Alenia Tests Dreamliner Horizontal Stabilizer

Alenia Aeronautica has successfully completed "ultimate load testing" of the Boeing 787 Dreamliner horizontal stabilizer. The test was carried out at the Laboratory of Structural Tests at Alenia's Pomigliano plant in Naples in the presence of Boeing engineers. The test is a fundamental step as part of Boeing's 787 certification efforts, and is key to clearing the Dreamliner for first flight. During the test, the stabilizer is subjected to the aerodynamic loads that could be experienced by the aircraft during flight in the most severe circumstances. Using a complex system of hydraulic jacks activated by specifically developed software, the test proves that the 787's horizontal stabilizer is capable of withstanding 150 percent of the load it is expected to see in its lifetime. "Our entire 787 team is fully committed to safety and reliability as demonstrated by this robust test program," said Mark Jenks, Boeing Commercial Airplanes vice president of Development for the 787 Program. "The successful testing of the horizontal stabilizer proves the capability of the composite material, design and construction." Over the past three months, static tests in the laboratory at Pomigliano have successfully bent the 787 stabilizer up and down and asymmetrically at maximum load, simulating three critical design conditions for the stabilizer.
