A mathematical model was developed for the cooled blade with a monocrystalline structure based on the geometric model of the blade and the alloy mechanical characteristics provided by the Customer. Numerical analysis was applied to the natural frequencies, vibration modes and distribution of relative dynamic stresses in the investigated blade at constant temperature. Stress localisation was detected during cooled blade vibration. The impact of azimuth orientation on the frequency spectrum was Product Description popup.authors popup.nrat_date 2020-04-02 Close
