內容簡介The Boeing Co. (Everett, Wash.) successfully completed a high-pressure test, known as "high blow," on the 787 Dreamliner static test airframe at its Everett factory on Sept. 27, but further work was postponed in the wake of a machinists strike, still unresolved as HPC went to press. The airframe pressure test was one of three static tests that must be cleared prior to first flight. During the test, the carbon/epoxy airframe reached an internal pressure of 150 percent of the maximum levels it is expected to see in service - 14.9 lb/in~2 (1.05 kg/cm~2). It took nearly two hours to complete the test because pressure was increased slowly to ensure airframe integrity.
