Quasi Three-Dimensional Flutter Analysis of Single-row STCF4 Turbine Blade Cascade in Supersonic Flow
In this work the interaction of flutter-a self-excited self-sustained aeroelastic vibration phenomenon-with wake excitation is investigated using a harmonic balance frequency domain CFD code to solve the 2D inviscid Euler equations for a rotor in choke flutter operation. The wake deficit and the blade-motion amplitude (torsion) are varied.
