Smooth particle hydrodynamics (SPH) method and Lagrange method were used to simulate the process of hail impacting and the experiments of a Hail impacting on a plate, a titanium alloy sheet and a real fan disk were carried out. The results showed that the high strain rate constitutive model and Smooth particle hydrodynamics (SPH) method could simulate the process of hail impacting precisely; the simulation results had a good agreement with the experiment results. Based on this constitutive model and method, simulation of a hail of 1.1 cm diameter impacting into an aero engine at the state of climbing was carried out and the deformation of the blades after impacting was revealed. The result showed that impacting on the tip site of the blade would have the worst situation of plastic strain. An aero engine hail impacting test was carried out, and the deformation error of the impacted blade and simulation results was less than 10%. The front edge radius and the maximum thickness distribution of the blade were improved, and the anti-hail impacting ability of the blade was enhanced, and the improved design experiences had been accumulated for anti-hail impacting.
