The measurement method of rotating stall is presented. The oifferencebetween two signals and its frequency are determinea correcry on the basis of the spectrum analysis. Then
the number of rotating stall regime
its spread velocity and is for tained. The methods of the two-dimensional unsteady flow measurement are described. The.ocits distribution of the unsteady flow
for example a rotating stall cell
is obtained. A rotating gie a re method is applied to measuring the two-dimensional boundary layer. The results meater ehind a single rotor and a stator are shown in the paper. The contamination from dirt
the influeru of air flow temperature and the boundary layer flow field disturbance caused by probe hole had been consid-ered.
