Finite element analysis of fatigue behavior in different structured composite variable vanes under coupled aerodynamic load and natural frequency

Puntos clave

• Fatigue behavior varied significantly between composite vanes under aerodynamic load, highlighting their structural integrity.
• Key metrics revealed variable vanes experienced accelerated fatigue at specific natural frequency ranges.
• Finite element analysis assessed how aerodynamic load interacts with natural frequencies of the composite materials.
• The findings may suggest enhancements in vane designs, but results need real-world validation to ensure applicability.
