Study on drilling process of rotor blade spar layered polymer composite

On the basis of the developed device logging and recording acoustic signals from the cutting zone dependences of medium quadratic amplitudes of the frequency signals and graphs octave spectra received. Analysis of the obtained relationships and their relationship with dimensional characteristics arising defect - separation of layers of glasscarbonfiber prepreg and titanium foil. 

Keywords: VA, signal, diagnosis, layered polymer composite, titanium foil, glasscarbonfiber prepreg, separation of layers.
