    Abstract
  • Through experiments on a contra-rotating fan, the performance base line and stall margin have been analyzed at varies rotate speed matching and varies axial gap between two rotors. Used global five-hole pressure probe, the steadyflow field between contra-rotating rotors has been also measured, and the especial aerodynamic characteristic of contra-rotating fan has been analyzed more deeply when its rotate speed and axial gap changed. At last, basing on the experiment results and the same research in the world, this paper conclude some viewpoints on the means of raising pressure and stable range of a contra-rotating axial compressor system.
