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。
Route performance analysis is an important task in the overall design phase of a passenger aircraft. The calculation results usually serve as a measure of the overall solution and as a general objective or constraint of optimization. In order to improve the computational speed and ensure the accuracy of analysis, a piecewise analytical method based on simplified equations of motion corresponding to typical flight modes is proposed. This method can be used to obtain all the performance parameters of the whole process of flight mission. Taking a typical passenger aircraft as an example, it is verified that the method meets the requirements of accuracy and calculation speed of route performance analysis in the overall design stage and is suitable for the overall analysis and optimization design of passenger aircraft.
