In principal, there are two approaches of experimental testing of flutter instabilities in blade cascades with respect to inter-blade phase angle. Those are travelling wave mode approach and aerodynamic influence coefficient approach. The latter one was used in this paper and different methods were used to evaluate the stability of the blade cascade consisting of five NACA 0010 profiles in both time and frequency domain. The results show that all of them yield very similar results but each of them has different pros and cons that are discussed in this paper.
