The work is dedicated to solving the problem of the efficient estimation of technical state of GTE components by using the modern method processing of vibro-acoustic information. Unlike of usual spectral transforms, wavelet analysis of vibration signals GTE allows the same accuracy approximated as smooth functions and functions with sharp attacks; is a convolution of the signal with the wavelet function, which is displaced relative coordinates. Carried out stepwise analysis of vibration signals in flight and on the stand turbopropfan engine on a level of vibration speed in the nodes of the reducer, front and rear suspension.
