摘　　要：研究在考虑地球曲率情况下飞行器按指定高度长距离飞行问题。通过计算实时轨迹和理想轨迹的偏差,给出飞行器进行定高大圆飞行和定高圆周飞行时所需过载的实时计算方法,并建立这两种基本定高飞行方式的仿真模型。在此基础上,以定高船型和定高8字型机动建模为例,研究了定高组合模型的建模过程。仿真结果表明,所建立定高飞行模型具有强通用性、易实现性和易扩展性的特点、对飞行器的机动能力要求较弱且可在不同条件下实现较高精度的定高控制。An algorithm for the aircraft constant-altitude long-distance flight consider earth curvature studied. The required overload was calculated using the error between the real position and the ideal trajectory for two basic long-distance flight styles, i.e. great circle flight and circular flight, the simulation model of the two basic constant-altitude flight styles was established. On this basis, taking the modeling of constant-altitude box maneuvering and 8-shape constant-altitude flight as an example, the modeling process of constant-altitude combined model was studied. The simulation result shows the constant-altitude flight model can be widely used, easily implemented and easily expanded. Meanwhile, the model has little requirement for aircraft maneuvering capability and can achieve more precise constant-altitude controlling under different conditions.
