论文摘要
我们检查了两种平行混合动力飞机的配置，一架与发动机和电动机之间的机械连接无关。对于这两种设计，我们然后在飞机能源管理的背景下回顾了19座概念混合动力飞机的电源分配问题。然后，我们将原始的最佳控制问题表示为有限维优化，并验证二阶足够条件，以实现所获得的解决方案的全局最优性。然后，对初始飞机重量和飞行耐力的燃料消耗进行了敏感性分析。我们的模拟和理论结果阐明了为这类混合动力飞机在机上充电电池的有限好处，以减少$ CO_2 $排放。
We examine two configurations for parallel hybrid electric aircraft, one with, and one without, a mechanical connection between the engines and the electric motors. For this two designs, we then review the power allocation problem in the context of aircraft energy management for a 19-seat conceptual Hybrid Electric Aircraft. We then represent the original optimal control problem as a finite-dimensional optimization and validate the second-order sufficient conditions for global optimality of the obtained solution. This is then followed by a sensitivity analysis of the fuel consumption on the initial aircraft weight and flight endurance. Our simulation and theoretical results clarify the limited benefit of charging the battery in-flight for this class of hybrid electric aircraft to reduce $CO_2$ emissions.
