摘要单引擎飞机在起飞后不久发动机发生故障，飞行员被迫执行关机滑翔着陆。如果发动机在低空发生故障，别无选择，只能直着着陆。然而，当发动机故障发生在更高的高度时，飞机返回跑道的可能性就出现了。后一种选择有可能提高生存能力，特别是当周围地形变得不适合居住时。本研究的目的是确定在什么条件下返回跑道是一个可行和安全的选择。为此，折返着陆问题制定为一个最优控制问题，并使用直接优化技术的配置和非线性规划数值求解。在数值例子中采用的飞机模型涉及一架F-16战斗机，作为一个点质量建模。文中还讨论了风对最优折返机动的影响。
Abstract When a single-engine aircraft suffers an engine failure shortly after take-off, the pilot is forced to execute a power-off glide to a landing. If the engine failure occurs at a low altitude, there is no choice but to land straight ahead. However, when the engine failure occurs at a higher altitude, the possibility arises to turn the aircraft back to the runway. The latter option has the potential to improve survivability, in particular, when the surrounding terrain turns out to be inhospitable. The goal of the present study is to establish under what conditions returning to the runway is a feasible and safe option. To this end, the turn-back landing problem is formulated as an optimal control problem and solved numerically using the direct optimization technique of collocation and non-linear programming. The aircraft model employed in the numerical examples concerns an F-16 fighter aircraft, modelled as a point mass. The influence of wind on the optimal turn-back manoeuvre is also discussed.
