WebOct 11, 2010 · The aerodynamic pressure is modeled using the quasi-steady first-order piston theory. Newton-Raphson iteration method is employed to obtain the thermal post-buckling deflection, while the linearized updated mode method is implemented in predicting the limit-cycle oscillation at elevated temperatures. Webmodes coalesce to create the resonance of flutter, i.e. when the pitch frequency and the plunge frequency become equal at a certain velocity called flutter velocity. Fit. 3 depicts a typical displacement-time curve for flutter phenomenon. Figure 3 Flutter displacement-time model Due to the multidisciplinary nature of flutter, a number of
