Структурная схема устройства определения параметров крутильных колебаний лопаток газотурбинных двигателей

Abstract

The block diagram of the device of determination of parameters of torsional fluctuations of shovels of GTE based on the analysis of the light stream reflected from in a special way of the created reflecting surfaces at end faces of shovels is offered. On the basis of the conducted pilot researches of the offered measuring converter the information time parameter allowing to determine parameters of torsional fluctuations of all shovels of a wheel is determined.
