AI Technical Summary
Technical Problem
In gas turbine engines, airfoils are susceptible to deflection under vibration loads, leading to wear and failure, increasing repair time and cost.
Method used
A deflection reduction mechanism, including a damping plate and a damper, is employed to absorb vibration energy and reduce bending deflection of the airfoil by coupling between the plate and the hub of the airfoil, and the damper is utilized to provide an anti-vibration response during engine operation.
Benefits of technology
This effectively reduces airfoil deflection, reduces wear and failure rates, and reduces repair time and component costs.
