The harmonic-balance-based one-shot method is developed for modeling the aeroelastic
response of three-dimensional configurations such as aircraft wings in transonic flow …

Dynamical systems often exhibit limit cycle oscillations (LCOs), self-sustaining oscillations of
limited amplitude. LCOs can be supercritical or subcritical. The supercritical response is …
