To investigate an aero-engine auxiliary power unit turbine disk burst at the predict speed impact on the turbine casing containment

the casing containment test was conducted on a high speed spin tester. The prefabricating cracks were cut at three positions separated on the disk circumferential to make the disk burst at the predicted speed

the impacting process was recorded on the film by a hi-speed camera. The test results show that

the casing was penetrated and the disk fragments were successfully contained within the containment ring and sever plastic deformation was found in the containment ring. The numerical simulations were carried out using LS-DYNA to study the turbine casing containment

the simulation results show a good agreement with the test results. The results can be used as a reference for the engine disk containment design.
