| الوصف: | The onset of non-synchronous-vibrations have been predicted for a composite open-test-case UHBR fan geometry by time-linearized simulations at part-speed conditions. In the current study, time-accurate simulations with harmonic blade oscillations have been conducted to investigate the non-linear behaviour. Results for different operating conditions show the evolution of aeroelastic stability. The lock-in of convected aerodynamic disturbances with structural vibration is analysed for different vibration amplitudes and frequencies. The simulations show the development of multiple wave-numbers, mode scattering and a non-linear dependency on vibration amplitude. The results indicate the possibility of limit-cycle prediction and the necessity of strongly-coupled methods for the assessment of NSV. |
