Aiming at the containment structure of an aero-engine ultra-high speed air turbine starter, the containment capacity was analyzed and verified. The Johoson-Cook constitutive model was used to simulate its containment capacity with LS-DYNA software, and the containment test was carried out on the ultra-high speed rotating test bench. The experimental results show that: after the turbine disk is broken and files out, the main characteristics are the impact on the guide shell and the inner wall of the containment ring, and the circumferential sliding and scraping movement along the inner wall of the containment ring. The containment ring absorbs energy through its own deformation and the scraping and sliding between the inner wall and the turbine. The experiment results are in good agreement with the model simulation results, which shows that the containment structure can restrain the broken turbine disk, and has good containment capacity. The research results have a good guiding significance for the containment structure design of air turbine starter.
