R.Kh. Makayeva, A.Kh. Karimov, AM. Tzareva, E.М. Fatihova

The results of experimental and numerical investigations of resonance variation frequencies and modes for rectangular cantilever plates of constant thickness and gte compressor blades are presents. The investigations are carried out using the methods of holographic interferometry and finite elements. The table of resonance oscillation modes may serve as reference in determining resonance variation frequencies and modes of real blades. The results of investigations were applied at decision of practical problems.

Key words: compressor blades, rectangular plates, vibration, resonance frequencies and oscillation modes, holographic interferometry.
