The amplitude-frequency characteristic of dynamic pressure signal through the semi-infinite and finite pressure tube was investigated

also its relationship with the shape of the inner diameter of the tube. With a semi-infinite pressure tube

a time-resolved total pressure probe with a Kiel structure was designed

and used to measure large angle inflow total pressure and calibrate its dynamic transfer function. The measurement results of the axial compressor rotor wake fields show that the semi-infinite pressure dynamic probe could get large gradient total pressure field

such as rotor wake and blade end flow. For design of the dynamic probe with pressure tube

both pressure tube diameter change and bending could attenuate signal energy

while semi-infinite pressure tube can availably keep dynamic pressure signal energy and decrease resonance effect.
