| Abstract: | The dynamic pressure measurement device and test technology are described in this study. The tip clearance unsteady flow development
from the inlet to the outlet of an axial-flow rotor was revealed by analyzing pressure frequency spectrum acquired from measuring
the unsteady pressure field of the tip endwall. The experiment provides test basis for thoroughly understanding the tip clearance
unsteady flow and building interaction models of tip clearance flow and main flow.
