An Investigation of the Bifurcation Behavior of an F-18 Aircraft Model

Abstract Bifurcations of equilibria and limit cycles an F-18 aircraft model have been investigated in this paper based on one or two continuation parameters. First, it is shown that the can be a stable straight-and-level flight state by coordinating elevator deflection engine thrust fixing other Second, may disturbed perturbations out longitudinal plane get into lateral-directional motion mode branch point bifurcation. Third, when straight loses its stability, body axis angular rates will present periodic quasi-periodic pattern Hopf Neimark–Sacker Finally, bifurcation structure has exhibited, including generalized bifurcation, Hopf-Hopf fold-Neimark–Sacker Meanwhile corresponding curves two-parameter depicted with help numerical techniques.
