Extensive research in recent years has focused on improving the current loss-of-control prevention systems and developing new strategies for safe path planning of the impaired aircraft. Success in developing such systems requires a comprehensive perception of the influence of damage on the aircraft’s dynamic behaviour and performance, and the effect of various failure degrees on the flight envelope confinement and the remaining safe maneuvers. This paper comprehensively describes the effects of lateral control surface failure on the NASA Generic Transport Model (GTM) flight envelope, defined by a set of attainable steady-state maneuvers herein referred to as trim points. The study utilises a large database of high-fidelity maneuvering flight envelopes computed for the unimpaired case and wide ranges of the aileron and rudder failure cases at different flight conditions. Flight envelope boundary is rigorously investigated, and the key parameters confining the trim points at different boundary sections are identified. Trend analyses of the impaired flight envelopes and the corresponding limiting factors demonstrate the effect of various failure degrees on the remaining feasible trim points. Results can be employed in emergency path planning with potential uses in the development of aircraft resilient control and upset recovery systems.

评估横向控制面失效对通用运输模型的影响：案例研究

近年来的广泛研究集中在改进当前的失控预防系统和制定受损飞机安全路径规划的新策略。成功开发此类系统需要全面了解损坏对飞机动态行为和性能的影响，以及各种故障程度对飞行包线限制和剩余安全机动的影响。本文全面描述了横向控制面失效对 NASA 通用运输模型 (GTM) 飞行包线的影响，该包线由一组可达到的稳态机动定义，本文称为微调点。该研究利用了一个高保真机动飞行包线的大型数据库，该数据库针对不同飞行条件下副翼和方向舵故障情况的完好情况和广泛范围计算得出。对飞行包线边界进行了严格的研究，并确定了限制不同边界部分的配平点的关键参数。受损飞行包线的趋势分析和相应的限制因素证明了各种故障程度对剩余可行配平点的影响。结果可用于紧急路径规划，并可能用于开发飞机弹性控制和异常恢复系统。受损飞行包线的趋势分析和相应的限制因素证明了各种故障程度对剩余可行配平点的影响。结果可用于紧急路径规划，并可能用于开发飞机弹性控制和异常恢复系统。受损飞行包线的趋势分析和相应的限制因素证明了各种故障程度对剩余可行配平点的影响。结果可用于紧急路径规划，并可能用于开发飞机弹性控制和异常恢复系统。
