Abstract

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.

摘要

针对多操纵面飞机概念设计阶段操纵面适航性设计问题, 提出一种基于转矩可达集(AMS)的多操纵面飞机机动性适航快速评价方法。法将相关适航要求转化为三轴AMS的约束, 通过操纵面正常与故障状态的AMS覆盖性对比, 进行机动性适航快速评价, 对符合AMS适航约束的操纵面设计方案进行时域仿真。结果表明, 所提出的基于AMS机动性适航评价方法能够对多操纵面概念设计方案完成快速的适航要求初步评估, 为多操纵面适航性设计以及系统功能危害性评估提供技术支撑。
