Abstract

In this paper, the linear dynamic behavior of the helicopter in terms of characterization of the vibrations in a helicopter, is described. After analyzing in the time and frequency domain, vibrations are analyzed in geometrical and topological methods of chaos theory. Although the vibration in a helicopter are mainly periodic, the presence of chaotic dynamics using a systematic and detailed approach, is investigated. The aim of the research is to characterize the vibration mechanism based on a one set of measured data.
