摘　　要：航线性能分析是客机总体设计阶段的一项重要任务,其计算结果通常会作为总体方案的衡量指标以及总体优化的目标或约束。为了在提高计算速度的同时保证分析精度,提出了一种以典型飞行方式对应的简化运动方程为基础的分段解析方法。应用该方法可以获得航线任务飞行全过程的各项性能参数。以典型客机为算例,验证了该方法满足总体设计阶段对航线性能分析的精度和计算速度要求,适用于客机总体综合分析和优化设计。The analysis of en-route performance is an important issue in conceptual design of airliners.The en-route performance is usually considered as a design goal or constraint for the conceptual design optimization of airliners.To improve computational efficiency and reach high precision for the evaluation of en-route performance,a piecewise analytic model based on simplified motion equations for typical flight segments was established.The flight mission performance could be obtained using this model.A real airliner was used to verify the efficiency and precision of the piecewise analytic model.The results indicate that the piecewise analytic model is suitable for use in the conceptual design optimization of airliners.
