Reduction of equally spaced turbine nozzle vane excitation

摘要: A reduction in excitation amplitudes affecting turbine blade durability a nozzle assembly having plurality of vanes and blades, includes: identifying design the assembly; performing modal model analysis at least one blades design; reducing aerodynamic impact by ensuring that each is free aero-excitation from an upstream flow operating speed range; natural frequencies with respect to vanes; modifying trailing edge reduce amplitudes.
