分散式叶型梳状五孔针—全台压气机级间参数测量新方案

A DISTRIBUTED FIVE-HOLE PROBE RAKE ON STATOR BLADES FOR ROTOR EXIT MEASUREMENT OFA COMPRESSOR

Each tube of five-holes probe will be placed at the same radius on five different blades of stator.The diameter of the probe and the wall proximity effect are decreased.The distributed five-hole probe rake has been verified experimentally.Its dynamical frequency response is enhanced seven times.Its characteristics are improved.The parameter measurement of each rotor exit in a multistage compressor becomes practicable.
