The research goal is to develop a method of experimental determination of modern high-performance GTE elements vibration parameters and to create scientific and technical basis in order to significantly reduce costs and the cycle GTE creation. The method of blade surface displacement calculating through the automated determination of the fringes order at each point, recorded interferograms of real GTE blade was developed and implemented. The method for determining the stress state of the blade surface allows to calculate the components of the strain tensor for any point, by varying amplitude of blade's vibration at the resonant frequency. This allows a 5...10 times to reduce the overall complexity of the researching. The experimental complex which includes three-dimensional structure of a holographic interferometer, a vibroexcitation and control the oscillation frequency of GTE blades system, a laser modulate system, machine vision and automated control of the experiment was created. Verification of the research methodologies and data processing programs has shown that the maximum difference does not exceed 10 percent. Developed and implemented method is patented the "Method of determining of the resonance vibrations shapes of GTE blades and device for its implementation".
