Abstract: The temperature profile quality at engine combustor exit (before turbine) is aimportant technical index, which concern operational reliability and life of engine’s thermalcomponent, thus measuring temperature profile at the combustor exit (before turbine) in a engine isvery important. The method of measuring temperature profile before and after turbine in a typeturbojet is presented and the measured results is analysed. It can be concluded that the aftertemperature profile turbine differs from the one before turbine.
