IDENTIFICATION OF SURGE IN COMPRESSORS OF AVIATION TURBO-ENGINES BY VEYVLET-ANALYSIS

V.V. Panin, S.V. Enchev, A.V. Popov, A.Yu. Sidorenko

The article sets out the problem of the surge phenomena identification in the compressors aviation turbo-engines. Applicability of method recognition surge is grounded by veyvlet-decomposition of signals pressductors engine. The method of veyvlet-treatment of signals is definite. The algorithm of the wavelet transform of the developed device identification surge and prisurge states. It is marked special pattern of behaviour dispersion of distributing veyvlet-coefficients after 1…2 s to beginning of surge, that can be the informing sign of his offensive.

Key words: surge, veyvlet-coefficients, veyvlet-analysis, aviation turbo-engine, ortogonal decomposition.
