ЗОНДЫ ДЛЯ ИЗМЕРЕНИЯ ПУЛЬСАЦИЙ ДАВЛЕНИЯ В ГАЗОТУРБИННЫХ ДВИГАТЕЛЯХ (ОБЗОР)

Abstract

One of the key parameters bearing information on working processes during operational development of gas- turbine engines is pressure. Therefore special attention to the pulsating pressure measurement accuracy is paid. As a rule, installation of sensors to measure pressure with fluctuations directly in places of measurement is impossible. In this regard acoustic probes with frequency characteristics correction elements find broad application. Authors have considered it expedient to execute the survey analysis of the correcting elements efficiency on the basis of the available patents, articles and monographs. The report will be of interest to developers of probes for pressure with pulsations used in extreme operational conditions and technical officers in the area of tests and operational development of GTE.
