The Boeing 787 Dreamliner that will fly later this quarter has moved to the flight line. Fuel testing – the first in the next phase of extensive checks the airplane must undergo – will begin in the next few days.

In recent weeks, the 787 (designated ZA001) completed a rigorous series of tests including build verification tests, structures and systems integration tests, landing gear swings and factory gauntlet, which is the full simulation of the first flight using the actual airplane. With Chief Pilot Mike Carriker at the controls, the simulation tested all flight controls, hardware and software. The simulation also included manual and automatic landings and an extensive suite of subsequent ground tests.

All structural tests required on the static airframe prior to first flight also are complete. The final test occurred April 21 when the wing and trailing edges were subjected to their limit load – the highest loads expected to be seen in service. The load is about the same as the airplane experiencing 2.5 times the force of gravity.

“We continue to analyze the data, but the initial results are positive,” Fancher said. On April 13, the leading edge of the wing was subjected to its limit load while the rest of the airplane was subjected to loads expected at cruise. And in September 2008, the “high blow” high-pressure test was completed on the static airframe. During that test, the airframe reached an internal pressure of 150 percent of the maximum levels expected to be seen in service – 14.9 lbs. per square inch (1.05 kilograms per centimeter) gauge (psig).

Ground vibration testing, which measures the airplane’s response to flutter, also concluded on the second flight-test airplane, designated ZA002, at the end of this week. All the necessary structural tests required prior to first flight now are complete.

Now on the flight line, ZA001 will undergo additional airplane power and systems tests as well as engine runs. After completing final systems checks and high-speed taxi tests, the airplane will be ready for first flight, which is on schedule for later this quarter.

Boeing today announced that seven airlines will be the first to incorporate the new, spacious 737 Boeing Sky Interior starting in late 2010.

The interior features soft, blue-sky-like lighting overhead.

Stepping aboard a Boeing Next-Generation 737 with the new 737 Boeing Sky Interior, passengers will notice that the new entry offers a welcoming transition from the jetway. Cove lighting and curved architecture create a distinctive entry and greater openness in the cabin.

Passengers will immediately sense a soft blue sky overhead, created with colored light emitting diode or LED ceiling lighting that enhances the sense of spaciousness.

Drawing from years of research used to design the interior for the 787 Dreamliner, the 737 Boeing Sky Interior features new, 787-style modern sculpted sidewalls and window reveals that draw passengers’ eyes to the airplane’s windows, giving passengers a greater connection to the flying experience. On a more practical note, the sidewall design integrates the air vent so that before-flight security checks go more quickly for maintenance staff.

The new design offers larger, pivoting overhead stowage bins that add to the openness of the cabin. The bins give more passengers room to store a carry-on roll-aboard near their own seat, adding both extra convenience and extra legroom.
Boeing redesigned reading-light switches so passengers can find them more easily and avoid accidentally pressing the flight-attendant call button.

Speakers are integrated into each row’s passenger-service unit to improve sound and clarity of public address operations, while the new integrated air vent and improved noise-dampening materials reduce overall cabin noise.

Changes to the Next-Generation 737 are more than cosmetic: Boeing is targeting a 2 percent reduction in fuel consumption by 2011 through a combination of airframe and engine improvements. Airplane structural improvements will reduce drag on the airplane, reducing fuel use by about 1 percent. Boeing’s engine partner, CFM, is contributing the other 1 percent fuel savings through hardware changes to its engine.

Continental Airlines will make a Next-Generation 737-800 available to Boeing to flight test the performance improvements.
