Table 2 Pitch and plunge natural frequencies and damping coefficients obtained from experiments, estimated through static tests with varying pitch stiffness, while keeping all other structural parameters the same as given in Table 1.
Parameter | Value | ||
|---|---|---|---|
Natural frequency of the pitch mode, \((f_{\alpha })\) (Hz) | 3 | 3.6 | 3.95 |
Plunge to pitch natural frequency ratio, \(\overline{\omega }\) | 0.75 | 0.62 | 0.57 |
Pitch damping, \(\zeta _{\alpha }\) | 0.02 | 0.02 | 0.02 |
Plunge damping, \(\zeta _{y}\) | 0.04 | ||
