787 passes crucial "2C" static test
By Jon Ostrower on November 30, 2009 7:05 PM | Permalink | Comments (9) | TrackBacks (0)
Boeing successfully completed a critical static test today that re-created the conditions that caused the initial delamination in the 787 stringer caps, multiple sources tell FlightBlogger.
The test -- dubbed "2C" -- saw the composite wings of ZY997, Boeing's static test airframe, flexed to a deflection 18 feet without suffering the delamination first seen in previous testing back in May.
Today's 2C test, which exceeded 100% of the loads a 787 would ever encounter in service, is the third and final static test FAA requirement to clear the 787 for its first flight in December.
While the final data analysis is not yet complete, the successful static test is a significant step forward in validating the modification to the 787's side-of-body, which wrapped up installation on ZY997 on November 16.
The first two requirements included the high-blow test, completed in September 2008, and the 1G checkout, which was completed in March 20.
Sources say Boeing plans to test the 787 wing to ultimate load of 150% in the spring of 2010.
Boeing was unreachable for comment at the time of publication.

Wait for ultimate load test
Congratulations to Boeing if 787 has indeed cleared the Limit Load Test. About time too!
But 18 months ago, back at #31 on this thread I warned of difficulties in predicting capabilities of composites and of the criticality of the ultimate load test. That remains a big hurdle.
Few if any airplanes have failed static test at limit load, as the 787 did. Now that the first failure has been fixed, certification depends on proving that the whole airframe can sustain an additional 50% (i.e. design ultimate load). Since all structure was designed using analyses that have been proven defective by the wing to body failure, it will be pure good luck if the rest of the structure can sustain that extra 50% without premature failures somewhere else.

Boeing finally have another customer for the B747-8 Intercontinental
Boeing, Korean Air Announce Order for New 747-8 Intercontinental
Five airplanes worth $1.5 billion at list prices
(Seattle, December 4, 2009) -- Boeing (NYSE: BA) and Korean Air today announced an order for five 747-8 Intercontinental jetliners. Korean Air is the first Asian airline to order the passenger version of the new, fuel-efficient 747-8.
The airplanes have a total average list price value of $1.5 billion. Korean Air already has arrangements to operate seven 747-8 Freighters.
"This is a great day in the history of our long and enduring partnership with Korean Air," said Jim Albaugh, president and CEO of Boeing Commercial Airplanes. "The technologically advanced 747-8 Intercontinental is particularly well suited for Korean Air's operations. It will provide exceptional levels of passenger comfort, greatly enhanced fuel efficiency and reduced emissions and noise. The announcement comes at an exciting time as we move closer to the first 747-8 Freighter flight in early 2010."
Korean Air plans on flying the 747-8 Intercontinental on long-haul routes to the Americas and Europe.
"The 747-8 Intercontinental fills the void between the 300- and 550-seat airplanes in our future fleet," said Won Tae Cho, managing vice president of Korean Air Passenger Business Division. "The technological enhancements Boeing has made to this airplane will deliver exceptional economics and a flying experience that will thrill our customers, enabling Korean Air to provide Excellence in Flight to our customers."
The new 747-8 Intercontinental is stretched 18.3 feet (5.6 m) from the 747-400 to provide 467 seats in a three-class configuration, an additional 51 seats. It also offers a range of 8,000 nautical miles (14,815 km). Using the new GEnx-2B engines, the 747-8 provides airlines a quieter, more fuel-efficient airplane. The 747-8 also provides nearly equivalent trip costs and 13 percent lower seat-mile costs than the 747-400, plus 26 percent greater cargo volume.
The 747-8 also features a new wing design and an upgraded flight deck. The airplane interior incorporates features from the 787 Dreamliner, including a new curved, upswept architecture that will give passengers a greater sense of space and comfort, while adding more room for personal belongings. The architecture will be accentuated by lighting technology that provides smooth transitions for a more restful flight.
The 747 program is in the later stages of the 747-8 Intercontinental design phase. Assembly on the airplane is set to begin around mid-2010, with the first delivery of the passenger version scheduled for the fourth quarter of 2011.
With the addition of the Korean Air order, Boeing has secured 110 orders for the 747-8. Thirty-two of the orders are for the 747-8 Intercontinental, and the remaining 78 are for the 747-8 Freighter.

Boeing Successfully Completes 747-8 Freighter Engine Runs
'The Engines and All the Systems Performed As Expected'
(Everett, Wash., December 9, 2009) -- Boeing (NYSE: BA) successfully completed the first engine runs for the 747-8 Freighter. The milestone marks another step in the 747 program's steady progress in preparing for flight test.
"We are very pleased with the engines' performance during this test," said Mo Yahyavi, vice president and general manager of the 747 program. "The engines and all the systems performed as expected."
Engine runs began slightly before 10 a.m. (PST) Tuesday. During initial engine runs, the engines are started and operated at various power settings to ensure all systems perform as expected. The engine run test began with the auxiliary power system providing power to start the first of four General Electric GEnx-2B engines. The remaining three engines were started using the cross-bleed function.
Basic systems checks continued throughout the test. The engines were powered down and inspected and will be restarted following a technical review. The team completed a vibration check and monitored the shutdown logic to ensure it functioned as expected.
"This milestone is an exciting one for the GEnx-2B team and we anticipate the engines will continue the same high performance that we have experienced in our ground and flight tests," said Tom Brisken, general manager of the GEnx Program at GE Aviation.
The GEnx-2B engine is optimized for the 747-8. It helps provide customers with improved fuel efficiency, reductions in emissions and noise and a lower cost of ownership.

Could someone in the know confirm that the GENx engines on the B747-8 use bleed air to start the engines - on the B787 I understand that they use electric starter motors/generators.

From the Boeing Company ...
The Boeing Company is proud to announce the window for first flight is planned to open at 10 a.m. on Dec. 15 at Paine Field in Everett, Wash. This date is dependent upon final internal reviews, taxi test and receiving the final experimental ticket from the U.S. Federal Aviation Administration.
The aircraft financial community was instrumental in helping define the 787 product, and we'd like to invite you to view this achievement via the World Wide Web. Our Web site will present a live broadcast of the takeoff, landing and post-flight press conference. You can access this site at The Boeing Company or Boeing's New Airplane.
When you access boeing.com or newairplane.com, look for a banner like the one contained in this e-mail. The banner will display more information on the timing for first flight. The Web site will go live 24 hours prior to takeoff. The site features information about the airplane and our customers, partners and employees. It also will share videos highlighting other historic first flights and offer a behind-the-scenes look at flight testing.
The Web presentation will begin as the airplane start to taxi to the runway. A Boeing host will set the stage for takeoff. After the airplane leaves the ground, the Web site will carry live updates on flight status. The flight may last as long as three to five hours, so you will probably want to check back often. As the airplane prepares to land, the Boeing host will return and the landing and press conference will be carried live.
Please note that first flights are dynamic in nature and issues such as poor weather may affect timing. Please check the Web site for updates. We hope that you and your colleagues will join us in celebrating the first flight of Boeing's most advanced commercial airplane

Next step the sky
4:00 AM Monday Dec 14
Boeing's 787 Dreamliner undergoes testing on the tarmac at Paine Field in Washington state before its first test flight.
The first flight for the long-delayed 787 Dreamliner is scheduled for around 7am on Wednesday morning (NZT).
High-speed taxi testing was successfully completed yesterday at Everett in Washington state and the four to five-hour flight will go ahead if there are favourable conditions.
Boeing policy for first flight weather calls for good visibility, no standing water on the runway and gentle or no wind.
A successful maiden flight will mark a critical milestone for Boeing and will offer hope to impatient airlines which have seen the jetliner delayed for more than two and a half years.
Air New Zealand is the launch customer for the larger version of the plane, the 787-9, which was due to be delivered next year. The airline will now have to wait until 2013 before it gets the first of its eight planes on order.
The test flight has been delayed at least five times and has added billions of dollars to development costs, including penalties to airlines.
The 787 uses lightweight materials including carbon fibre-reinforced plastic and has an advanced electrical system.

Not RTO at this stage.
And even more confusing is this a photo of the 787 rotating on its take-off run .... before it's first flight.

Explains that one.
The video certainly looked like an RTO with reverse thrusts being deployed.
Looks like it might not today as at 4:40 am seattle time. This is the TAF for Boing field.

Anyone know what the first flight invloves? Duration? Manouvres etc? As i believe the gear has to stay down for the whole of the first flight?
Anyone involved with testing on here?

Can't tell you a whole lot more but 2.5 hours test flight provided wx stays good in the test area and at the 5 or so other diversion fields, and the arrival at Boeing Field Seattle. So long as they dont have tech issues of a serious nature and divert they should be completing the flight around 152100Z.
