Abstract: This paper discribes the experimental work on the research of disc bursting speed.The bursting speed tests for a series of disc models are made successfully.That means:such a difficult experimental technique has been mastered;and the reconstructed horizontal test rig is suitable for the research of disc bursting speed at normal atmospheric temperature and with heating.The results obtained from experiments and calculations are coincident.This work provides the basis for the further research on the bursting speed of aeroengine discs.
