Experiment and numerical simulations were carried out to study the performance of bird strike with blades of an engine primary compressor. Firstly, the bird impact test, in which the bird weight, velocity and rotate speed of engine blades were 1000g, 195m/s, 8525 r/min respectively, was made in a vacuum space. Then the full scale finite element calculation model of bird striking on blades of an engine primary compressor was established, and the numerical simulation results are extremely identical with the test results with acceptable error to show the reliability of simulations. Also, the ability of engine blades against bird strike in different situations was researched. The results indicated that big bird impact leads to a worse situation compared with medium birds flock and small bird lock. Large deformation appears at the tip of the blades due to the impact at the tip part, while impact at the root and middle of the blades will cause a large concentrated stress around the root of blades. The research methods and our conclusions in the current paper are significant to the design of engine blades against to the bird impact.
