摘要An eigenvalue study can provide stability information for a system, and it is also an important part of aeroelastic analysis. In this work, an eigen system of a three-dimensional unsteady wake model is studied first to understand the physical meaning of wake dynamics. The blade- wake coupled system eigen-analysis is studied by the Floquet Theory. The eigenvalues of the Floquet matrix can determine system characteristics. The effect of wake dynamics on rotor blade eigenvalues can be seen by comparison with no inflow case. The results show that the inflow has a profound effect on blade dynamics, even at high advance ratios.
