About the probes for measuring pulsations of pressure in the flowing part gas turbine engines

Evaluation of the stability of GTE compressor is provided in the measurement of pressure fluctuations in the frequency range from several Hz to several kHz. Because the sensors of the pressure fluctuations can not be located at the measurement points due to excessive heat, vibration and limited space for their installation used the lead-in channels - acoustic probes. Proposed science-based methodology for calculating the frequency characteristics of the probes with corrective elements on which the developed software tools to select their parameters. The developed software can process the information derived using acoustic probes during engine tests. To verify the validity of computational models of probes at the Department of SNPP SGAU established test facilities and measurement and registration set in place to test their frequency.
