摘要

Turbojet engine is a complex technical object. It fulfils an important role in the civil and military aviation. Its undesired operation can lead to tragic accidents. Hence the large role takes the proper preparation for work and adequate regulation. The correctness of the engine work is tested periodically during ground tests. During the ground tests the responses to set engine control lever (DSS) shift is examined, thus means that the engine is examined from the "set point". During ground testing is not possible to reflect the impact of changing conditions during engine operation in flight so the engine is not tested on the noise signal. It turns out that it is the properties of the noise signal often have a decisive effect on the engine operation correctness and by that on the safety of the flight. Hence there is a need to develop methods to assess the state of the engine control signal from noise on the basis of standard ground test from the set point (delivered by the DSS).
