Discussions on some problems of full-scale aircraft fatigue test
Full-scale aircraft fatigue test is a large,complex and long-lasting ground verification test required by the specification to sustain aircraft structural integrity program and meet airworthiness requirements.Several important issues of full-scale aircraft fatigue test,such as test objective,load spectrum,duration and scatter factor,are the key concern and widely discussed by aircraft designer/engineer.The scatter factor is also a problem studied by scholars.In recent years,aiming at the full-scale fatigue tests of several aircraft programs,the study and under-standing of the above-mentioned issues are introduced in this paper,and the fatigue design and full-scale fatigue tests of five fighter jets in China and abroad are compared.Some practical engineering suggestions for full-scale air-craft fatigue test are put forward.The research in this paper can provide important reference for other aircraft full-scale fatigue tests.
