Master thesis and internship[BR]- Master's thesis : Detuning solutions to mitigate vibration levels in blisk flutter and forced response[BR]- Integration internship

Abstract

Excessive vibrations in blisk, caused by aeroelastic phenomena such as flutter and forced response, compromise engine reliability and longevity. Detuning, achieved through intentional blade-to-blade variations arranged in specific patterns, has emerged as a promising strategy to mitigate these vibrations. This work studies detuning solutions for a blisk, with the dual objective of improving flutter stability margins and limiting forced response amplification.
