Sexy lines make Boeing's new Dreamliner a fuel nightmare
From The Times
July 09, 2004

BOEING is being forced to reconsider the design of its new jet after admitting the distinctive shape would waste fuel.

The aircraft manufacturer originally claimed that the 7E7 Dreamliner, due to make its maiden flight in 2007, would be the most eye-catching aircraft in the skies.

But First Choice, the British holiday company which on Wednesday announced it was ordering six Dreamliners, said it would be pressing Boeing to redesign the plane.

Chris Browne, managing director of First Choice, said passengers did not care what the plane looked like as long as fares were cheap and the interior was comfortable.

She said: "Aerodynamics are far more important than the appearance. While it might be nice to look different, the key issue is to reduce fuel consumption."

As a launch customer, First Choice has the right to negotiate with Boeing over the design of the Dreamliner. The present design has an elongated nose and a tail fin that curves out of the fuselage rather than jutting upwards.

The design looks sleeker than existing snub-nosed aircraft but tests by Boeing's engineers have shown that it causes more drag and therefore increases fuel consumption.

Boeing has already been criticised by environmental groups for sacrificing efficiency for the sake of appearance.

Boeing director of environ ment Jeff Hawk said: "There is a trade-off in the design in which we lose a little in terms of overall efficiency. We wanted people to recognise the plane so they could identify with the brand."

But Boeing head of marketing Randy Baseler said that the manufacturer would be prepared to reconsider the design if airlines raised concerns about wasting fuel.

"Airlines are saying to us: 'We want to bring back the magic of flight.' They want something recognisable but we realise they don't want to pay a big fuel penalty for it. The tail is being studied very carefully and it could have some changes."

Mr Baseler said aspects of the Dreamliner's design, including extensive use of composite materials, would make it 20 per cent more efficient than existing airliners.

The Dreamliner will have between 200 and 300 seats.

Boeing still tweaking 7E7 design for fuel savings
Thursday July 8, 3:18 pm ET

SEATTLE, July 8 (Reuters) - Boeing Co. (NYSE:BA - News) said on Thursday it was still making minor design adjustments on its planned 7E7 wide-body jetliner to enhance its fuel economy even if it loses some of the sleekness shown in concept art.

"Some of the lines may change slightly, but people will still look at it and say, 'That's a 7E7,' and we will meet our fuel burn projections," Boeing spokeswoman Lori Gunter said.

Boeing officials, quoted in Thursday's Times of London newspaper, acknowledged a 7E7 design "trade-off" between fuel savings and visual appeal, saying they could still change the tail fin, currently shown curving gently off the fuselage unlike typical upright fins.

"The tail fin is being studied very carefully and it could have some changes," the Times quoted Randy Baseler, Boeing's vice president of commercial jet marketing, as saying.

Any changes would be relatively minor "standard refinement" of the design, Gunter said, stressing that the aircraft would burn 20 percent less fuel than the current Boeing wide-body 767, which it is replacing.

"The tail curve may not be quite as dramatic, but it may be. As the engineers work through it they find new design solutions," Gunter said, citing the extensive use of lightweight, nonmetal "composite" materials as a major source of efficiency.

Boeing on Wednesday unveiled the first European customers for the 7E7 -- British tour operator First Choice Holidays (London:FCD.L - News) and Italy's Blue Panorama -- boosting its total order book for the aircraft to 62.

Deliveries are projected to begin in 2008.

Gunter said wind tunnel tests have already proven the narrower 7E7 nose cone will not harm fuel efficiency, but stressed that nothing about the design is sacred.

"None of those (proposed) features will make it into the final design if they will harm efficiency," Gunter said.

Boeing is betting the 7E7, seating 217 to 289 passengers in different sub-models, will help it claw back market share lost to rival Airbus SAS which last year took the lead in aircraft deliveries for the first time.

Airbus, which has enjoyed considerable success with its own mid-sized A330 model, is now developing a massive 555-seat jet, the A380, in a bet that airlines will choose larger aircraft to ease air traffic congestion and cut operating costs.

I'd hardly call First Choice a launch customer. ANA have already ordered 50.

And aren't Airbus having weight problems with the A-380...?

More hulls not bigger aircraft...!

And more hulls means more jobs;)

Do even a minor search on Blue Panorama and it sounds like sister company to Global Air :8

Maybe Lukey-boy will also be a launch customer?
