelopment of the Trent 700's big brother, the Trent 800,
\nfollowed about a year later: it was tested in September 1993,
\ncertificated in January 1995, debuted in the Boeing 777 in May
\n1995 and began service operations with Thai Airways International
\nin March this year.<\/p>\n
Trent marketing head James E. Sheard said Rolls-Royce
\ndeveloped the Trent series to meet increasing demand for more
\neconomical and environmentally-friendly engines: \"So, the Trent
\nis, actually, Rolls-Royce's answer to the new market
\ndevelopment.\"<\/p>\n
Airlines' needs were paramount when leading aircraft makers
\nbegan designing a new generation of wide-bodied airplanes.<\/p>\n
\"With the aircraft needing to carry up to 350 passengers, the
\nengines must be more powerful than ever before, and more
\nreliable, quieter and fuel efficient,\" Sheard said.<\/p>\n
Compared to its competitors, Trents had the shortest take-off
\nfield length, best payload range, lowest operating cost (lowest
\nfuel burn) and were the quietest (large margin to emission
\nregulations), he said.<\/p>\n
Based on the International Civil Aviation Organization (ICAO)
\ncommittee for aviation and environmental protection's emission
\nrules, the Trent 700 makes less smoke than the PW4164 and CF6-
\n80E1A2.<\/p>\n
For take-off performance, Trent 800 is 200 feet better than
\nPW4090 and GE90-90B.<\/p>\n
Sheard said the Trent 700 and 800 had secured a large share of
\nthe wide-body twin-jet market.<\/p>\n
Garuda Indonesia, Cathay Pacific, Thai Airways International,
\nDragonair, Singapore Airlines, Malaysia Airlines, Singapore
\nAircraft Leasing Enterprise, GulfAir, Emirates, TWA and
\nInternational Lease Finance Corporation are using Trent engines
\nin their aircraft. They have ordered US$5 billion worth of
\nengines for 200 airplanes. A Trent 700 engine costs about $11
\nmillion.<\/p>\n
Many of the customers are from the fast-growing Asia-Pacific
\nmarket, where Trent has had remarkable success supplying engines
\nfor almost half of the Boeing 777\/Airbus 330 aircraft ordered
\nthere. It has a 35 percent of the same market worldwide.<\/p>\n
Dr. Robin Singleton, the head of Rolls-Royce International's
\nJakarta office, told The Jakarta Post that Rolls-Royce was
\npromoting Trent 800 engines to Garuda Indonesia.<\/p>\n
\"We are currently briefing Garuda about the suitability of the
\nTrent 800 for the Boeing 777s which Garuda has ordered,\" he said.<\/p>\n
Garuda has ordered six long-range 777-200s as part of a US$1.6
\nbillion order for 23 Boeing jets to be delivered between 1997 and
\n2002.<\/p>\n
Rolls-Royce, Pratt and Whitney and General Electric produce
\nengines for the B777s. Garuda has not yet decided which company's
\nengines it will use for the B777s.<\/p>\n
Three-shafts<\/p>\n
The Trent has built on the proven three-shaft RB211 series,
\nproduced by a BMW-Rolls-Royce joint venture. It has retained key
\nreliability features such as hollow titanium wide-chord fan
\nblades -- the accepted industry leader at coping with foreign
\nobject ingestion -- and has added latest technology such as a 3-D
\naerodynamic design, new materials and coatings and advanced
\ncooling.<\/p>\n
Dr. G. A. Fitzpatrick, Rolls-Royce's Aerospace Group project
\nmanager, said the three-shaft design lets its low, intermediate
\nand high pressure systems run at their optimum aerodynamic
\nspeeds, giving the engine flexibility and economy and making it
\nshorter, more robust and lighter than other engines.<\/p>\n
\"As for an example, a pair of Trents on the Boeing 777 is up
\nto three tons lighter than competing engines,\" he said.<\/p>\n
The hollow titanium wide-chord fan blades, produced with
\nstate-of-the-art technology, are the pride of Rolls-Royce. The
\nfan provides about 75 percent of engine take-off thrust and must
\nresist the fatigue stresses of flying.<\/p>\n
The company has developed unique manufacturing technologies
\nfor hollow titanium fabrications with lightweight internal cores.
\nThe first generation of wide chord fan blades with honeycomb
\ncores was in service in 1984. The second generation components
\nwith super-plastic formed cores went into service last year.<\/p>\n
Rolls-Royce has invested 30 million pounds (about $49.8
\nmillion) in its manufacturing plant in Barnoldswick, Colne, in
\nLancashire. The plant produces 25 wide-chord fan blades a month.<\/p>\n
New generation<\/p>\n
Computer-based design and analysis have accelerated engine
\ndevelopment, and computer modeling can be used by many
\ndepartments in Rolls-Royce.<\/p>\n
The Trent's creation has brought simultaneous engineering a
\nlarge step closer.<\/p>\n
This will boost development of the Trent 900, an engine option
\nfor Boeing 747-500X\/600X and A3XX four-engine high-capacity
\naircraft which are due to start flying early next decade.<\/p>\n
Based on the Trent 800, the 900 is in the 75,000-80,000lb
\nthrust class. It will incorporate a scaled fan and modified
\nturbine components, giving a higher by-pass ratio and more fuel
\nefficiency. It is expected to meet and beat all current and
\nanticipated noise and emissions regulations.<\/p>\n
Its proven pedigree will give it a head start on its
\ncompetitors for the \"super jumbos\" of the next millennium.<\/p>\n
Award<\/p>\n
The state-of-the-art Trent engine has been recognized by the
\nRoyal Academy of Engineering MacRobert Award Trust, an
\nindependent body based in London. The Trent won this year's
\nMacRobert Award, which consists of a gold medal and a 50,000
\npound ($83,298) prize. The award was presented by His Royal
\nHighness The Duke of Edinburgh to five engineers representing
\nRolls-Royce at Buckingham Palace late last month.<\/p>\n
The trust has provided annual awards to individuals or
\nengineering teams for outstanding achievements since 1969.<\/p>\n
This is the third time that Rolls-Royce has won the MacRobert
\nAward, Britain's premier award for engineering innovation. The
\ncompany won the award for the Harrier jump-jet's Pegassus engine
\nin 1969, and for a high-energy X-ray inspection system used
\nduring engine testing in 1985.<\/p>",
