Abstract

A gas-turbine engine having means capable of determining the temperature inside a combustion chamber without mounting a special temperature sensor therein and of controlling the operation of the components according to the detected inside temperature of the combustion chamber, which is provided with means for measuring a resistance value of a glow plug driven with a constant current, means for measuring a flow rate of air supplied to the combustion chamber and means for determining an inside temperature of the combustion chamber by searching a specified temperature corresponding to a measured value of glow-plug-resistance and a measured air-flow-rate from a table holding therein resistance-temperature characteristic data of the glow plug predetermined for airflow rate as parameter.
