Containment ability and structure optimization of U type protection ring

摘要：

　　High energy rotor uncontained failure can cause catastrophic damage effects to aircraft systems if not addressed in design.Generally the research of increasing the containment ability of the protection ring divides into material and structure levels.In this paper,an experiment of high-energy rotor disk fragments impacting on the protection ring is carried out.The result shows that the protection ring can resist the impact of three high energy disk burst fragments.Numerical simulations with a sufficiently refined finite element model are also carried out using LS-DYNA to compare with experiment.It is found that the steel protection ring almost absorbs half dynamic energy and holds three disk burst fragments at last.To study the influence of the groove depth of protection ring,another three different rings with same mass are designed.Simulation results show that the groove depth infects both the axial containment ability of the protection ring and the transfer process of energy.
