摘要
本文分析了WJ5A发动机一次事故原因。据目视、荧光、断口和金相检验,在叶片组织中发现了明显的过烧特征。经与试验室模拟试验后的过烧组织进行对比,判断出局部超温达1290℃,这是引起事故的主要原因。文章还对发动机今后的安全使用提出了建议。
In this paper an analysis for an accident of WJ5A jet engine is made. On the basis of visual, fluorescent, fracture anrl metallographic examinations, obvious trace of overburn is revealed. By means of comparison with structure obtained at the laboratory simulation. We've determined that the temperature of the overheated area was reached to 1290℃, which caused the failure of the blades. Some recommendations are also put forward for the safty service of jet engine in future.
