EVERETT, Wash., Sept. 13 — Boeing has begun fatigue testing on the structural airframe of the 787 Dreamliner at the Everett, Wash., site. Fatigue testing involves placing the 787 test airframe into a test rig that simulates multiple lifecycles to test how the airplane responds over time.
“Unlike static tests, where loads are applied to the airplane structure to simulate both normal operation and extreme flight conditions, fatigue testing is a much longer process that simulates up to three times the number of flight cycles an airplane is likely to experience during a lifetime of service,” said Jim Ogonowski, structures vice president, Boeing Commercial Airplanes.
While the structural test program already has validated the strength of the airframe, fatigue testing looks at long-term, continued use. This is the natural progression of testing on a new airplane and part of the process to achieve U.S. Federal Aviation Administration certification.
EVERETT, Wash., Sept. 3 — Four of the five Boeing 787 flight test airplanes are conducting remote test operations this week. ZA005 continues testing from its base of operations in Seattle.
ZA001, the first 787, is taking a break from operations out of Edwards Air Force Base in California for a week’s worth of testing in Roswell, N.M. This is ZA001’s second visit to Roswell. Last month the airplane conducted wet-runway testing there. Testing in the days ahead will include rejected-takeoff conditions. ZA001 has been on remote deployment to Edwards Air Force Base for several weeks, with a focus on takeoff- and landing-performance conditions.
The second 787 is conducting high-latitude and cold-weather testing at Keflavik Airport in Iceland.
“We’ve been watching for the right weather conditions for some time,” said Scott Fancher, vice president and general manager of the 787 program. “The team was happy to see the forecast in Iceland met our needs and we deployed to Keflavik earlier this week.”
The hot weather in Yuma, Ariz., with temperatures in excess of 100 degrees Fahrenheit (38 degrees Celsius), has provided the necessary conditions for another set of tests happening on ZA003. Its deployment is expected to last about another week.
ZA004 has spent an extended time operating out of Victorville, Calif., conducting flight loads survey testing. This testing measures external pressure distributions throughout the flight envelope. ZA004 is set to do testing in Glasgow, Mont., after it wraps up its California testing.
Artificial ice shapes have been affixed to the leading edges of the wings and horizontal and vertical stabilizer of the fifth 787 to complete another group of tests required for certification. Ice-shape testing verifies the airplane’s performance in the presence of ice. Natural ice testing has already occurred.
“Flight test is staying very busy,” said Fancher. “We continue to be very pleased with the performance of the airplane. We’re definitely putting it through its paces, subjecting it to the harshest environments and conditions to ensure it is ready for revenue service.”
The 787 flight test fleet has conducted more than 1,650 hours of flying over more than 540 flights.
SEATTLE, Aug. 26 – Boeing Training & Flight Services has started 787 Dreamliner flight certification training following the provisional approval from the U.S. Federal Aviation Administration (FAA) for Boeing’s Seattle-based 787 flight training devices. As part of flight training, pilots train on a 787 flat panel training device and a 787 full-flight simulator. Both devices are manufactured by Thales.
“The innovations of the 787 have inspired us to develop the most effective training curriculum based on our customers’ training needs matched with efficient delivery and modern simulation tools,” said Sherry Carbary, vice president, Flight Services, Boeing Commercial Airplanes. “With the FAA’s approval on our flight training devices, we are embarking on an exciting journey toward delivering qualified and competent crews.”
The provisional designation will be removed once the airplane is fully certified. Local FAA offices will approve training courses customized for individual operators and these may be based on provisional approvals prior to certification of the airplane.
“We’re pleased with the progress we are making in ensuring our support products and services are ready for our customers,” said Mike Fleming, 787 director of Services and Support, Boeing Commercial Airplanes. “This is an exciting time for our customers and an important achievement for the entire Boeing team as we move toward delivery of the first 787.”
There are currently eight training suites at five Boeing Training & Flight Services locations around the world in Tokyo, Singapore, Shanghai, Seattle and Gatwick, U.K.
