Abstract: The pressure change on the surface of the impeller blade at different values of its natural vibrations is considered in the article. It is noted that with high natural vibrations of the impeller, the pressure on the surface of the blade can only be positive or negative. At the same time, natural vibrations at a frequency of 1300 Hz cause a change in pressure along the blade length from negative to positive values.
Key words: impeller blade, natural vibrations, pressure.
