I noticed the 787 wing is more angled(upwards) than most aircraft.

From wikipedia:

"Raked wingtips are a feature on some Boeing airliners, where the tip of the wing has a higher degree of sweep than the rest of the wing. The stated purpose of this additional feature is to improve fuel efficiency, climb performance and to shorten takeoff field length. It does this in much the same way that winglets do, by increasing the effective aspect ratio of the wing and interrupting harmful wingtip vortices. This decreases the amount of lift-induced drag experienced by the aircraft. In testing by Boeing and NASA, raked wingtips have been shown to reduce drag by as much as 5.5%, as opposed to improvements of 3.5% to 4.5% from conventional winglets.[11] An increase in wingspan is generally more effective than a winglet of the same length, but may present difficulties in ground handling. For this reason, the short-range Boeing 787-3 design currently calls for winglets, instead of the raked wingtips featured on all other 787 variants."

Boeing 787 Dreamliner wing test looks 'positive'

Published on March 29, 2010 7:45 AM


Dow Jones Newswires | Boeing Co. said the results of a key airworthiness test for its long delayed 787 are "positive," but it will be weeks before the aircraft maker can say whether it's a success.

The aircraft maker said Sunday the test involved flexing the jet's wings while applying loads to the frame to replicate 150 percent of the most extreme forces the airplane could experience in flight. The wings were pushed up about 25 feet during the ground test performed at Boeing's Everett, Wash., factory.
The test took more than two hours, and thousands of pieces of data were collected to measure wing performance.

Boeing, based in Chicago, says the data will be reviewed over the next several weeks.

Boeing has been testing the plane and its systems for more than three months, after production delays and problems with carbon-fiber composite materials used in the plane put it nearly three years behind schedule. The first test plane made an unplanned landing last month after an engine lost thrust.

Japan's All Nippon Airways is scheduled for the first delivery of the 787 later this year. Boeing says airlines around the world have ordered 851 of the aircraft.

The largest 787 model has a range of up to 3,050 miles and can carry as many as 330 passengers.

That 3,000 miles range can't possibly be true. I thought the largest one would have a range of around 7-8,000 miles.

3,050 miles is the max range for the 787-3, the journalist just didn't look at the right graph, as usual.

How many test hours are still needed in order to start deliveries to the carriers?

Its not just the test hours but the number of tests both to qualify the plane and set the parameters (manual) for future pilots who would be using the plane like minimum take-off speed,flutter testing,etc and various checklists of what to do if certain things happen.

Normally takes about a year or 1.5yrs depending on the number of test planes and how well the tests go. Only after all these tests are verified both by the company and the aviation authorities can delivery start.

Yeah they have to fly around the world finding special conditions to fly in to meet all of the test requirements.
