FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to definition of gas-dynamic flow parameters variation dynamics in bladed machines and channels, compressors, pipelines and diffusers in preset flow areas both in boundary areas and in gas flow nucleus and can be used for diagnostics of has turbine engines, analysis of flows in pipelines and channels with flow separation. Claimed method consists in measurement and registration of instant magnitudes of three flow arte constants (axial, radial and circumferential), pulsations of complete and static pressures in whatever plane relative to the nozzle. Note here that nozzle intake incorporates at least four pressure pulsation transducers.
EFFECT: higher accuracy and validity of measurements and flow structure analysis.
