The Dynamics of Helicopters with Nonlinearities on the Fuselage

Résumé

The present paper aims at evaluating the influence of nonlinearities on the dynamic response of an helicopter on the ground. Indeed, the helicopter on the ground might be faced to resonance and instability conditions that could lead to high vibration levels. Nonetheless, under the effects of nonlinearities, the dynamical behaviour of the aircraft could have substantial changes in which quasi-periodic and/or chaotic motions can occur. Poincaré section and bifurcation diagrams are evaluated for different helicopter configurations in order to highlight the dynamical behavior of helicopters with nonlinearities in the fuselage.
