摘要: 本文对进气边遭受外来物损伤的叶片的疲劳寿命进行了试验研究。首先对叶片进气边分区进行了模拟外来物损伤试验,并对外伤叶片和损伤后的修理叶片分别进行了疲劳试验。根据对比试验原理,分析了外来物损伤对叶片疲劳寿命的影响,提出了损伤叶片的允修范围。

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.

Key words: foreign object damage, blade repair, fatigue life, experiment of compari-son
