| Abstract: | In this paper, the effect of Foreign Object Damage on the fatigue life of compressor blades and the repair scale of the FOD blades were investigated. Firstly, simulated .experiments of FOD on the leading edge of the blade were performed. Then, the damaged blades were fatigue tested. The data show that damages in different area of the leading edge of the blades have dissimilar effect on the fatigue life of the blades. The fatigue test of the damaged blades and repaired blades have been carried out respectively. According to the data, the repair scale of FOD blades was proposed. |
