The modal approach with account of the first six natural modes is used to describe the motion (vibration) of blades. The results of calculating the aero elastic characteristics and aero damping coefficients are given for the blading row of fan SaM-146 operating a 0.85n rating under specified harmonic and coupled vibrations of blades for each natural mode separately and jointly (with account of 6 natural modes) with different blade vibration phase shift angles. The calculation results have demonstrated stable aero damping for all modes. Application - power machine building.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
