论文摘要
本文在本文中制定了最小化氢驱动飞机的直接运营成本（DOC）作为最佳控制问题，并根据Pontryagin的最低原理解决。结果，假设在恒定高度上巡航，则确定最佳巡航速度。优化标准对应于代表氢燃料成本和时间依赖性成本之间权衡的功能的最小化，这些功能与成本指数表示的参数相关。该参数的价值由飞行员引入飞机的飞行管理系统（FMS）。 HY4飞机模型用于获得所提出的方法的数值结果。
The minimization of the Direct Operating Cost (DOC) for hydrogen-powered aircraft is formulated in this paper as an optimal control problem and is solved based on Pontryagin's minimum principle. As a consequence, the optimum cruise flight speed is determined assuming cruising at a constant altitude. The optimization criterion corresponds to the minimization of a functional representing the trade-off between the cost of hydrogen fuel and time-dependent costs, which are related by a parameter denoted by cost index. The value of this parameter is introduced by a pilot into the Flight Management System (FMS) of the aircraft. The HY4 aircraft model is used to obtain numerical results for the proposed methodology.
