摘要
现代飞机系统的设计日趋复杂,设计周期和研制风险也随之增加。因此,飞机系统的发展模式正由“性能决定设计,设计决定费用”向“性能和费用目标同时决定设计”转变,从而导致面向可承受性设计方法的出现。通过对可承受性定义的研究,在现有结构模型的基础上,讨论了面向可承受性的飞机总体方案评估方法的分析结构模型,并对相关参数的数学表述作了进一步的分析。籍此建立了更接近实际设计发展需求的飞机总体方案评估模型。
Aircraft design has become more and more complex in modem times, and also the design period and development risk are increasing. As a result, the mode of aircraft development has being moved from ＂Performance determines design, then design determines cost＂ to ＂Performance and cost goals determine design＂. Affordability oriented design methods came forth for this change. According to the definition of affordability and on the basis of existing analysis models, analysis models for evaluation of affordability oriented aircraft conceptual/preliminary design were investigated. And then, the mathematical descriptions of some parameters in the models were discussed. Finally, a model that further approaches the development of the actual designs, for the evaluation of aircraft conceptual/preliminary designs was established.
