The increased flexibility leads to an impingement on the bandwidth of the pilot biodynamics and the flight control resulting from the structural modes of vibration of the aircraft, which gives rise to Aircraft-Pilot-Coupling (APC). APC is a sustained oscillation resulting from a coupling between the pilot dynamics and the aircraft structural response while holding the inceptor, which can lead to passenger discomfort and in worst case scenario, an aircraft accident. The presented research project aims to develop the processes and tools required to predict and determine the margins of APC events using desktop simulation models. A developed lumped-discrete hybrid biomechanical model of the pilot, as well as a simplified lumped model of the seat and inceptor characteristics, are used to obtain their respective transfer functions and the transmissibility from the seat acceleration to the inceptor response. The transfer functions will then be integrated within a generic business aircraft aeroservoelastic model to form an Aircraft-Pilot-System (APS). The APS will be used to conduct open- and closed-loop stability analysis to identify APC conditions and their margins. Parametric studies representative of variations in pilot physical characteristics, aircraft loading, and flight conditions to identify the contribution of the aforementioned variations to APC are conducted. 收起
