Abstract：The containment for fan bladeout is the key of airworthiness certificationto commercial turbofan aero engine. The airworthiness certification authorities have developed a very strict technical requirements and validation criteria. However, as a destructive test, the fan blade out test is very expensive. In this paper, for hard-wall casing, it puts forward the target plate impact test, which simulates real fan bladeoutprocess.By high strain rate test of case material, the material model that includes the high strain rate effect is obtained.Then by the analysis for the test parameters, the high-precision simulation models can be established to evaluate the containment capability of the fan case. The high-precision simulation modelscan simulate the fan blade out test to increase the success rate. Moreover, based the simulation models,the relationship between thickness of the fan case and the load of fan blade out can be obtained.
