在概念阶段制定两座飞机研制的各项指标中,起飞重量是一个关键要素,对两座飞机的各项总体参数有着决定性的影响。本文利用经验公式法,总结分析了各分类部件重量估算方法。建立了两座飞机起飞重量估算模型,分析了估算模型迭代方法及收敛性。
Of the various indicators developed for the two aircraft at the conceptual stage, take-off weight is a key element that has a decisive impact on the overall parameters of the two aircraft. In this paper, empirical formula method is used to summarize and analyze the weight of each classification component estimation method. Established two aircraft takeoff weight estimation model, analyzed the estimation model iteration method and convergence.
