Airbus Industrie, a consortium of European aircraft manufacturer which provided the first serious competition in the U.S. in its original widebody, twin-engined A-300, was quickly concluded that its success can be attained only in an expanded line product with the ability to carry some cargo and range of needs. Subsequently added to the “family” of airliners is therefore the smaller-capacity, medium-to long-range range, widebody A-310 and the smaller still-capacity, range, narrow body A-320 . To complete it, however, a long-range widebody, incorporating new technology, is required to replace the first generation, fuel-thirsty, have no economic Boeing 707s and McDonnell-Douglas DC-8s.
Market study, however, indicates the need for two different aircraft. The first of these, temporarily designated “B9,” is for a moderate range, two motor design intended for high capacity transcontinental, DC-10 as the route, and initially was conceived as a more large A-300 with a stretched fuselage, the existing wings, and the most powerful turbofans then available. So configured, it would have required 25-percent lower than the comparable gasoline, tri-motor DC-10.
The second, the “B11″ is a quad-motor design continents which sparked the beginning of the project’s.
Cost for two such aircraft, however, prevents, and a wing design, aerodynamically and structurally to support both two and four pylon-mounted engine, became the main commonality between the two and the other economic solution to the joint launch of both.
To see the difference between its narrow and broad line of body products, Airbus Industrie redesignated the design of the study “thank” prefix to indicate their “twin aisle” configuration. The “B9″ is so re-identified as “TA9″ and “B11″ is branded the “TA11.
Powered by CFM56 turbofans, developed between 27,000 and 30,000 pounds of thrust, they have changed through various iterations, with the number reflecting engine intended mission length. Sa 1982, for example, TA9, featuring a 27.9-foot fuselage than the original A-300, had accommodated 410 single-class passengers to the main deck and five pallets with forward handle 14 and LD – 3 the container hold in the aft lower deck. Included in the amount of technological advancement introduced in A-320, however, the combined project was featured TA9/TA11 its cockpit, side stick control, and fly-by-wire, or electronic signaling, upon actuation of flight, by of 1985, mated to a variable-camber wing to increase lift.
By January 27 of next year, the Airbus Industrie supervisory Board redesignated the design of A-330 and A-340, corresponding to the original TA9 and TA11 model number, and finalized their detailed technical definition then envisioned the launch customer Lufthansa and Swissair. Requirements for route, they showed greater interest in quad-motor version than twins.
A brief collaboration navigate-McDonnell Douglas, where a single design, designated AM-300 and included the A-330 wing and the MD-11’s fuselage, has quickly waned because Airbus Industrie refused to consider McDonnell-Douglas’s tri-jet configuration. The MD-11 is resultantly become the A-340’s competitor, since both are intended for the same market.
The Airbus Industrie’s design, entering a second major evolution, can offer significantly improved performance when it traded the original expected CFM56 engines in the International Aero Engines (?æ) V2500-3 Superfan which, the cutting edge of technology , has included an initial, variable-black fans; almost nine feet diameter, a 17.5-to-1 bypass ratio and have made 32,000 pounds of thrust. Early estimates are promised a 15 percent fuel savings, though they later reduced by about a third.
The aircraft then envisioned, the A-340-200, had accommodated 262 passengers and had a maximum range of 7,850 miles. The second version, featuring a 14-foot fuselage reach for a 295-passenger complement, were offered a reduced-range capabilities, the 7000 miles, and was appointed A-340-300.
The wall program, however, when suddenly crumbed International Aero Engines Superfan suddenly canceled development for technology insurmountable obstacles of his very advanced design, and Airbus Industrie are forcibly entered his third major evolution when it is renegotiated sa CFM International to power the engine. Not able to meet the performance specifications, Airbus is almost back to pre-Superfan configuration, and only on considerable design change may aircraft even approach its capacity intermediate repetitions.
CFM International to redesign itself in major CFM56 engine, increasing its diameter fan to produce more thrust, and it resulted in the CFM56-5C1 came, while Airbus has increased the average wingspan A-330/A- 340 183.9-192.2 feet, replacing its standard tips 9.6-foot winglets. Although the changes, including a 17,600-pound maximum weight increase of 542,300 pounds plus, are significantly improved the performance given in the first, CFM56-powered aircraft, range is nevertheless broken within Superfan version, the 7700 miles for A-340-200 and 6850 miles long -300.
However, Airbus Industrie had formally announced the launch of the A-330 and A-340 program June 5, 1987 that the cost development is reduced by some half-billion dollars for the Airframe wing type and commonality, yet at the same time is able to serve the differing needs plane market with the same platform. One hundred thirty orders were received at this time, which is 41 for twin-engined A-330s and 89 are for a four-motor-340s.
The wings, the key to both, was built by British Aerospace in the UK and is Europe’s hitherto most ambitious, with the largest span (more than 197 feet), the greatest sweepback (30 degrees), and the highest aspect ratio (of 9.3 to facilitate the long-range cruise speed). Although the A-340 is designed to carry 20 percent more cargo and fuel than its twin-engined counterpart, wing-bending moments exerted on fuselage enabled it to accommodate either two or four pylon-mounted turbofans. Winglets, covering some 90-percent of the wingtip chord and leaning out a 42.5-degree angle, has reduced fuel burn by 1.5 percent by Harnessing the tip-vortex created where the drag – creating pressure differentials are forcibly remixed.
Aerospatiale, one of Airbus Industrie member agreement, constructed a $ 411 million, 124-acre final assembly plant in Colomiers, adjacent to existing facilities in Toulouse-Blagnac Airport in France, allowing up to seven aircraft per months to complete after their subassemblies and components are FLOWN from several European sites
.
The first aircraft, an A-340-300, was rolled outside to October 4, 1991, during which well-A-330 and a 340 order is totaled 250, and first quad-motor Airbus Industrie’s , long-range, pure-jet airliner, with 440,530-pound gross weight, leaving the land for the first time 21 days later on October 25. Attaining an altitude of 40,000 feet, to complete a successful four hours, 47-minute maiden flight, and his test pilots have expressed that it is holding such as A-320 to fly to-by-wire flight controls are based.
The A-340 to 300, with a 208.11-foot total length, which featured a 197.10-foot wingspan and a 3892.2 square foot area. Identical to A-330 with wings except for external strengthening and a gap between fourth and fifth leading edge slat to serve outboard engine attachment pylon, fly himself is featured full-span slats, The following FLAPS side, two outboard ailerons, and five outboard spoilers, all operating off of three independent hydraulic systems. Eleron droop wing lift increased. The single rudder is directly linked to the rudder pedals flight deck. The undercarriage, consists of a twin-wheel, forward-retracting nose gear; quad two-wheel, the mind-retracting main bogies and a twin-wheel, behind-retracting gear centerline; is still uncertain even weight distribution, especially in weaker concrete surface.
The aircraft, exit-limited to 440 passengers in a single-class, nine-abreast, 31-inch internal configuration can alternatively accommodate 335 dual-class passengers on a 30 business and 305 economy-class repairs or 295 three-class passengers on a 18-first class, 81 business-class and 196 economy-class configuration, and all the different densities.
The foreshortened A-340-200, made its acceptance of the flight the following year on April 1, 1992, has featured an eight-frame fuselage reduction, resulting in a 194-foot, 11 – ¼ inches total length and 262 allowing three – class passenger on a 18/74/170-arrangement or 303 dual-class passengers sit in a 30-first class and 273 economy-class configuration of relief.
After a 2400-hour, 750-flight test program, which had entailed a six-340-200 and -300 airframes, was completed on December 22, 1992, the long-range, quad within the motor design Airbus Industrie has received its joint European Aviation Authorities (Jaa) type certification on the same day, and the U.S. Federal Aviation Administration (FAA) type approval the following year, in May 27, 1993.
Lufthansa, the launch customer of the type, taken delivery of its first A-340, a -200 configured for 228 passengers, and it inaugurated service February 2, 1993 between Frankfurt and New York, achieving a 30 fuel-percent reduction of over of the DC-10-30 it replaced. It is progressively introduced to transatlantic routes in many of its other U.S. gateways, among them Atlanta, Boston, Dallas, Houston, Newark and Washington.
Air France has inaugurated the first stretched A-340-300 services the following month in Paris-Washington route, replacing Boeing 747s.
Final assembly of the first twin-engined A-330, which is most closely mirrored the A-340-300, began in February of 1992 sa tenth aircraft from the combined line A-330/A-340 production. It appears that without the external strengthening wings and fuselage centerline undercarriage Bogie, the aircraft, powered by two General Electric CF6-80E1 turbofans, taken to heaven for the first time on November 2 in 400,880-pound gross weight, attaining a 41,000-foot ceiling and completing a successful five-hour, 15-minute flight. Because of experience gained in its quad-motor counterpart, Airbus Industrie will develop its certification program only half the traditional time. On October 21 next year, it became the first commercial design to simultaneously receive and Jaa FAA type certification, and FAA also received cross-crew qualification for the A-320, A-330, and A -340.
Service inaugurated on January 17, 1994 with Air Inter / Europe Air France Paris / Orly-Marseilles French domestic routes, the type, appointed by the A-330-300, also had the first FLOWN sa Pratt and Whitney PW4168 engines on October 14, 1993 and lists Royce Trent 700s on 31 January 1994.
Until now despite the strategy of Airbus Industrie offers a progressively larger-capacity, higher gross weight version, poor sales of A-330 twin, including uniform plane demand for a slightly lower -ability, the-range version and persistent inroads of its target market through the Boeing 767-300ER, is strongly advocated the need for a reverse approach.
A new version, the A-330 to 200 with ten-fuselage frame and reducing the 193.7-foot total length, is by the Airbus Industrie supervisory Board on November 24, 1995. The aircraft, which will require $ 450 million program development, structural change is for the weight range and, as a DC-10 and L-1011 return, was a live 767 competitor, who offers a nine percent lower direct operating costs than the Boeing opponent, yet achieving 6.400-mile range. Improved engine efficiency, coupled with the successful extended twin-engine operations, has rendered it an economic transatlantic airliner connect Europe all but U.S. West Coast cities.
The new version, with six feet forward and four feet aft fuselage reduction, featured a powered wing designed for long-range sobra A-340-300E, and a 3.5-foot taller vertical tails to pay for the moment the shorter fuselage-arm’s. A five-degree increase in rudder travel, to / – 35 degrees, is also introduced. Accommodation is entailed 253 tri-class or 293 dual-class passengers. The greatest strength’s version, however, the fuel-increase capacity to 36,700 U.S. gallons, attained by using a former dry center section fuel tank, resulting in a crucial increase range.
First flying in August 13, 1996, the A-330-200, powered by General Electric CF6-80E1A4 turbofans, has attracted 85 orders from eight carriers at this time, along with Asiana, Austrian Airlines, Emirates, International Lease Finance (ILFC), Sabena and Swissair. Such as A-330-200, later it was certified that there are three types of power plant.
Although A-330-100 and -500 studies eventually led to the all-new A-350 twin, A-340 program developments occurred in reverse, or more traditional, direction. Search offers a higher-capacity, replacement Boeing 747, Airbus Industrie are starting to expect a 12-frame fuselage reach of existing A-340-300-340 designated A-400X , powered by the existing turbofans, but the plane had too interest dictated a larger aircraft.
The final version, the A-340-600, has featured a 19.3-foot forward and aft 10.6-foot, or ill-20-frame, fuselage reach, resulting in the longest airliner in the world, with a 245.11-foot total length. In fact, the aero-elasticity, resulting from time to time, in-flight bending frequency, has necessitated the installation of sensors to maximum rate fuselage and wings to provide feedback and elevator counter-movement, restricting the bending course in 2 – 3 Hz.
An extended wingspan, attained by a tapered insert, has made a 20-percent increase in area 4703.8 square feet, a 40-percent increase in lift, and a 38-percent increase, of 11,760 U.S. gallons, of gasoline. Sweepback had also increased, 30-31.5 degrees, with equal increase in the angle of the winglets.
The fuselage moment-arm is enabled lateral axis controlled with almost two feet shorter vertical tail installed the A-330, but a 38-percent larger horizontal, all-moving tail surface mixture is required to maintain effective control over the pitch.
Weight distribution is maintained in a quad-wheel, centerline forward-retracting undercarriage Bogie, increasing accommodation aft hold United by two.
The $ 2.9 billion program, launched in December 8, 1997 with 16 commitments from Virgin Atlantic, led to his first flight four years later on 23 April 2001. Powered by four lists Royce Trent 556 engines, the aircraft was airborne for five hours, 22 minutes.
For carriers of placing greater emphasis on the range than the cargo, Airbus Industrie has offered, parallel to the A-340-600, a low-capacity, ultra long range version designated the A-340-500 . Featuring a 1.9-foot forward and three-foot aft fuselage plug on basic A-340-300, the 313 triple-class passenger aircraft, six frame longer than the original -300 series or 14 frames shorter than -600, is a 221.6-foot total length and working with -600 ’s wing. First flight on February 11, 2002 and certified in 11 months December 3, received the first order from Air Canada, Emirates, ILFC and Singapore Airlines. Its extreme range, the longest of any commercial pure-jet airliner, appeared several flight records. On February 3, 2004, for example, an A-340-500 operated by Singapore Airlines had FLOWN the 7609 nautical miles between the Philippines and Los Angeles 14 hours, 42 minutes, while the same aircraft is spanned The 8963-mile distance from New York five months to June 28 to 18 hours, 18 minutes.
Having utilized a single Airframe-and-wing platform, Airbus Industrie eventually succeeds in designing its first high capacity, long-range airliner, resulting in two twin-engined and four quad-motor version where is the versatility to change the old-generation 707s, DC-8s, DC-10s, L-1011s, and 747s of different types of routes, and the end of 2008, is had amassed a collective 1400 sales of more than 100 worldwide operators. His original goal of completing its Airbus “family” of aircraft is then fulfilled.
