000012346 520__ $$2eng$$aDemand of composite fuel tank for the space vehicles keeps increasing globally in aerospace industry, and requires of a mean to predict its service life. Reported are an experimental investigation on the modal properties and dynamic response of composite fuel tank filled with fluid under external excitation in the transverse direction, and a vibration signal which was obtained when the composite fuel tank filled with water was under impulsion until it was failure. Proposed in this study is a method to detect the damage of the composite fuel tank with the scarce gradual damaged vibration signal. The experiment setup is also described in detail with inclusion of modeling a damaged situation of a structure. The damage detection algorithm is developed applying a residually generated form of a subspace-based covariance-driven identification method and the vibration signal analysis. Results of the modal identification and the damage detection are reported in this paper.
