Table 3 Summary of the aeroelastic behaviour observed for \(\overline{\omega }\) = 0.67 case at different preset angle.
Preset angle | \(U_{cr}\) (m/s) | \(U_{fold}\) (m/s) | Aeroelastic response dynamics |
---|---|---|---|
\(0^\circ\) | 12.2 | 8.5 | Stall flutter LCOs |
\(5^\circ\) | 11.1 | 8 | |
\(10^\circ\) | 10.2 | 8.1 | |
\(15^\circ\) | 9.6 | 8.4 | |
\(20^\circ\) | 8.1 | 7 | Low amplitude LCOs \(\longrightarrow\) High amplitude LCOs |
