In order to study the oil-gas two-phase flow characteristics and oil sealing and leakage characteristics of aero-engine bearing chamber sealing system, an unsteady solution model of sealing chamber- carbon sealing structure-bearing chamber sealing system and sealing chamber-carbon sealing structure-anti-screw structure-bearing chamber sealing system based on Euler-Euler two-phase flow method was established. The experimental device of oil-gas two-phase flow in bearing chamber was designed and built. The accuracy of the solution method was verified by the experiment of oil sealing characteristics. On this basis, the oil-gas two-phase leakage flow characteristics of conventional bearing chamber sealing system and the bearing chamber sealing system with anti-screw structure under different working conditions were studied. The results showed that for the conventional bearing chamber sealing system, the higher rotational spee indicated, the greater oil leakage. The greater pressure difference also indicated the smaller oil leakage. The anti-screw structure can effectively reduce the oil leakage of the bearing chamber sealing system. When the speed was
