| Abstract: | Full-Scale fatigue test must be conducted for new type certificate of commercial airplane. It would also provide the verification of fatigue and damage tolerance design criteria and evaluation technology. Based on the new airworthiness regulation, this paper gives an overview on the full-scale fatigue test of commercial airplane structure. The 777 full-scale fatigue test is used in this paper as an example to describe various technical issues on the test methods, especially the test loading spectrum. |
