The introduction of Flight Control System in modern rotorcraft calls for an improvement of the classical aeromechanics analysis methods used to investigate the dynamic stability of this kind of machines. It is important to consider from the preliminary design phase the analysis of Structural Coupling problems, i.e. those problems related to the interaction of the Flight Control System with high frequency structural dynamics. This paper presents an effective approach to develop multidisciplinary models that can tackle this peculiar type of problems. To better explain its potential, the proposed approach is applied to the investigation of structural coupling problems that may arise in the stability analysis of ground resonance.

Abstract
The introduction of Flight Control System in modern rotorcraft calls for an improvement of the classical aeromechanics analysis methods used to investigate the dynamic stability of this kind of machines. It is important to consider from the preliminary design phase the analysis of Structural Coupling problems, i.e. those problems related to the interaction of the Flight Control System with high frequency structural dynamics. This paper presents an effective approach to develop multidisciplinary models that can tackle this peculiar type of problems. To better explain its potential, the proposed approach is applied to the investigation of structural coupling problems that may arise in the stability analysis of ground resonance.| File | Dimensione | Formato | |
