摘要
The effect of cubic aero-structural nonlinearities on aeroelastic flutter instability is here investigated. Focusing on the unstable flutter mode, the exact amplitude and frequency of the arising limit cycle oscillations are determined analytically. Both harmonic balance and multiple scales methods are adopted and perfect agreement of the explicit results is demonstrated, for the case of small perturbations of the aircraft speed in the neighborhood of the flutter instability.
