Discussion

Numerical analysis shows improved aeroelasticity and reduced displacements in wind turbines, indicating enhanced blade lifespan.

The bionic blade demonstrated a reduction in maximum deflection by 14.89% compared to the original wind turbine blade.
Experimental testing revealed the tip deflection of the bionic blade decreased by 54.74% from the original design.
Modal analysis and fluid-structure interaction methods were used to assess the performance of the bionic and original blades.
Improvements in the aeroelasticity of blades may lead to longer operational lifespans and reduced maintenance costs.

Chen et al. (2025) studied this question.
