Application of Concurrent Test Management Technique in Full Civil Aircraft Fatigue Test

Abstract

Full aircraft structure fatigue test, as a part of civil aircraft structure airworthiness verification test, is the most complicated, the most expensive and the most time-consuming. Improving the efficiency of full aircraft structure fatigue test and shortening the fatigue test cycle have always been pursued, especially for fatigue test management technique. This paper introduces concurrent engineering which is applied to full aircraft fatigue tests such as MA600, ARJ21-700, Y12F tests. The traditional serial working mode is transformed into the parallel working mode. Concurrent test management technique is summarized and proposed creatively. The basic content and method of concurrent test management technique are described. Different requirements of the technique in different stages in a single test are analyzed. At the same time the management methods in multiple tests in the same factory are proposed. The practice shows that concurrent test management technique plays an important role in accelerating the cycle of full aircraft fatigue test. What’s more the technique is potential for further research and it is of application prospects.
