This project is focused on non-axisymmetric fan blade untwist and its effect on aeroelastic, aeroacoustic and aerodynamic performance of the fan.
Blade untwist is the structural deformation of a rotor blade due to operational stresses such as high centrifugal forces, and aerodynamic loading. This results in a difference between the blade’s “cold” static geometry (manufactured), and its “hot” geometry while running. This can influence the fan’s performance leading to issues such as reduced power output, increased fatigue on blades, and variation in vibration characteristics, reducing the life of the blade.
The project is mainly focused on developing fluid-structure coupling (CFD-FEA) modelling approaches, where the phenomena can be further analysed.
