FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire safety, namely to methods of detecting fire in aircraft engine compartments. For this, method of detecting fire in aircraft engine compartment by rate of temperature change, which consists in the fact that temperature is measured in monitored zone based on readings of linear thermoresistive sensor, calculating rate of temperature change, using this calculated value to determine fire, generating and transmitting corresponding fire information, characterized by that a derivative of temperature change rate is calculated, determining the sum of the rate of change of temperature and a value proportional to the derivative of the rate of change of temperature, comparing this sum with a given threshold value and, if this threshold value is exceeded, a fire signal is generated.
EFFECT: technical result is faster operation when detecting fire on rate of increase in average temperature in compartment of aircraft engine.
