abstract = "The dynamics of helicopter main rotor is described by a highly
nonlinear equations, and it is responsible to provide the
sustentation of the rotorcraft. The representative frequency to
this dynamics are associated to different regimes: unstable,
periodic, and even chaotic behavior. The system responses are
investigate performing several simulations under a set of
numerical values of frequency. One important subject is to
evaluate the goodness of the prediction of the simulated dynamics.
The dynamical analysis is performed by bred vector approach. The
breeding technique executes the model with a perturbed initial
condition. The difference between the reference and the perturbed
dynamics is called bred vector. The procedure can be employed
systematically, producing a time series of bred vector. The bred
vector magnitude is applied for addressing the predictability of
the model, i.e., the degree of confidence from the simulation.",
