Dynamic pressure blade type probe

摘要: The invention discloses a dynamic pressure blade type probe. interstage measurement space of miniaturized multistage axial-flow compressor is quite small, as the load an engine increased constantly, unsteady flow feature inside becomes more and salient, this causes great difficulty to field compressor. On one hand, since probe required have high frequency response, diameter cannot be too small; on other dimension not large in order prevent obstruction. A conventional common means satisfy test requirement. According invention, through directly fixing sensor surface blade, novel for measuring formed. When performed probe, effect detected accurate data can also obtained.
