Numerical analysis of the aeroelastic characteristics of a fan blade row has been carried out for different blade harmonic oscillation laws; and the aerodamping coefficients and modes of probable unstable oscillations have been determined. Calculation results have shown that the blade row is subject to selfexciting oscillations in the 4th mode. Application: axial turbomachines and compressors in different engineering areas (aircraft engine building and power machine building) Product Description popup.authors popup.nrat_date 2020-04-02 Close
