Abstract

When adjusting the gas turbine engine for operating parameters, taking into account pressure pulsations in the gas generator path, acoustic probes are used with the sensor moving out of the high temperature zone. The input waveguide included in the probe is an acoustically resonating element that significantly distorts the measurement result. Among the various corrective elements for acoustic probes, in practice, a special role is given to non-reflective loads in the form of long lines. During bench tests, it is often advisable for manufacturers to use structures made up of durite hoses with short sections of metal pipelines in addition to long lines. The attached material shows the test results of a model probe with several types of such agreed loads. The possibility of such a solution to increase the accuracy of measuring pressure pulsations in conditions of increased temperatures is shown.
