A rapid evaluation method for maneuverability and airworthiness of multi-control surface aircraft based on torque AMS

To address the airworthiness design challenges of multi-control-surface aircraft during the conceptual design phase, a rapid maneuverability airworthiness evaluation method based on the torque attainable moment set(AMS) is proposed in this paper. The method translates relevant airworthiness requirements into constraints on the three-axis AMS and conducts rapid maneuverability airworthiness assessment by comparing the AMS coverage under normal and fault conditions of control surfaces. Time-domain simulations are performed for control surface design schemes that satisfy the AMS airworthiness constraints. The results demonstrate that the proposed AMS-based maneuverability airworthiness evaluation method can efficiently conduct preliminary assessments of airworthiness requirements for multi-control-surface conceptual designs, providing technical support for airworthiness design and functional hazard assessment of multi-control-surface systems.
