The Methods of Frequency Modulation of Fan Blade
Based on advanced aerodynamic performance ideas, fan blade is always designed to be low aspect ratio and large change in stagger angel from hub to tip. Such blade with singular surface is inconvenient to the frequency modulation during vibration optimizing. This paper presents three solutions to solve low order resonance and the coupling flexural-torsional vibration. The practical application shows the feasibility of these solutions.
