FIELD: engines and pumps.
SUBSTANCE: device comprises at least one detector sensitive relative to amount of accumulated ice and located inside aircraft engine air intake, system for measurement of this ice amount, system for comparison of ice amount to specified threshold value (S), and actuation system designed for initiation of response reaction whenever specified threshold value has been exceeded, besides, specified response reaction may constitute generation of warning alarm, increase of engine operation mode with certain time delay realised by engine control system or supply of hot air into front portion of engine downstream flow.
EFFECT: improved performance characteristics of device.
