Test bench of non-contact integrity control method of helicopter rotor blades

The article is devoted to experimental research of helicopter rotor blades. The paper presents the results of the test radio signal sensing blade models in the test bench. The analysis of the results and conclusions of the coherence duration and amplitude of the signal with the distance to the object of research, noted the advantages and disadvantages of this method. The evaluated of the test-bed and the possibility of expanding test bench functionality.
