Boeing 787

Boeing 787 Dreamliner

Model 787 is Boeing's newest aircraft type. It is a mid-size widebody aircraft for medium to long ranges and intended as the successor of the Boeing 767. It competes with the Airbus A330 and A350.

In March 2001 Boeing presented the Sonic Cruiser, a futuristic looking widebody airliner with canard-wings, a delta wing, rear-mounted engines and two horizontal fins. The Sonic Cruiser was intended to fly at speeds close to Mach 1, that is 15 to 20 per cent faster than current jetliners do. The Sonic Cruiser offered accommodation to 200 to 250 passengers and could fly 11,100 to 16,650 km (6,000 to 9,000 nm) at an altitude of around 15,000 m (45,000 ft). Boeing had worked on the design since 1999.

After the first sensation the airlines soon became less enthusiastic. There were uncertainties about the cost of the new technologies involved and about the relatively high fuel burn of flying at high speeds compared to what a new conventional airliner would use. After the terrorist assaults of September 11, 2001, most airlines were in a bad financial shape and lost interest in the Sonic Cruiser. In December 2002 Boeing shelved the project and focused its attention on a conventional-looking 250-seater, the 7E7. The E stood for 'Efficient' and Boeing's intention was to build a very fuel-efficient, silent and clean aircraft, with maximum use of new technology. The aircraft would become a replacement for the 767. Later the 7E7 was redesignated Boeing 787 and named 'Dreamliner'.

50 per cent composites

The Boeing 787 is an all-new airplane and Boeing has incorporated lots of new technology in the design. About 50 per cent of the primary structure, including the fuselage and wing, are built of composite materials, like carbon fibre reinforced plastics. For comparison: the Boeing 777 incorporates 12 per cent composites in the primary structure. The use of composites makes it possible to manufacture large one-piece fuselage sections, which eliminate thousands of aluminum sheets and ten-thousands of fasteners. The General Electric GEnx or Rolls-Royce Trent 1000 turbofans burn about 8 per cent less fuel than the engines of earlier widebody aircraft. So-called chevrons on the engine nacelles help to reduce noise.

Another feature of the 787 are 'health-monitoring systems', which monitor the technical condition of the airplane and report maintenance information to computer systems on the ground. Boeing claims that these systems help to reduce maintenance costs by 30 per cent compared to current airliners. Passengers on the 787 enjoy windows which are larger than usual on today's airliners.

Three versions

Boeing initially wanted to build three versions of the Dreamliner. The 787-8 for 210 to 250 passengers and a range of 15,200 km (8,200 nm), the stretched 787-9 seating 250 to 290 passengers and a range of up to 15,750 km (8,500 nm) and the 787-3 with 290-330 seats, optimized for much shorter flights of 4,650 up to 5,650 (2,500 to 3,050 nm). Because the airlines didn't show much interest in the latter version - JAL and ANA were the only customers - Boeing cancelled the 787-3. Under study is a stretched 787-10, which will have about the same capacity as the 777-200.

Parts of the Boeing 787 are constructed by suppliers at sites far from Seattle. To fly large parts of the aircraft to the final assembly line, including fuselage sections and wings, Boeing developed a special version of the Boeing 747, the 747-400LCF (Large Cargo Freighter), named 'Dreamlifter'.

The first flight of the Boeing 787 was initially scheduled for August 2007, but Boeing had to admit delays due to production problems several times. One problem is a shortage of fasteners in the industry and another complication is that sub-assemblies delivered by partners often are not complete so that a lot of unexpected extra work is necessary on the Everett production line. In the end the first flight took place on 15 December 2009, more than two years behind the original schedule. The US and European aviation authorities, FAA and EASA, certified the 787 on August 26, 2011.

The first delivery to All Nippon Airways (ANA) was orignally planned for May 2008, but the first production Dreamliner was delivered on 26 September 2011, more than three years later. During the first years the production will be substantially lower than originally planned. To ramp up production Boeing has opened a second assembly line for the 787 in North Charleston (South Carolina), where labor unions are less powerful than in and around Seattle in the State of Washington.

Anyhow, the Boeing 787 had a spectacular sales start. Boeing received more orders for the type than for any of its airliners in such an early state of the program. At the moment of the official roll-out (on 07-08-2007 = 7-8-7) the orderbook comprised orders for more than 600 aircraft. In mid 2008 Boeing had orders for about 900 aircraft, but since then some airlines cancelled orders. In June 2011 Boeing had 827 orders in the books from 59 customers. Among the first buyers of the Dreamliner were: All Nippon Airways, Air New Zealand, Blue Panorama (Italy), First Choice Airlines (UK), Japan Airlines (JAL), Northwest Airlines, Air Canada, Korean Air, a combination of Chinese airlines and Continental Airlines.
