Fuel tank is the key component in the study of aircraft survivability. Hydrodynamic ram effect is one of the main failure ways. Numerical simulation methods, test methods, impact factor and fuel tank structure design are the main research content for analyzing the effect of hydrodynamic ram on aircraft fuel tank. The de- velopment of latest research methods and achievements show that the materials of projectile, velocity and air proportions are the influence factors of hydrodynamic ram. The results of the research provide a reference for the deeply researching of hydrodynamic ram.
