Aeroelasticity of Multi-Stage Axial Compressors
In modern aircraft engines blade integrated disks (Blisks) are used more and more, because they permit a high pressure ratio per stage while being lightweight. Due to their low mechanical damping, they are highly sensitive to vibration excitation. Geometrical variances caused by wear and regeneration have a significant influence on the vibrational behavior. The main goal is therefore the prediction of the operational vibrational behavior of multistage compressors, while considering these variances and multi-stage coupling. The results enable accurate part life predictions.
